CAUTION
Before installation, careful consideration must be given to
how this system will operate if connected to any other piece
of mechanical equipment, i.e. a forced air furnace or air
handler, operating at a higher static. After installation, the
compatibility of the two pieces of equipment must be
confirmed by measuring the airflow’s of the Heat Recovery
Ventilator (HRV) Energy Recovery Ventilator (ERV) by
using the balancing procedure found in this manual.
It is always important to assess how the operation of any
HRV/ERV may interact with vented combustion equipment
(ie. Gas Furnaces, Oil Furnaces, Wood Stoves, etc.).
NEVER install a ventilator in a situation where its normal
operation, lack of operation or partial failure may result in
the backdrafting or improper functioning of vented combus-
tion equipment!!!

ERV Questions and Answers
What is the difference between an HRV
and an ERV?
and damp situation. In fact, about 2/3 of the energy
used by the air conditioner system is to remove mois-
ture. Therefore, when ventilating in the summer, less
moisture brought into the home means less work for
the air conditioner, and energy savings for you.
The core in an HRV (Heat Recovery Ventilator) trans-
fers heat from one air stream to the other. This is
called sensible heat. The term ERV (Energy Recovery
Ventilator) is usually used to describe a unit with an
enthalpic core that transfers moisture as well as heat
from one air stream to the other. This (moisture
transfer) is called latent heat.
During the winter, an ERV recovers some humidity
from the exhaust air, reducing the need for humidifica-
tion, if the required ventilation rate would make the
home too dry.
Enthalpic - what does it mean?
Enthalpy is the term used to describe the energy
content of air. This energy is a combination of the sen-
sible and latent heat. Therefore, a core which transfers
energy is called an enthalpic core.
What's the difference between this type of core
and a rotary type?
Here's a list of characteristics of the fixed plate core.
1. No rotating parts, so maintenance is easy and the
unit lasts a long time.
Is an ERV better than an HRV?
NOT NECESSARILY! In cold climates such as most of
North America, an HRV works better than an ERV.
This is because the air inside the home during the win-
ter months will be more humid than the outside air. An
ERV would transfer the latent heat (humidity) from the
exhaust air back into the incoming airstream. This will
aggravate moisture problems in the home and encour-
age the growth of mold and mildew. If the air in the
home is too dry for comfort, an ERV will not help. A
humidifier should be used to increase the humidity to a
comfortable level.
2. It is very flexible in terms of installation.
3. The core can easily be changed.
4. Because the supply and exhaust air streams are
completely separate, there is very little cross leak-
age of any dust or germs.
Can the core become clogged with dust?
Because the surface of the core is a turbulent flow
area, dust sticks to it easily; however, because the
inside of the element is a laminar flow area, virtually no
dust sticks to it.
Where do you use an ERV instead of an HRV?
An ERV is recommended for warm, humid areas with
heavy air conditioning use. As there is no defrost in an
ERV it is not recommended for areas where the tem-
perature drops below -4°C (25°F).
What is the maintenance?
About once a year you should use a vacuum cleaner
to remove the dust from the core's surface. DO NOT
WASH WITH WATER!
Is an air filter needed?
Why transfer moisture in the summer
(cooling season)?
To prevent clogging of the core, an air filter should
always be installed on the supply and exhaust sides of
the core.
The enthalpic core will allow moisture to be transferred
from a humid air flow to a dry air flow. This property is
useful in the cooling season if an air conditioning sys-
tem is used to lower the indoor humidity. You will then
have dry, cool air in the exhaust of the ERV, and warm
humid air in the supply stream. With these conditions,
the ERV will be able to transfer the moisture and heat
of the supply air to the exhaust air. In this way, the
ERV will supply to the home air which is cooler and
drier than outside. Remember that an ERV is not a
dehumidifier, and on its own will not take moisture out
of the air.
How much ventilation do I need?
During seasons when your windows and doors are
closed, the ERV should operate continuously when the
dwelling is occupied, and either continuously or inter-
mittently when not occupied.
For most installations the ERV will normally be set to
operate continuously on low speed with the option of
going to high speed as the need arises. For example;
if you are entertaining and there is a large number of
people present (some may be smoking), the unit
should be switched to high speed.
So why use an ERV?
Your ERV may be equipped with automatic or manual
switches, but all ERVs will have a manual speed con-
trol override.
A properly operating air conditioner will not only lower
the temperature in your house, but will also lower the
humidity level. This prevents an uncomfortable cold

