Component Location and Wiring 

Considerations

Locating Bryant 3-Zone System

All  wiring  is  connected  back  to  the  Bryant  3-Zone  System.  Select  a

location near the furnace or fan coil where wiring from each thermostat,

each damper actuator, and the equipment itself can come together easily.
The Bryant 3-Zone System is approved for indoor use only and should

never be installed with any of its components exposed to the elements. It

may be installed in any area where the temperature remains between 32°

and 158°F, and there is no condensation. The cover must be installed to

prevent  damage  from  other  sources.  Do  not  locate  where  it  will  be

accessible to children. Remember that wiring access is likely the most

important consideration. 

Wiring Considerations

• All wiring in the Bryant 3-Zone system may be unshielded

• Ordinary thermostat wire is ideal

• Use 22 gage or larger for normal wiring

• Lengths over 100 ft should use 20 gage or larger wire

• Each damper actuator required 3 conductors

• The  connection  to  thermostat  and  equipment  (furnace  or  fan  coil)

could require as many as 8 conductors for a multi-state installation

• The 

Leaving  Air  Temperature  (LAT)

    and 

Heat  Pump  Temperature

(HPT)

-(used with heat pumps only) sensors require 2 conductors each

• Cables with excess conductors are acceptable

Step 1 – Mounting the Bryant 3-Zone System

The  Bryant  3-Zone  System  can  be  mounted  in  either  vertical  or

horizontal  position  near  the  HVAC  system  inside  the  home.  It  is

designed so that wires can enter it from behind, above, or below. Plan

wire routing before mounting.

Fig. 2 – Mounting the System

1. Remove  the  front  cover  from  the  base  and  use  the  base  as  a

template to mark drilling locations on the wall, stud , or roof truss.

2. Mount using 4 screws (and wall anchors) provided. (See 

Fig. 2

.)

3. Level for appearance and tighten screws.

Step 2 – Install Thermostats in each desired Zone 

Location

1. Install each thermostat according to the manufacturer’s instructions

in their designated Zone location.

2. Connect the thermostats wires to their respective Zone designation

on the right side of the the 3-Zone Panels. (See 

Fig. 3

).

Step 3 – Install Zone Dampers

Each  damper  has  3  connections: 

Close  (CLS)

Open  (OPN),

  and

Common (COM)

. Find the connection points along the lower left side

of  the  3-Zone  Control.  Suggested  colors  are  CLS  =  RED;  OPN  =

GREEN, COM = WHITE. Field label and make the connections at the

dampers  and  at  the  3-Zone  Control.  Be  careful  not  to  cross  zone

numbers.
If  duct  work  required  multiple  dampers  for  a  single  zone,  up  to  5

dampers may be wired in parallel and may be installed in any position.

WARNING

!

ELECTRICAL SHOCK HAZARD

Failure to follow this warning could result in personal injury or death.

Turn off  unit  before  routing  control  wiring or any  service  operation.

Remember, there may be more than one power supply to unit.

CAUTION

!

EQUIPMENT DAMAGE HAZARD

Failure to follow this caution may result in equipment  damage.
To prevent possible damage to Bryant 3-Zone System, do not mount

control on plenum, duct work, or flush against furnace.
