Features and

Benefits

The UniTrane^®fan-coil meets the

• Piping is factory assembled, mounted

and tested. Units are also available

without piping. Reheat coil piping is

available on 2-pipe units with hot water

reheat coils and either a fan speed

switch or Tracer ZN.520.

• Factory piping options include intercon-

necting piping, control valves, and end

valves. Deluxe piping also has unions

and a strainer.

• Control options range from a simple fan

speed switch to a DDC controller that

can tie into a Tracer Summit^®building

automation system.

• An 8-inch (20 cm) extended end pocket is

an available option on the piping end of

cabinet style units.

• Controls are wired with a 24 VAC

transformer to keep only a single

source power connection requirement

to the unit.

• All wall-mounted zone sensors require

only low voltage control wiring from the

device to the unit control box. (No line

voltage.)

standards of today’s market, as well as

the anticipated needs of tomorrow’s

market. The tradition that company

founder Reuben Trane began 60 years

ago continues with the latest generation

of fan-coils from The Trane Company.

The UniTrane^®fan-coil is the leader in

these key areas:

• Indoor Air Quality (IAQ)

• Controls

• The Tracer^®controls family introduces

the latest in control technology with the

ZN.010, ZN.510, and ZN.520 controllers.

• The controller automatically determines

the unit’s correct operating mode (heat/

cool) by utilizing a proportional/integral

(PI) control algorithm to maintain the

space temperature at the active

setpoint, allowing total comfort control.

• Entering water temperature sampling

eliminates the need for inefficient

bleedlines to sense automatic

changeover on two-pipe changeover

units.

• The random start-up feature helps

reduce electrical demand peaks by

randomly staggering multiple units at

start-up.

• Occupied/unoccupied operation allows

the controller to utilize unoccupied

temperature setpoints for energy

savings.

• Flexibility

• Quality

• Serviceability

Today’s HVAC market is concerned with

issues such as indoor air quality (IAQ) and

CFCs that demand a change in HVAC

products. In addition, renovation has

overtaken new construction in the fan-coil

market—demanding a design that caters

to renovation issues. Trane is concerned

with these issues, too. That’s why we

designed the UniTrane fan-coil as an

integral part of the company’s system

solutions with standard IAQ-related

features that fully comply with

• Slope-top vertical cabinet units are also

available for school and dormitory

applications to prevent items from

being placed on top of the units.

Quality

• Coils and piping packages are air and

leak-tested before mounting on the fan-

coil.

• Coil piping connections are also air and

leak-tested after mounting on the unit.

• All control end devices and moving

components (fans and motors) are

computer-tested after units are

complete.

ASHRAE 62.

IAQ Design

• Closed-cell insulation is standard on all

units to help prevent fiberglass in the

airstream.

• Warm-up and cool-down energy

features are standard with Trane

controls.

Serviceability

• The main and auxiliary drain pans are

constructed of a noncorrosive engi-

neered plastic (ABS and CyColac T).

• The main and auxiliary drain pans are

positively sloped in every plane to

assure proper drainage and help

maximize protection from microbial

growth.

• The drain pans are removable for

cleaning.

• Easy filter access encourages frequent

changing.

• The auto-economizer damper option

allows free cooling and ventilation to

help comply with ASHRAE 62—and

save energy and operating costs.

• UniTrane fan-coils have a blow-thru

design. Low vertical units are draw-

thru.

• Filters are easily removable and

changed without removing the front

panel on vertical cabinet units.

• Motors are easy to disconnect from the

fan board, allowing easy service.

• The main and auxiliary drain pans are

easily removable and wipe clean with a

wet cloth.

• Continuous fan or fan cycling is available

with ZN.010 or ZN.510.

• Monitor unit operation using Tracer^®

Summit building management system

with ZN.510 or ZN.520.

• To customize unit control, Tracer Summit

or Rover^™software will allow field

modification of ZN.510 and ZN.520

default settings. For ZN.010, use Rover

to field modify default settings.

• Maximize fan-coil system efficiency with

free cooling economizers and modulat-

ing valves on units with ZN.520.

• The manual output test function is an

invaluable troubleshooting tool. By

simply pressing the test button on the

Tracer^®ZN.510, ZN.520, or ZN.010;

service personnel can manually

exercise outputs in a pre-defined

sequence.

Flexibility

• Two, three, and four-row coils allow

greater design flexibility in two and

four-pipe systems.