Function and Controls
Operating the ControlAir 15
Self Test
Each time the HRV/ERV is powered/energized the self
test function will automatically initiate. During the self test
the HRV/ERV will cycle through all the speeds
available (1-5), test the damper motor operation and
will default back to the previous mode/speed selection,
(factory default is Speed 1). Total self test duration is
approximately 1 min. 30 sec.
Plugging in the HRV/ERV energizes the unit. A self
test function will be performed every time the
HRV/ERV is energized (refer to “Self Test” for more
details). After the self test has completed successfully
the HRV/ERV will default to Speed 1. This is the facto-
ry default setting. Follow the instructions found on the
HRV/ERV door to select desired mode and speed, or
refer to the instructions found on the following page.
Automatic Defrost Operation
(Not on all models)
The advanced technology of the digital microprocessor
automatically activates the defrost system only as it is
needed. To be an efficient heat recovery device, the
HRV/ERV must effectively provide for core defrost as well
as providing efficient heat exchange. As outdoor
conditions cool, the temperature sensor (thermistor)
tracks the supply air temperature. The thermistor then
sends its signal to the microprocessor (circuit board)
which initiates only the defrost cycle time required to
clear the core. On recirculating defrost models, the
core is defrosted when the supply air port is automati-
cally blocked off and exhaust air is redirected back
through the HRV/ERV. On damper defrost models, the
core is defrosted when the supply air port is automati-
cally blocked off and the warm air surrounding the
HRV/ERV is drawn in through the defrost port. The
mode indicator will flash RED during the defrost cycle.
By optimizing the defrost cycle, the HRV/ERV com-
bines money saving performance with a well designed
and reliable control system.
Control Module
Control Pad
ControlAir 15
Exploded view
Glossary
DEFROST MODE - to ensure reliable operation during cold
weather, the HRV/ERV will automatically cycle through its defrost
mode as needed. (not on all models)
Removing and relocating the Control Pad
DEHUMIDISTAT - a control device that senses the amount of
moisture in the air and will activate high speed fan operation
when the air moisture level exceeds the control setting. The opti-
mum air moisture level (or relative humidity [Rh]) in the typical
home is in the range of 30 to 50% Rh.
The Control Pad can be removed and installed in a
remote location (100’ wire length max). The Control
Pad can be installed in a 2x4 box with a “Decora” type
cover plate or can be installed in the optional
“Ventilation Dehumidistat” or “Air Sentry”. When the
Control Pad is installed in a remote location, all option-
al controls will still be wired to the Control Module on
the HRV/ERV. When remotely mounted on its own,
the Control Pad is wired to the Control Module by 3
wire (min. 20 gauge). Connect the colour coded termi-
nals to the corresponding terminals on the Control
Module. When the Control Pad is remotely mounted in
the Ventilation Dehumidistat or Air Sentry, refer to
optional controls page for wiring requirements.
RESET - whenever resetting of the HRV/ERV is required, simply
disconnect power for 30 seconds.
STANDBY MODE - the HRV/ERV is energized and waiting for
fan operation to be initiated by a remote device or manual over-
ride.
THERMISTOR - the HRV/ERV's temperature sensor which
measures electrical resistance in a known manner, as out-
door temperatures fluctuate.

