ZONE THERMOSTAT CONTROL RELAYS — A unique
feature of the Aquazone system control panel is the capability to
add zone thermostat control relays. This feature is used when the
Aquazone system control panel is utilized in a stand-alone type
of installation. Either a set of 10 or 18 relays can be selected
from the 50RLP model nomenclature in digit 9 to control either
10 or 18 zones, respectively. If selected in the model nomencla-
ture, zone control relays are located on the right hand side of the
system control panel. See Fig. 4. See Fig. 5A-5C for wiring.
primary power to the power switch and convenience outlet in
the field. Transformers include a manual reset button for reset-
ting the circuit breaker. Control transformers are located on the
bottom half of the system control panel. Specifications for the
control transformers are as follows:
Primary:
120/208/240 vac
Secondary: 24 vac
Frequency: 60 Hz
MOUNTING RAILS AND WIRING DUCT — All exposed
panel wiring is low voltage. Line voltage wiring to the control
transformers, control circuits for pumps, cooling tower fans,
and boilers is factory-installed in conduit, using wiring duct,
and on mounting rails.
CONTROL TRANSFORMERS — Control transformers are
supplied with the Aquazone system control panel and are wired
to the power switch and convenience outlet. The control
transformers provide power to the nominal 24 VAC circuit in
Aquazone system control panel. The contractor will supply the

POWER RECEPTACLE — A power receptacle is provided
in the Aquazone™ system control panel and is located in the
bottom left corner. Specifications for the power receptacle are
as follows:
provide more water. When solenoid valves close, the system
pressure rises, which results in the variable frequency drive
slowing down to allow the pump to provide less water.
WATER FLOW SWITCH — A factory-provided water flow
switch is included with the Aquazone system control panel and
must be field-installed in the water loop piping. The flow
switch is connected to the control panel by a cable with a
watertight connector. This device uses a triac output that cannot
be connected directly to the Main Base Board. Therefore, a
control relay is used to signal the Main Base Board that loop
water flow is detected. The switch contains a fifteen-turn
adjustment potentiometer, to be used to adjust the set point in a
range of 3 to 60 cm/sec. The factory set point is 20 cm/sec.
Power: 120 vac
Rating: 15A @ 120 vac for receptacles
15A @ 120 vac for switch
250 V for fuse
WATER TEMPERATURE SENSORS — Two water tem-
perature sensors and thermowells have been provided with the
Aquazone system control panel. The first sensor is utilized to
read loop supply water temperature, such that the system
control panel can adjust heat rejection and heat addition
equipment to maintain the loop temperature based on user
input. The second sensor may be installed to monitor return
loop water temperature. The active sensing element is a highly
stable precision thermistor material accurate to within ± 0.36 F.
The temperature range of the sensor is 10 F to 230 F.
The potentiometer switch may be adjusted down to zero
velocity (no flow) or above 60 cm/sec, however operation
in those ranges may not be linear or reliable.
WATER PRESSURE SENSOR — A water pressure sensor is
provided with the Aquazone system control panel with variable
speed pumping only, and is utilized to operate variable frequen-
cy drives for system pumps. The water sensor senses system
pressure and the pressure is sent to the system control panel.
The Aquazone system control panel speeds up or slows down
the variable frequency drive to control the pump in order to
keep the system at the correct pressure.
When a variable frequency drive is used for system pump-
ing, the Aquazone water source heat pumps are typically
furnished with a factory or field-mounted solenoid valve that
allows water to flow though the heat pump. When solenoid
valves open, the system pressure drops, which results in the
variable frequency drive speeding up to allow the pump to

PREMIERLINK™ CONTROLLER INPUTS AND OUT-
PUTS — When PremierLink controllers are factory mounted
with water source heat pump equipment to implement a CCN
system installation, the inputs and outputs are shown in Table 3.
CONNECT POWER — The Aquazone™ system control
panel requires an uninterrupted 110-v, single-phase, 60 Hz
power supply. All field wiring must comply with all local and
national fire, safety and electrical codes. It is recommended
that the power supply be separate from the power source
supplying the water source heat pumps. The Aquazone system
control panel is internally fused and a power switch is located
inside the enclosure. Supply power to the Aquazone system
control panel through the convenience outlet in the bottom left
hand corner of the Aquazone system control panel. Do not
apply power until all connections have been made and voltage
supply has been verified. Ground in accordance with NEC and
local electrical codes. Connect the dedicated ground wire to the
position in relationship to the main supply line and use shield
cable to protect from any electrical interference.
CONTROL WIRING — Low voltage wiring for the Aqua-
zone system control panel is shown in Fig. 8.