• One-row steam or hot water reheat

coils for dehudification on units with

ZN.520 controls.

• Fan motors are available for either high

static (0.4-inch external static pressure)

or free discharge applications.

Controls

• All controls are factory-mounted and

tested to minimize field setup.

detailed description of each of the piping

components. Following this section are

additional illustrations and specifications.

each for both chilled and hot water. A label

identifying connection points clearly

marks both chilled and hot water on

every unit.

Factory-Installed Piping

Packages

UniTrane^®fan-coils have standard piping

packages available as a factory built and

installed option, for the main coil. Piping

package options are also available for the

hot water reheat coil on two-pipe units

equipped with either a fan speed switch

or Tracer^®ZN.520 controller. Factory built

assures all piping packages are fully

tested under water for leaks and are built

within strict tolerances. Factory-installed

means that chilled and hot water pipes

are the only field connections required.

The installer doesn’t have to sweat

connect piping packages onto coil

connections in a tight end pocket. Field

connections are brought to a point near

the exterior of the unit for easy access.

All piping and components are located to

allow condensate to drain into the

auxiliary drain pan. Insulation of the

factory piping package is not required.

However, all field connections should be

insulated to prevent condensation from

missing the auxiliary drain pan.

Piping System/Placement

Deluxe or Basic Piping Package

The basic piping package includes only

the main components of the piping

package: interconnecting piping, control

valves, and end valves.

Factory piping systems are available for

either two or four-pipe systems with right

or left hand connections. Four-pipe

systems have both the heating and

cooling connections on the same side of

the unit. A simple coil connection (a unit

without a piping package) is also avail-

able in either a right or left hand configu-

ration for those applications requiring

field piping.

The deluxe piping package also includes

a strainer on the entering water pipe and

unions at the coil connections along with

the basic components. The strainer body

is cast brass construction, with a stain-

less steel mesh strainer that is easily

removed for cleaning. The unions are

forged brass construction and close with

a minimum amount of effort.

Interconnecting Piping

Interconnecting piping refers to the

copper piping which is attached to the coil

connections and to which all other

components (control valves, end valves,

etc.) are attached. Piping is ¹/ ” nominal

OD copper. Two-pipe piping ²extends near

the unit exterior to one inlet and one

outlet connection.Four-pipe units have

two sets of piping that extend near the

unit’s exterior—one inlet and one outlet

End Valves

Each piping package includes a ball valve

for the entering water pipe and one of the

following end valves on the leaving water

pipe: ball valve, manual circuit setter, or

an auto circuit setter. These valves serve

as the field connection points on all

UniTrane piping packages.

Piping Package Components

UniTrane piping packages consist of a

variety of components for each applica-

• Ball Valves

Ball valves, also known as stop or end

valves, allow the unit to be cut off for

service purposes. These valves have a

two-inch handle that rotates 90 degrees

to a fully open position. The valve body is

cast brass, and the ball is polished brass

with a Teflon seat. Ball valves are

available as end valves on both the

entering and leaving water pipes.

setter is shown on a horizontal concealed unit.

measurement of the pressure drop

temperature through the valve.

In lieu of a ball valve on the leaving water

pipe, a manual circuit setter, also known

as a manual flow control valve, acts as

both a flow setting device and a stop

valve. This valve allows water flow

through the fan-coil unit to be set quickly

and accurately.

Control Valves

Piping packages are available with or

without control valves. All control valve

options are factory mounted and wired

to the UniTrane^®fan-coil controls.

• Two-Way Modulating Valves

These valves modulate the water flow

through the coil in response to a signal

from the Trane controller. All modulating

valves are three-wire floating point equal

percentage valves. The modulating

valves are factory mounted in the leaving

water pipe downstream of the coil.

• Two-Way/Two-Position Valves

The manual circuit setter includes

Schrader ports in the valve body. These

ports are used to measure the pressure

drop across the valve. This pressure

drop can be compared to factory

supplied curves that relate the pressure

drop to a specific flow rate. This valve

also has a memory stop so the correct

setting can be found quickly.

These valves will either fully open or

close in response to a 24VAC signal from

the Trane controller. Main control valves

are direct-acting valves, while the

auxiliary valves are reverse-acting. All

control valves are factory mounted in the

leaving water pipe downstream of the

coil. Some means of relieving pump

head pressure should be accounted for

when two-way valves are selected.