To Select Mode of Operation for ControlAir 15
Press and hold the fan selection button on the Control Pad. After 5 seconds the control will begin to cycle each
mode holding each for 2 seconds. Release the button when the desired mode of operation is reached.
Modes of Operation
OFF
LED Indication
No LED’s illuminated HRV/ERV is off, no controls will
initiate operation.
ON/STANDBY
Steady Green LED and Yellow LED to indicate speed
HRV/ERV will run at speed selected in ventilation mode.
Standby mode is indicated by no speed indicator
illuminated. Optional remote controls will override standby or
selected speed into high speed.
20 ON / 40 OFF
Flashing Green LED and Yellow LED to indicate speed.
HRV/ERV will operate in ventilation mode at speed selected
for 20 minutes and OFF for 40 minutes.
RECIRCULATION
*Note: Not available on all models
Steady Red LED and Yellow LED to indicate Speed.
HRV/ERV will operate in recirculate mode at the selected
speed. Optional remote controls will override unit into high
speed ventilate mode.
To select speed
Momentarily press fan selection button and release. HRV/ERV will move into next speed. OFF
is indicated by no yellow LED illuminated. Speed 1 is the first yellow LED. Speed five is
indicated by a flashing speed 4 LED.
Automatic Defrost
During cold outdoor conditions the HRV/ERV will occasionally go into an automatic defrost
function, which will prevent ice from forming on the core. Defrost is indicated by a flashing Red
LED indicator.

humidity during the heating season. The dehumidis-
tat operates in % of RH (relative humidity) with 80
being high and 20 being low. The average person is
comfortable between 30-50%.

house is reduced, the HRV/ERV will revert back to its
previous setting.The dehumidistat should be set to off
for all seasons except the heating season.
Note: If your HRV/ERV is equipped with an internal
and an external dehumidistat, the internal one can be
turned off and not used.
The dehumidistat will override the ventilator to high
speed when the moisture level in the home exceeds

Installation
Location
Connecting Appliances to the HRV/ERV
It is not recommended that any of the following appli-
ances be connected to the HRV/ERV:
The HRV/ERV must be located in a heated space
where it will be possible to conveniently service the
unit. Typically the HRV/ERV would be located in the
mechanical room or an area close to the outside wall
where the weatherhoods will be mounted. If a base-
ment area is not convenient or does not exist, a utility
or laundry room may be used.
• clothes dryer
• range top
• stovetop fan
• central vacuum system
Attic installations are not normally recommended due
to:
Lint, dust or grease will collect in the HRV/ERV, dam-
aging the unit.
NOTE: Connecting any of these to the HRV/ERV will
invalidate your warranty.
A) the complexity of work to install
B) freezing conditions in the attic
Installing the Drain Line and P-Trap
(not on all models)
C) difficulty of access for service and cleaning
Sufficient clearance at the front of the access door is
required for servicing the air filters and core. A mini-
mum of 25" (635 mm) clearance is recommended so
the door can be opened. Four PVC reinforced poly-
ester hanging straps are provided for hanging the
HRV/ERV from the basement floor joists.
When defrosting, the HRV/ERV may produce some
condensation. This water should flow into a nearby
drain, or be taken away by a condensate pump. The
HRV/ERV and all condensate lines must be installed
in a space where the temperature is maintained above
the freezing point.
Mounting
At the bottom of the cabinet there are prepunched
hole for the drain pan connectors (see below). Insert
the drain spout through the hole in the drain pan. Do
not forget the “O Ring” which seals the connector to
the pan. REMEMBER TO HAND TIGHTEN ONLY the
washer and lock nut which hold the drain connector in
place.
The hanging straps should be attached to the unit at
the top end corners (mounting screws are already
located on the HRV/ERV case). Securely fasten the
other end of the straps to the floor joists with wide
head nails (not supplied), making sure the unit is level.
The straps are designed to reduce the possibility of
noise, resonance or harmonics; therefore using the full
length of the strap between the HRV/ERV and the
floor joists is recommended.
Construct a P-Trap using the plastic tee connector.
Cut two lengths of hose and connect each piece to an
end of the “T” fitting, then connect the other ends to
the two drain spouts. Allow the "T" fitting to point
upwards, and connect the drain line. Tape or fasten
base to avoid any kinks. This creates a “trap” which
will hold some condensate and prevent odours from
being drawn up the hose and into the fresh air supply
of the HRV/ERV.
Electrical
The HRV/ERV should be plugged into a standard des-
ignated (120VAC) electrical outlet with ground. It is not
recommended that an extension cord be used for this
appliance. If further wiring is required, then a licensed
electrician should make all electrical connections. It is
recommended that a separate 15 amp/120 volt circuit
be used.
WARNING:
PRE-PUNCHED HOLES (2)
In order to prevent electric shock when cleaning or
servicing the HRV/ERV, it is extremely important to
confirm the polarity of the power line that is switched
by the safety (disconnect) switch. The hot line (black)
is the proper line to be switched. To confirm the proper
polarity, use a voltmeter or test lamp to ensure there is
no power after the switch when the door is open.
Check between that point and ground (on the cabinet).
This must be done as dwellings are occasionally wired
improperly. Always make sure that the HRV/ERV is
properly grounded.