standard pipe tee (Thredolet fitting) or reducing fitting, with at
least three pipe diameters straight run upstream and down-
stream of the switch. Wire sensor to terminals SDP. See Fig. 8.
Install Thermostat, Sensors and Switches — In
all installations, the loop supply water temperature sensor and
water flow switch must be installed in the field. The water
pressure sensor is used to sense water system pressure to
operate in conjunction with pump variable frequency drives.
A thermostat is used in stand-alone systems. A space tempera-
ture sensor is used in conjunction with water source heat
pumps provided with PremierLink™ controllers. Refer to the
accessory installation instructions literature provided with each
accessory that is used for accessory installation instructions.
Install Loop Water Flow Switch — Install the loop
water flow switch on the discharge side of the circulating
pump(s) in a common supply main so that total system flow
rather than individual pump(s) flow is detected. The flow
switch must be placed in a vertical position and must match the
actual water flow direction with flow switches direction indica-
tors. Seal the switch fitting with Teflon tape and insert in a stan-
dard pipe tee or reducing fitting, with at least three pipe diame-
ters straight run upstream and downstream of the switch.
NOTE: All thermostats, sensors, and switches are field-
installed accessories.
Electrical connection can be made to the switch. Two wires
should be run to the switch for 24 VAC power. The switch is
supplied with wire leads for connection to the FLOW terminal.
When power is supplied to the device, a warm-up period is
initiated. During this period, the right green LED will be lit.
Each LED to the left is successively lit until the farthest left red
LED is lit. Each LED will be turned off when the next is lit.
The warm-up period may take up to 30 seconds.
Install Loop Water Supply and Return Tem-
perature Sensors — Install the water loop supply sen-
sor in the main water supply, located before the water source
heat pumps. Install the water loop return sensor in the return
water piping from the water source heat pumps. The sensors
must be inserted fully into an immersion well (provided). Seal
immersion well threads with tape and install into pipe tee or re-
1
ducing fitting. The well screws into a /2-in. NPT saddle (or
Thredolet fitting) furnished by the installing contractor. Screw
the sensor into the well via the 1/8-in. NPT brass fitting. Termi-
nate wiring with butt splice or soldering. Wire nuts are not rec-
ommended. Use full 8 ft of lead length provided to avoid mois-
ture migration up the wire. Wire the supply sensor to terminals
SSWT. Wire the return sensor to terminals SRWT. See Fig. 8.
Sensors may be located in any position in relationship to the
main supply line. Use shield cable to protect from any electri-
cal interference.
When flow is detected, a red LED at the far left will be lit.
With increasing flow, successive red LEDs will be lit. When
the switch determines sufficient flow is present, the amber
LED lights indicating the output has closed. This is not an indi-
cation of minimum flow. As flow increases, the first green
LED will be lit. Each successive green LED indicates greater
flow. The switch closure does not indicate minimum flow for
the machine. With one green LED lit, minor fluctuations in
water flow may cause nuisance alarms. Additional green LEDs
indicate higher flow rates, and can avoid the nuisance alarms.
The switch is calibrated to light the amber LED at a fluid
velocity of 0.8 ft/sec (0.24 m/sec). The flow rate will depend on
the nozzle size. See Table 4. See Table 5 for Water Flow
Switch Troubleshooting. If the water flow switch is not work-
ing correctly, refer to Table 5.
Install Loop Water Pressure Sensor — Install the
pressure sensor on the discharge side of the circulating pump(s)
in a common supply main so that total system pressure rather
than individual pump(s) flow is detected. The pressure sensor
must be placed in a vertical position and must match the actual
water flow direction with flow switch direction indicators. Seal
the switch fitting with Teflon tape and insert in a 1/4-in.

PROBLEM
SOLUTION
No display or output from the flow sensor
Check for 24 VAC across pins 1 and 3. These are small pins and caution should
be used when measuring the voltage in the harness so as not to damage the connector.
Check flow switch pin connections for damage.
Check for air in the chilled water system.
Check for 24 vac across pins 1 and 3. These are small pins and caution should be used
when measuring the voltage in the harness so as not to damage the connector.
Flow sensor indicates zero flow
when flow is present
Check for fouling on the sensor switch, which could inhibit the dissipation of heat from the probe.
Consider replacing the flow switch. The switch might be out of calibration,
the internal heater may have been damaged by extreme temperatures, pressure
or vibration, or mechanical damage to the tip of the device may have occurred.