Normally open or normally closed valves

are available.

• Three-Way Modulating Valves

These valves modulate the water flow

through the coil in response to a signal.

Three-way valves allow water that is

directed through the coil to mix with

water that is directed through the bypass

line. This mixture exits through the leaving

water pipe. All modulating valves are

three-wire floating point equal percent-

age valves. The modulating valves are

factory mounted in the leaving water pipe

downstream of the coil.

Auto Circuit Setter

An auto circuit setter is an automatic flow

control device available on the leaving

water pipe. The auto circuit setter

includes a cartridge within the valve

body that is sized to allow a specific flow

rate through the coil. This valve sets flow

through the coil without any action

required by a system piping balancer.

The auto circuit setter is available on the

leaving water pipe with a ball valve.

• Three-Way/Two-Position Valves

These valves will either allow full water

flow through the coil or divert the flow

through a bypass line. The valves

respond to a 24VAC signal from the

Trane controller. Main control valves are

direct acting valves, while the auxiliary

valves are reverse-acting. All three-way

valve packages include a balance fitting

The auto circuit setter also includes two

P/T’s plugs in the valve body to allow

Find the ∆P across the water coil. Refer to

the ARI performance table to determine

the ∆P across the water coil (or use

TOPSS™ selection program). The water

pressure drop is found to be 7.0’ (20.9

kPa) of water at a flow rate of 3.74 gpm.

This converts to a pressure drop of 3.03

psig (1.0 feet of water = 0.4328 psig.)

Calculate the Cv of the water coil.

Cv = GPM/Square root ∆P.

Cv = 3.74/Square root 3.03

Cv = 2.15

Therefore, the valve with the Cv of 2.5

should be selected since it has the Cv

which is closest to the Cv of the water

coil. The following tables illustrate

possible valve selections at ARI condi-

tions for horizontal concealed units with a

high static motor and vertical cabinet

units with a free discharge motor.

Note: Do not use these tables for any

applications other than vertical cabinet or

horizontal concealed units at ARI condi-

tions.

1. CFM = Cubic feet per minute

2. TMBH = Total capacity (MBH)

3. GPM = Gallons per minute

4. WPD = Water pressure drop (feet of water)

5. Q/ITD = MBH (kW)/(Entering water temperature - Entering air temperature) when ∆T and GPM (L/s) remain constant. To determine heating capacities at a different entering water

temperature or entering air temp, compute the new ITD and multiply it by the Q/ITD shown.

6. Medium and low speed capacities are approximately 80 percent and 60 percent respectively of the high speed capacity.

7. High static motors need the appropriate length of duct to prevent poor acoustical applications.

Performance

Data

ARI cooling performance is based on 80/67 F (27/19 C) entering air temperature, 45 F (7 C) entering chilled water temperature with a

10 F (5.5 C) DT.

Heating performance is based on 70 F (21 C) entering air temperature, 180 F (82 C) entering hot water temperature with a

30 F (17 C) DT.

All performance measured on high speed tap, 115 V, zero ESP, with a throwaway filter. See page 18 for performance groupings.

Control Options

UniTrane^®fan-coils are available with four different control options:

• Manual three-speed fan switch

• Tracer ZN.010

• Tracer ZN.510

• Tracer ZN.520

Manual Fan Mode Switch

Model Number Digit 30 = A and Digit 31 = D or K

The manual fan mode switch is available for fan-coil units that do not have Trane

factory-mounted control packages. This four-position switch (off, high, medium,low)

allows manual fan mode selection and is available unit or wall mounted. The unit-

mounted option (Digit 31 = D) operates on line voltage. The wall-mounted option (Digit

31 = K) is low-voltage and has three 24 volt relays using a factory-wired transformer

and relays to control the fan motor.

Tracer^®Controls

The Tracer family of controllers, ZN.010; ZN.510; and ZN.520, offer the combined

advantages of simple and dependable operation with the latest Trane-designed

controller. Standard control features include options normally available on more

elaborate control systems. All control options are available factory-configured or can

be field-configured using Rover^™service software. For more detailed information, refer

to the Trane publication, CNT-IOP-1 or CNT-IOP-2.

Fan Speed Switch

Tracer ZN.010

Model Number Digit 30 = E

Tracer ZN.010 is a stand-alone microprocessor controller.

Tracer ZN.510

Model Number Digit 30 = F

ZN.510 can be used as either a stand-alone or communicating microprocessor

controller.