Warmside Ducting
• At least 18" (457 mm) above ground or above the

To maximize airflow in the ductwork system, all ducts
should be kept short and have as few bends or elbows
as possible. Forty-five degree elbows are preferred to
90° elbows. Use “Y” tees instead of 90° elbows when-
ever possible.
• At least 3' (1 m) away from the corner of the
building
• Not near a gas meter, electric meter or a walkway
where fog or ice could create a hazard
All duct joints must be fastened with screws, rivets or
duct sealant and wrapped with a quality duct tape to
prevent leakage. We recommend aluminum foil duct
tape.Galvanized ducting from the HRV/ERV to the liv-
ing areas in the house is recommended whenever
possible, although flexible duct can be used in moder-
ation if necessary.To avoid possible noise transfer
through the ductwork system, a short length (approxi-
mately 12 " or 300 mm) of non-metallic flexible
insulated duct should be connected between the
HRV/ERV and the supply/ exhaust ductwork system.
• Not into a garage, workshop or other unheated
space
When installing the weatherhood, its outside perimeter
must be sealed with exterior caulking.
Installing the ducting from the
weatherhoods to the HRV/ERV
The inner and outer liners of the flexible insulated duct
must be clamped to the sleeve of the weatherhoods
(as close to the outside as possible) and the appropri-
ate port on the HRV/ERV. It is very important that the
fresh air intake line be given special attention to make
sure it is well sealed. A good bead of high quality
caulking (preferably acoustical sealant) will seal the
inner flexible duct to both the HRV/ERV port and the
weatherhood prior to clamping.
The main supply and return lines to/from the
HRV/ERV must be 6 inches (150 mm) minimum.
Branch lines to the individual rooms may be as small
as 4 inches (100 mm), but 5 inch (125 mm) lines are
preferred .
All ducts running through attics and unheated spaces
must be sealed and insulated to code.
To minimize air flow restriction, the flexible insulated
duct that connects the two outside weatherhoods to
the HRV/ERV should be stretched tightly and be as
23
Supply Air Ducting
In homes without a forced air furnace, fresh air should
be supplied to all bedrooms and living areas, exclud-
ing bathrooms, kitchen and utility areas. It should be
supplied from high wall or ceiling locations. Grilles that
diffuse the air comfortably such as the Techgrille™
are recommended.
Dampers and Grilles
The use of balancing dampers and/or adjustable
grilles to balance the flow rates into various rooms is
recommended. We suggest TECHGRILLE™ air dif-
fusers.
• The TECHGRILLE™ is available in 4", 5", 6" and 8" (100,
125, 150 and 200 mm) sizes.
If the floor is the only option available, then special
care should be taken in locating grilles. Areas such as
under baseboard heaters will help to temper the air.
Also optional inline duct heaters are available for
mounting in the supply duct work to add heat if
required.
• The TECHGRILLE™ is a round, fully adjustable grille,
which provides superior, quiet air distribution.
In homes with a forced air furnace, you may want to
connect the HRV/ERV to the furnace ductwork (see
information below).
Direct Connection to Furnace Ductwork
Should you wish to hard duct the supply air directly
into the cold air return of the furnace, remember to
check the air flow balance of the HRV/ERV with the
furnace fan both "ON" and "OFF" to determine that it
does not imbalance the unit more than 10%. Also, it is
advisable to include a short length of fabric flex duct or
other non-metallic connector in this hard ducted line in
order to keep the HRV/ERV separately grounded
(electrically) from the furnace. This will avoid a possi-
ble shock hazard to service people if a short to ground
develops in one of the devices.
Indirect Connection to Ductwork
Techgrille Air Diffusers
If permitted by local codes, an indirect connection may
be made between the HRV/ERV supply duct and the
furnace return plenum. The fresh air from the unit may
be directed at a grille installed in the cold air return
duct of the furnace. The fresh air supply outlet from
the unit should be no closer than 4 inches (100 mm)
and no more than 12 inches (300 mm) from the grille.
We recommend the use of high mounted wall returns
with grilles. The exhaust air duct from the kitchen
should never be connected to a range hood. Instead,
the exhaust grille should be mounted high on the wall
at least 4 feet (1.2 m) horizontally away from the
stove. A "flip-up", 6" X 10" (150 X 250 mm) rectangu-
lar kitchen grille with removable grease filter is
available (Part No. 10-002).
Stale Air Exhaust System
The stale air exhaust system is used to draw air from
the points in the house where the worst air quality
problems occur. It is recommended that return air
ducts are installed in the bathroom, kitchen, and laun-
dry room. Additional return air ducts from strategic
locations (i.e. greenhouse, atrium, swimming pool,
sauna, etc.) may be installed. Also, the furnace return
duct may be used to exhaust from. In this method, the
exhaust air is not ducted back to the HRV/ERV with
"dedicated lines" from bathrooms, kitchens, etc.
Instead, the exhaust air is drawn out of the cold air
return of the forced air furnace. This method has
become popular and provides good ventilation when
installed in accordance with the instructions. The fur-
nace blower must be running when the unit is
operating for this system to be effective.
Dampers should be located just prior to the HRV/ERV
to balance the stale air exhausted out of the house
with a fresh air supply entering the house.