Check for 24 vac across pins 1 and 3. These are small pins and caution should
be used when measuring the voltage in the harness so as not to damage the connector.
Low voltage can lead to less heat generated by the internal heater.
Consider replacing the flow switch. The switch might be out of calibration, the internal
heater may have been damaged by extreme temperatures, pressure or vibration, or
mechanical damage to the tip of the device may have occurred.
Connect to CCN Communication Bus — The
Aquazone™ system control panel primary controller connects
to the bus in a daisy chain arrangement. Negative pins on each
component must be connected to respective negative pins and
likewise positive pins on each component must be connected to
respective positive pins. The controller signal pins must be
wired to the signal ground pins. Wiring connections for CCN
must be made at the 3-pin plug. See Fig. 9.
At any baud (9600, 19200, 38400 baud), the number of
controllers is limited to 239 devices maximum. Bus length may
not exceed 4000 ft, with no more than 60 total devices on any
1000-ft section. Optically isolated RS-485 repeaters are
required every 1000 ft.
START-UP
LID Power Up Display — When power is applied to
the Aquazone System Control panel, the red LED on the top
front of the processor module will flash at a rapid pace (about
twice a second) for the first 20 seconds. This rapid flash will
then be replaced by a slower pace of about once per second.
The green LED below the red LED will start flashing. This
LED indicates input/output communications for accessory input
output modules and the LID display.
The first six red LEDs on the controller will light.
The yellow LED will flash when the controller is broadcast-
ing CCN messages to a laptop or other computer.
NOTE: Carrier device default is 9600 baud.
The LID display will show the controller identification,
time and date as shown below.
COMMUNICATION BUS WIRE SPECIFICATIONS —
The CCN Communication Bus wiring is field-supplied and
field-installed. It consists of shielded three-conductor cable
with drain (ground) wire. The cable selected must be identical
to the CCN Communication Bus wire used for the entire
network. See Table 6 for recommended cable.

DEFAULT SCREEN — Figure 10 shows a LID. This screen
provides the user with the 24-character controller name and the
controller’s current time, date, and alarm status. This screen
appears when the LID is powered up and communicating with
the Aquazone System Control Panel Controller or there is no
keyboard activity for10 minutes.
KEYPAD AND DISPLAY — The LID consists of a keypad
with 8 function keys, 4 operative keys, 12 numeric keys (0 to
9, ., and -) and a two-line, alphanumeric liquid crystal display
(LCD). Each line on the LCD can display up to 24 characters.

LID Operation — The Local Interface Device (LID) is a
CCN operator interface that gives the user the capability to
view and modify all configuration and service data for the
Aquazone System Control Panel Controller. The LID also
gives the user the capability to override all point display and
maintenance data.
Clear — performs three operations:
CLEAR
• Cancels a data entry before the user
presses Enter, thus leaving the current
value unchanged.
• Returns a forced point to automatic
control.
• Redisplays the previous menu level.
Enter — performs two operations:
MENU STRUCTURE — The LID operates on a hierarchy of
four levels (menus).
The top level contains the LID’s major functions. Each
function has a corresponding key on the LID. For an explana-
tion of each function key, refer to Table 7.
The second level separates the major functions (items) into
types with corresponding type numbers that can be used for
quick access.
The third level gives the user the capability to access each
occurrence of an item. For example, the application may
require two DO — Analog Comparison algorithms. Thus, the
Aquazone System Control Panel Controller would have two
occurrences of the DO — Analog Comparison algorithm.
ENTER
• Selects the displayed item, thus displaying
either its maintenance or configuration
data, depending on whether the user is in
the Status mode or the Edit mode.
• Accepts the value entered in a configuration
decision as new configuration data or as a
force.
Down arrow — displays the next configured
item or decision. When the last configured
item or decision is displayed, the LID
re-displays the first configured item or
decision. For example, when the user presses
the down arrow key while viewing the last
configuration decision of an algorithm, the LID
re-displays the first configuration decision.
Up arrow — Displays the previous configured
item or decision.
The fourth level gives the user the capability to access main-
tenance and configuration data associated with the selected
occurrence of the item.