Tracer ZN.520

Model Number Digit 30 = G

The ZN.520 controller can be used in a stand-alone application or as part of a Trane

Integrated Comfort^™System (ICS).

In the stand-alone configuration, ZN.520 receives operation commands from the zone

sensor and/or the auto changeover sensor (on auto changeover units). The entering

water temperature is read from the auto changeover sensor and determines if the unit

is capable of cooling or heating. The zone sensor module is capable of transmitting the

following information to the controller:

ZN.010 Control Board

• Timed override on/cancel request

• Zone setpoint

• Current zone temperature

• Fan mode selection (off-auto-high-med-low)

For optimal system performance, fan-coil units can operate as part of an Integrated

Comfort™ System (ICS) building automation system controlled by Tracer Summit^®.

The controller is linked directly to the Summit control panel via a twisted pair communi-

cation wire, requiring no additional interface device (i.e., a command unit). The Trane

ICS system can monitor or override ZN.520 control points. This includes such points as

temperature and output positions.

Rover^™Service Software

ZN.510 Control Board

This windows-based software package option allows field service personnel to easily

monitor, save, download, and configure Tracer controllers through a communication

link from a portable computer. When connected to the communication link, Rover can

view any Tracer controller that is on the same communication link.

meet precise capacity requirements,

while minimizing fan speed (motor/

energy/acoustics) and valve position

(pump energy/chilled water reset). As the

capacity requirement increases at low

fan speed, the water valve opens. When

the low fan speed capacity switch point is

reached, the fan switches to medium

speed and the water valve repositions to

maintain an equivalent capacity. The

reverse sequence takes place with a

decrease in required capacity.

Control Features

Determination

The following control functions are

standard features on units with Tracer

ZN.010, ZN.510, or ZN.520.

The controller automatically determines

whether heating or cooling is needed—

based on space and system conditions.

Utilizing a proportional/integral (PI) control

algorithm to maintain the space tempera-

ture at the active heating or cooling

setpoint. The controller measures the

space temperature and active setpoint

temperature to determine the unit’s

heating or cooling capacity (zero to

100%).

Economizing Control (ZN.520)

With the controller configured for

Entering Water Temperature Sampling

Function

economizing control, it will calculate the

required cooling capacity every ten

seconds and modulate the damper option

open to the calculated position. If the

setpoint is not satisfied, the damper will

continue to open until the setpoint

condition has been met or the damper is

100 percent open. If this still does not

satisfy the setpoint, the cooling valve

option will begin to open and try to satisfy

the load requirements. Once capacity

exceeds the load requirements, the valve

will begin to close until the setpoint has

been reached or the damper reaches its

minimum position, which is field-adjust-

able. This option uses a three-wire,

floating point damper actuator.

A system that uses a two-way control

valve option might not sense the correct

entering water temperature during long

periods when the control valve is closed.

If the demand for heating or cooling does

not exist for a long period, the entering

water will eventually approach ambient

temperature.

Occupied/Unoccupied Operation

The occupancy input utilizes a binary

switch (i.e. motion sensor, timeclock, etc.)

that allows the zone sensor to utilize it’s

unoccupied internal setpoints.

Using the entering water temperature

sampling function, the controller pro-

vides accurate two-pipe system

changeover—without sacrificing the

benefits of two-way control valves. Also,

it eliminates inefficient bleed or bypass

lines that can allow unnecessary

waterflow through the system.

Random Start

This feature randomly staggers multiple

unit start-up to reduce electrical demand

spikes.

A thermistor to sense discharge air is

factory mounted near the discharge

surface of the last coil for use in econo-

mizing and cascade temperature control.

Summit^®can also utilize this temperature

value as a read-only point. Cascade

temperature control uses both the zone

and discharge air temperatures to more

accurately calculate the required unit

capacity.

Warm-up

This function periodically samples the

entering water temperature by opening

the hydronic valve. The valve opens for

20 seconds to allow the water tempera-

ture to stabilize. Then the controller reads

the entering water temperature for up to

three minutes to see if the correct water

temperature is available for the selected

operating mode.

The two-position fresh air damper option

closes during the occupied mode when

the space temperature is three degrees

or more below the heating setpoint

temperature. The damper remains

closed during warm-up until the space

temperature is within two degrees of the

heating setpoint temperature.