Please Note: It is the responsibility of the installer to ensure all ductwork is sized and
installed as designed to ensure the system will perform as intended. All air movement
devices have a performance curve. The amount of air (CFM) that an HRV/ERV will deliver is
directly related to the total external static pressure (E.S.P.) of the system. Static pressure is
a measure of resistance imposed on the blower by length of duct work/number of fittings
used in duct work, duct heater etc.

Pitot Tube Air Flow Balancing
It is necessary to have balanced air flows in an HRV/ERV. The vol-
ume of air brought in from the outside must equal the volume of air
exhausted by the unit. If the air flows are not properly balanced,
then;
Insert the Pitot tube into the duct; pointing the tip into the airflow.
For general balancing it is sufficient to move the pitot tube around in
the duct and take an average or typical reading. Repeat this proce-
dure in the other (supply or return) duct. Determine which duct has
the highest airflow (highest reading on the gauge). Then damper
that airflow back to match the lower reading from the other duct.
The flows should now be balanced. Actual airflow can be deter-
mined from the gauge reading. The value read on the gauge is
called the velocity pressure. The Pitot tube comes with a chart that
will give the air flow velocity based on the velocity pressure indicat-
ed by the gauge. This velocity will be in either feet per minute or
metres per second. To determine the actual airflow, the velocity is
multiplied by the cross sectional area of the duct being measured.
• The HRV/ERV may not operate at its maximum efficiency
• A negative or positive air pressure may occur in the house
• The unit may not defrost properly
• Failure to balance HRV/ERV properly may void warranty
Excessive positive pressure may drive moist indoor air into the
external walls of the building where it may condense (in cold weath-
er) and degrade structural components. May also cause key holes
to freeze up.
Excessive negative pressure may have several undesirable effects.
In some geographic locations, soil gases such as methane and
radon gas may be drawn into the home through basement/ground
contact areas. Excessive negative pressure may also cause the
backdrafting of vented combustion equipment.
This is an example for determining the airflow in a 6" duct.
The Pitot tube reading was 0.025 inches of water.
From the chart, this is 640 feet per minute.
The 6" duct has a cross sectional area of = [3.14 x (6"÷12)2]÷4
= 0.2 square feet
Read the Application Warning on the front of this manual!
Prior to balancing, ensure that:
The airflow is then:
640 ft./min. X 0.2 square feet = 128 cfm
1. All sealing of the ductwork system has been completed.
For your convenience, the cross sectional area of some common
round duct is listed below:
2. All of the HRV/ERV's components are in place and functioning
properly.
3. Balancing dampers are fully open.
4. Unit is on HIGH speed.
5. Air flows in branch lines to specific areas of the house should
beadjusted first prior to balancing the unit. A smoke pencil used
at the grilles is a good indicator of each branch line's relative air
flow.
6. After taking readings of both the stale air to the HRV/ERV duct
and fresh air to the house duct, the duct with the lower CFM
([L/s] velocity) reading should be left alone, while the duct with
the higher reading should be dampered back to match the lower
reading.
7. Return unit to appropriate fan speed for normal operation
Balancing Procedure
The following is a method of field balancing an HRV/ERV using a