VIEWING MODES — The user can view items in either the
Status (maintenance) mode or the Edit (configuration) mode.
Status Mode — When the user first powers up the LID, it
displays the Aquazone System Control Panel Controller items
in the Status (maintenance) mode. The user may view the
current value or status of an item in the Status mode without
actually logging on to the Aquazone System Control Panel
Controller. Knowing the current values or status of items can
be useful when troubleshooting. For example, the user could
determine if a point was forced.
Algorithm — gives access to maintenance
and configuration data for AO, DO, and global
algorithms. It also gives access to BEST ++™
custom programs.
Edit — gives the capability to switch from
Status mode to Edit (configuration) mode for
the selected item. (EXPN is not used in
conjunction with the Aquazone System
Control Panel Controller.)

When the lead output is at 100% and the set point is not
being maintained, the lag output modulates to produce staging
from another two or four stage output transducer.
The value output by each analog output is determined by a
PID calculation of leaving water temperature versus the system
low leaving water temperature set point.
In the event that the system low water temperature set point
cannot be maintained and is exceeded by a defined Hysteresis,
the boiler outputs will go to maximum output, the system water
source heat pumps will stop heating, and the system pumps
will circulate water until the system temperatures are returned
to the normal range. System heating will then be allowed to
continue.
WATER CIRCULATION — When operational mode is de-
termined by one of the 18 occupancy schedules, one of the 18
network or global schedules, or occupancy overrides, then the
system pumps are put in operational mode. Also, if one of the
system enable outputs is forced on, then the system pumps are
put in operational mode.
If the remote occupancy input is detected, then the pumps
are put in operational mode and all 18 schedules overridden to
on. This energizes all 18 system enable outputs.
The pump control type is configured as either variable flow
or constant flow. When the pumps are in operational mode, the
pump speed output values are determined in one of two ways:
1. In constant flow mode, the desired output (one or two) is
ramped to 100% to turn the pumps on in a lead/lag
fashion, based on run time.
2. In variable flow mode, both outputs are determined by a
Proportional Integral Derivative (PID) calculation, which
controls the system pressure set point.
Whenever the runtime of the lead pump exceeds the
runtime of the lag pump by 50 hours or more, then the pump
with the lesser runtime will become the lead pump.
If the lead pump output is at 100% and the loop water flow
input detects no flow, then the lag pump will be put to 100% to
start the lag pump. Both outputs will stay at 100% as an indica-
tor that the lead pump did not start.
At each subsequent start-up, the lead pump will be tried
again. If both pumps are commanded to 100% and no flow is
detected, then the pumps will be forced off. To restart the sys-
tem, a pump must be energized manually or the flow switch
must be overridden to indicate flow. The lead pump will start if
there is a demand for system circulation.
Sequence of Operation
HEAT REJECTION — When the system pumps are operat-
ing and there is flow to the system, heat rejection control
compares the system supply water temperature to the high set
point in the system loop temperature set points.
If the system supply water temperature approaches the high
set point, the controller commands the heat rejection outputs to
hold the system supply water temperature as close as possible
to the high set point.
If the system return water temperature drops below the
system high water temperature set point minus a hysteresis
value the heat rejection, outputs are disabled.
When the cooling tower output control type is set to
“variable,” the heat rejection outputs are calculated using a PID
calculation based on the system high temperature water set
point. Both outputs will modulate together.
When the heat rejection control type is set to “staged,” the
outputs will be modulated in a lead/lag configuration. The
modulating signal of the lead output will control a transducer
of two or four stages.
When the lead output is at 100% and the set point is not
being maintained, the lag output will be modulated to produce
staging from another two or four stage output transducer.
The value output by each analog output is determined by a
PID calculation of leaving water temperature versus the system
high leaving water temperature set point.
In the event that the system high water temperature set point
cannot be maintained and is exceeded by a defined Hysteresis,
the heat rejection outputs will go to maximum output, the
system water source heat pumps will stop cooling, and the
system pumps will circulate water until the system tempera-
tures are returned to the normal range. System cooling will
then be allowed to continue.
HEAT ADDITION — When the system pumps are operating
and there is flow to the system, boiler control compares the
system supply water temperature to the low set point in the
system loop temperature set points.
If the system supply water temperature approaches the low
set point, then the controller commands the boiler outputs to
hold the system supply water temperature as close as possible
to the low set point.
If the system return water temperature rises above the
system low water temperature set point plus a Hysteresis value,
the boiler outputs are disabled.
In the event that the pumps have been commanded to
provide water flow but either the flow switch does not indicate
flow or the differential pressure sensor does not indicate pres-
sure is present, then the controller assumes that the pumps have
failed and commands the water source heat pumps to turn off
cooling or heat. The system fans will continue to circulate the
air.
In the event of a system shutdown command, the controller
commands the water source heat pumps to turn off all cooling
and heat sources and circulating fans.
When the boiler output control type is “variable,” the boiler
outputs will be calculated using a PID calculation based on the
system low temperature water set point. Both outputs will
modulate together.
When the boiler control type is set to “staged,” the outputs
are modulated in a lead lag configuration. The modulating
signal of the lead output controls a transducer (two or four
stages).