Cool-down

The entering water temperature must be

five degrees or more above the space

temperature to allow hydronic heating

and five degrees or more below the

space temperature to allow hydronic

cooling. If the correct water temperature

for the operating mode is available, the

unit begins normal heating or cooling

operation. If the correct water tempera-

ture is not available, the controller closes

the control valve and waits 60 minutes

before attempting to sample the entering

water temperature again.

A thermistor to sense fresh air is factory

mounted at the unit’s fresh air opening for

use in economizer applications or as a

read-only point for Summit. If the fresh air

temperature is a read-only value, it will

not impact the control algorithm. In an

economizer application, a fresh air

The two-position fresh air damper option

the space temperature is three degrees

or more above the cooling setpoint

temperature. The damper remains

closed during cool-down until the space

temperature is within two degrees of the

cooling setpoint temperature.

temperature signal must be provided

either by this thermistor or Summit.

Manual Output Test Function

This feature is an invaluable tool for

troubleshooting a unit. By simply press-

ing the controller’s test button, service

personnel can manually exercise outputs

in a pre-defined sequence.

A factory-mounted thermistor senses

the entering water temperature on

changeover cooling/heating coil units. If

the fan-coil has a factory-mounted piping

package, the sensor is strapped to the

entering water pipe. If the fan-coil does

not have a piping package, the sensor is

coiled in the end pocket for mounting on

customer-supplied piping. This sensor

must detect accurate water temperature

for proper changeover.

Peer to Peer Communication (ZN.510

and ZN.520)

Peer to peer communication allows

multiple units in one space to share the

same zone sensor and provide simulta-

neous heating and cooling. The ZN.510 or

ZN.520 controller can share information

between units on the same communica-

Features

Controls

Water Valve Override

ZN.520 Additional Features

Automatic Ventilation Reset

Using Summit or Rover, the water valve

override function drives all water valves

in every unit fully open simultaneously.

This helps reduce the time required for

waterside balancing.

To ensure proper ventilation rates, the

controller is configured with two fresh air

damper minimum position setpoints for

occupied operation. As the fan speed

changes to low or high, the damper

modulates to maintain the correct

ventilation rate for the space. The

damper position does not change when

the fan speed changes to medium.

Cascade Control

The controller maintains discharge air

temperature using a cascade control

algorithm. The discharge air temperature

is based on the difference between the

space temperature and setpoint. Unit

capacity modulates to achieve the

discharge air temperature.

Fan Status

The ZN.520 controller monitors the fan

output status to determine if the fan is

operating.

Interoperability

The ZN.520 controller can be used with a

Tracer Summit system or on other

control systems that suport LonTalk and

the SCC profile. For more information on

specific inputs and outputs, see the

Installation, Owner, and Maintenance

Manual, UNT-IOM-6.

Filter Maintenance Status

The controller has an adjustable timer

that indicates through Summit or Rover

when filter maintenance is necessary.

Filter maintenance status is based on

cumulative fan run hours.

Dehumidification

When the fan-coil unit is equipped with a

reheat coil and humidity sensor, the

controller will keep humidity levels within

an acceptable range. This feature helps

reduce the risk of microbial growth and

damage to building interiors.

Two-position valve options are available

with either Tracer ZN.010, ZN.510, or

ZN.520. Valves are spring-return type,

sweat connections, and available as

normally open or closed. The valves

respond to a 24V signal and have ¹/₂-inch

sweat connections. The two-way valve

option will either fully open or close. The

three-way valve option allows either full

water flow through the coil or diverts

waterflow through the bypass. If the

control valve loses power, the valve

returns to its de-energized position. All

control valve options are factory installed

in the leaving water piping downstream

of the hydronic coil. The valve actuator is

easily removable for service without

removing the valve body from piping.

Model Number Digits 27 and 28 = X or Y

When using field-supplied valves, this

option allows the controller to be factory-

configured for the normal position of the

field-supplied valve.

Note: The Trane Company does not

recommend wild coil applications.

This option is a three-wire floating point,

spring-return damper actuator and is

factory-wired and mounted to the

damper assembly. When the controller

enables the economizer and the unit is in

occupied mode, the fresh air damper

modulates between its minimum position

A float switch is factory-supplied for field

installation in the auxiliary drain pan to

detect a high condensate water level.

When the float switch rises, the normally

closed input opens a corresponding set of

binary input terminals. This also causes

the fan to disable, and the control valve

and fresh air damper options to close.