Balancing Collar Instructions
Push and turn with slotted
screwdriver. Damper
automatically locks when
pressure is released.
When connecting ductwork
to the collar, take note where
screws are located. Screws
should be located no further
than 1/2” from outside edge
of collar, so as not to impede
operation of the damper.
Hard/Rigid
ducting
1/2”
Installations where the HRV is ducted directly to
the return of a furnace may require additional
dampening on the fresh air to building duct.
This is due to the high return static pressures
found in some furnace installations.

Maintenance Routine for HRV (for ERV, see following page)
1. Inspect Exterior Hoods at least once a month.
Make sure exhaust and fresh air supply hoods are not
blocked or restricted by leaves, grass, or snow. In win-
ter, it is especially important to make sure snow is not
blocking the hoods or that frost has not built up on the
wire mesh (bird screen).
4. Motors - Maintenance Free
5. Drain (condensate) Line - Clean once a year
Inspect drain line, drain spout and “P” trap for block-
age, mould or kinks. Flush with warm soapy water and
replace if worn, bent or unable to clean.
6. Clean Duct Work if Required
WARNING: Blockage of hoods may cause an imbalance.
The duct work running to and from the HRV may accu-
mulate dirt. Wipe and vacuum the duct once every
year. You may wish to contact a Heating/Ventilation
company to do this.
2. Clean Air Filters (clean twice a year)
The standard filters equipped with your HRV are
removable and washable.
7. General Maintenance - Twice a Year
Wipe down the inside of the cabinet with a damp cloth
to remove dirt, bugs and debris that may be present.
a) simply open access door and slide core out
b) remove filter clips
c) once clips are removed filters can be taken off the
core to be rinsed with water or a combination of
mild soap and water. Do not clean in the dishwash-
er
8. Cleaning the Fans
Fans may accumulate dirt causing an imbalance
and/or excessive vibration of the HRV. A reduction in
the air flow may also occur. In new construction this
may result within the first year due to heavy dust and
may occur periodically after that over time depending
on the outdoor conditions.
d) to re-assemble, place clean filter(s) (wet or dry)
back into their positions against the core and return
clips to their original position
e) slide core back into its’ original position
• unplug the HRV and open the service door
• remove the core
3. Clean Core Twice a Year
a) open access door.
• remove ducting (metal and/or flexible insulated
type) from the red and/or blue ports which are
connected immediately inline with the fan assem-
bly
b) carefully grip ends of core and pull evenly outward.
Core may be snug, but will slide out of the channel
c) once removed from the cabinet remove filters
• use a small brush, such as an old toothbrush or
pipe cleaner, and insert first
d) wash core in warm soapy water (do not use dish-
washer)
(a) through the large opening of the fan
assembly and then
e) install the clean filters
f) install clean core
(b) through the smaller opening in the end
of the fan assembly.
Note: Core installation label on the outer end of the
core.
• scrub individual fan blades until clean. Avoid
moving or damaging balancing flat weight, clip is
usually found on one or more of the fan blades
To install the clean core:
a) first mount the bottom flange of the core guide into
the bottom H channel approximately 1/4” (6mm)
• vacuum and wipe
b) mount the left or right side flange of the core guide
approximately 1/4” (6mm) followed by the other
side
• reassemble making sure ducting is reattached
firmly and insulation and moisture barrier are
sealed and taped
c) mount the top flange of the core guide into the top
H channel approximately 1/4” (6mm).
Before attempting this task, thought should be given to
having a qualified service technician complete the ser-
vice work.
d) with all four corners in place and the core straight
and even, push hard in the centre of the core until
the core stops on the back of the cabinet.
NOTE: Core will appear to stick out from cabinet approxi-
mately 1/8” (3mm). This is designed this way so that the
access door will fit tight against the core.