LOOP WATER FLOW SWITCH — This discrete input is
used to provide a signal that one of the loop water pumps is on.
If both pumps have been commanded to run and no water flow
is detected, then the system water source heat pumps will
run in the fan only mode for DDC (Direct Digital Control)
coordinated heat pump controllers, while the system relays for
thermostat systems will be turned off.
CONFIGURATION
The Aquazone™ System Control Panel contains a Comfort
Controller 6400 programmed using the standard algorithms
and enhanced by BEST++™ custom programming. The
BEST++ Templates for some of the programs have been
removed to prevent field alterations. For other programs,
the templates are included to allow for jobsite customization.
For basic information about the algorithms please refer to the
Comfort Controller Overview and Configuration manual
(808-891). Default configurations are listed later in this section.

down the supply water distribution piping or in a location that
will provide a good reference of the supply water pressure.
This sensor is used to control the speed of variable frequency
drives pumping water to the water source heat pumps. Each
water source heat pump may be equipped with a two position
isolation valve that may be closed when the compressors are
not energized in order to reduce the quantity of water being
pumped through the system.

For example, the default maximum hours difference for
rotation is 50 hours. If the Lead Pump was forced to 2, so that
pump 2 is the lead pump, then the pump 2 runtime hours will
accumulate until the difference between the pump 1 and pump
2 runtime hours becomes greater than 50. The both will reset to
zero and pump 2 will start accumulating again.

GLOBAL SCHEDULE BROADCAST — If desired, the
schedules 1 through 18 in the Aquazone™ system control
panel may be reconfigured to be schedules 65 through 82 (so
that they may be used as global schedules). If this is done, this
configuration must be set to 1. Local inputs for overriding
zones 1 to 18 or the remote occupancy input will then affect the
global schedules 65 through 82. In this condition local override
of individual PremierLink™ controllers will not occur since
the comfort controller does not respond to the command from
any PremierLink controller to override a global schedule. It is
recommended to allow the PremierLink controllers to broad-
cast global schedules.
figuration determines how the tower outputs will be controlled.
If panels were ordered with the stage output transducers, then
tower control type should be set to 0. If the tower outputs will

should be set to 1.

The loop controller comes pre-configured with local schedules
1 through 18. It is also pre-configured with network schedules 65
through 82 in order to receive global schedules broadcast from
PremierLink™ controllers or other networked controllers. See
Network Time Schedule section. This is the recommended
method for using global schedules since a PremierLink controller
(when set up to broadcast a global schedule) will respond to a
schedule override request from another PremierLink controller
that it is broadcasting the global schedule. This allows all
PremierLink controllers following the same global schedule to
enter occupancy override as a group.

OCCUPIED FROM — This field is used to configure the
hour and minute, in military time, that the mode for the
PremierLink™ controller will switch to occupied.
Network Time Schedule — The network time schedule
allows the occupancy schedule in another device on the CCN
to control the Aquazone™ system control panel’s occupancy
state.
Each time the occupancy schedule on the controlling device
changes to occupied, the controlling device broadcasts an
occupancy flag over the CCN. To receive an occupancy flag,
a network time created. Up to 18 network time schedules are
configured. The schedules are sequentially named OCCPC65E
to OCCPC82E, however Service Tool or Building Supervisor
software can be used to modify the names up to OCCPC99E.

Holiday Schedules — A Holiday schedule allows the
user the capability to specify days of the year (holidays) on
which the Aquazone system control panel will follow the
holiday time schedule instead of the normal time schedule for
that day. Holiday time schedules are normally used to program
a weekday in unoccupied mode for the entire day since the
building will be empty during a holiday.
There are 16 different holiday schedules that can be created.
Holiday schedules can also last more than one day, as long as
the days are consecutive.
Holiday schedules must be configured on the time and date
broadcaster element on the CCN. If the Comfort Controller on
the Aquazone system control panel is the broadcaster, it will
send holiday status to all other system elements on the CCN. If
the Comfort Controller is not the broadcaster, do not configure
the holiday schedules for it, as they will not be used.