Although the float switch will close when

the high condensate level recedes, the

Low vertical units are only available with electric heat in combination with the two-row cooling coil.

Minimum Circuit Ampacity (MCA) and Maximum Fuse Size (MFS) Calculations for

Fan-Coils with Electric Heat

Heater Amps = (Heater kW x 1000)/Heater Voltage

Note: Use 120V heater voltage for 115V units. Use 240V heater voltage for 230V units.

MCA = 1.25 x (heater amps + all motor FLA’s)

MFS or HACR Type Circuit Breaker = (2.25 x Largest Motor FLA) + Second Motor FLA

+ Heater Amps (If Applicable)

HACR (Heating, Air-Conditioning and Refrigeration) type circuit breakers are required

in the branch circuit wiring for all fan-coils with electric heat.

SeeTables ED- 3 through ED-6 for motor FLA’s

Select a standard fuse size or HACR type circuit breaker equal to the MCA.

Use the next larger standard size if the MCA does not equal a standard size.

Standard Fuse Sizes are: 15, 20, 25, 30, 35, 40, 45, 50, 60 amps

Fan-coil electric heat MBH = (Heater kW) (3.413)

Note:

Values for fractional HP’s (kW’s) are approximate values and

not necessarily the actual HP (kW).

Minimum Circuit Ampacity (MCA) and Maximum Fuse Size (MFS) Calculations for

Fan-Coils: (Motors only, No Electric Heat)

MCA = (1.25) x [Largest Motor Amperes (FLA)] + Second Motor Amperes (FLA)

(Size 10 and 12 only)

MFS or HACR* Type Circuit Breaker = 15 Amps for all Fan-Coils without

Electric Heat

(See previous Electrical Data for units with Electric Heat.)

*HACR (Heating, Air-Conditioning and Refrigeration) type circuit breakers are

required in the branch circuit wiring for all size 10 and 12 fan-coils.

Manual Three-Speed Fan Switch

The manual three-speed fan switch is a simple four-position switch (OFF-HI-MED-LO)

which allows fan mode selection.

The fan switch is wall-mounted and controls the fan motor by line voltage.

Off: Fan is turned off.

Hi, Med, Lo: Fan runs continuously at the selected speed setting.

Ball Valves

Ball valves are available as ship-loose components with each unit:

Ball valves, also known as stop or end valves, allow waterflow into the unit to be cut off

for service purposes. These valves have a two-inch handle that rotates 90 degrees to a

fully open position. The valve body is cast brass, the ball is chrome plated brass, and

the seat is Teflon^™. Ball valves are available as end valves for both the entering and

leaving water pipe of field-installed piping. Working pressure is 400 psi (2,758 kPa).

Electrical Data

Electric Heat Features

• All basic series fan-coil units are UL

approved.

• Units require only a single-point electri-

cal connection.

• A unit mounted magnetic contactor(s) is

(are) supplied on all unit voltages.

• A high temperature cutout with auto-

matic reset de-energizes the electric

heat in the event of an overheat

condition.

• When hydronic heating is active, a

lockout sensor will disable the electric

heat.

Electric Heat

Basic series fan-coils with inlet plenums

are available with electric heating coils.

Coil Construction and Location

Electric heat coils are open wire type with

a nickel chrominum element design. All

coils are located in the preheat position.

Power Supply

Units have single-point power since the

electric heating elements operate on line

voltage.

Minimum Circuit Ampacity (MCA) and Maximum Fuse Size (MFS) Calculations for

Fan-Coils with Electric Heat:

Heater Amps = (Heater kW x 1000)/Heater Voltage

Note: Use 120V heater voltage for 115V units. Use 240V heater voltage for 230V units.

MCA = 1.25 x (heater amps + all motor FLA’s)

MFS or HACR Type Circuit Breaker =

(2.25 x Largest Motor FLA) + Second Motor FLA + Heater Amps

HACR (Heating, Air-Conditioning and Refrigeration) type circuit breakers are required

in the branch circuit wiring for all fan-coils with electric heat. See the Electrical Data

section for motor FLA’s.

Note: Select a standard fuse size or HACR type circuit breaker equal to the MCA.

Use the next larger standard size if the MCA does not equal a standard size. Standard

fuse sizes are: 15, 20, 25, 30, 35, 40, 45, 50, and 60 amps