Troubleshooting your HRV/ERV System
SYMPTOM
CAUSE
SOLUTION
Poor Air Flows
• 1/4” (6 mm) mesh on the outside hoods is plugged
• filters plugged
• clean exterior hoods or vents
• remove and clean filter
• core obstructed
• remove and clean core
• house grilles closed or blocked
• dampers are closed if installed
• poor power supply at site
• ductwork is restricting HRV/ERV
• improper speed control setting
• HRV/ERV airflow improperly balanced
• check and open grilles
• open and adjust dampers
• have electrician check supply voltage at house
• check duct installation
• increase the speed of the HRV/ERV
• have contractor balance HRV/ERV
Supply air feels cold
• poor location of supply grilles, the airflow may irritate
the occupant
• locate the grilles high on the walls or under the baseboards,
install ceiling mounted diffuser or grilles so as not to directly
spill the supply air on the occupant (eg. over a sofa)
• turn down the HRV/ERV supply speed. A small duct heater
(1kw) could be used to temper the supply air
• placement of furniture or closed doors is restricting the
movement of air in the home
• outdoor temperature extremely cold
• if supply air is ducted into furnace return, the furnace fan
may need to run continuously to distribute ventilation
air comfortably
Dehumidistat is not Operating
• improper low voltage connection
• external low voltage is shortened out by a staple or nail
• check dehumidistat setting it may be on OFF
• check that the correct terminals have been used
• check external wiring for a short
• set the dehumidistat at the desired setting
Humidity Levels are too High
• dehumidistat is set too high
• set dehumidistat lower
Condensation is appearing on the windows
• HRV/ERV is undersized to handle a hot tub, indoor pool, etc.
• lifestyle of the occupants
• cover pools, hot tubs when they are not in use
• avoid hanging clothes to dry, storing wood and venting clothes
dryer inside. Heating wood may have to be moved outside
• vent crawl space and place a vapour barrier on the floor
of the crawl space
• moisture coming into the home from an unvented or
unheated crawl space
• moisture is remaining in the washroom and kitchen areas
• ducts from the washroom should be sized to remove moist
air as effectively as possible, use of a bathroom fan for
short periods will remove additional moisture
• on humid days, as the seasons change, some condensation
may appear but the homes air quality will remain high with
some HRV/ERV use
• condensation seems to form in the spring and fall
• HRV/ERV is set at too low a speed
• increase speed of the HRV/ERV
Humidity Levels are too Low
• dehumidistat control set too low
• blower speed of HRV/ERV is too high
• lifestyle of occupants
• set dehumidistat higher
• decrease HRV/ERV blower speed
• humidity may have to be added through the use of humidifiers
• have a contractor balance HRV/ERV airflows
• HRV/ERV air flows may be improperly balanced
HRV/ERV and / or Ducts Frosting up
• Note: minimal frost build-up is expected on cores before
unit initiates defrost cycle functions
• HRV/ERV air flows are improperly balanced
• malfunction of the HRV/ERV defrost system
• have HVAC contractor balance the HRV/ERV
• ensure damper defrost is operating during self-test
Condensation or Ice Build Up in Insulated Duct to
the Outside
• incomplete vapour barrier around insulated duct
• a hole or tear in outer duct covering
• tape and seal all joints
• tape any holes or tears made in the outer duct covering
• ensure that the vapour barrier is completely sealed
Water in the bottom of the HRV/ERV
• drain pans plugged
• improper connection of HRV/ERVs drain lines
• HRV/ERV is not level
• ensure O-Ring on drain nozzle sits properly
• look for kinks in line
• check water drain connections
• drain lines are obstructed
• make sure water drains properly from pan
• HRV/ERV heat exchange core is not properly installed
