SAFETY CONSIDERATIONS

Read and follow manufacturer instructions carefully. Follow all local electrical

codes during installation. All wiring must conform to local and national electrical

codes. Improper wiring or installation may damage Thermidistat Control.

Recognize safety information. This is the safety--alert symbol . When you see

this symbol on the equipment and in the instruction manual, be alert to the potential

for personal injury.

Understand the signal words DANGER,WARNING,andCAUTION.These

words are used with the safety--alert symbol. DANGER identifies the most serious

hazards which will result in severe personal injury or death. WARNING signifies a

hazard which could result in personal injury or death. CAUTION is used to identify

unsafe practices which may result in minor personal injury or product and property

damage. NOTE is used to highlight suggestions which will result in enhanced

installation, reliability, or operation.

INTRODUCTION

Bryant’s 7--day, 5/2--day, 1--day programmable and non--programmable Preferred

Series Thermidistat Control is a wall--mounted, low--voltage control which

combines temperature and humidity control in either a single unit or a two--piece

unit. In two--piece configuration, the relays are located near the equipment and a

two--wire connection is used between the Display Module and the Equipment

Control Module. Single--piece installation requires more wiring and results in a

higher profile. The Preferred Series Thermidistat has no need for batteries to store

user--configured settings in memory. During power loss its internal memory saves

settings for unlimited time, and the clock continues to run for at least 24 hours. An

extension of Bryant’s proven line of thermostats; it provides separate setpoints for

heating and cooling in addition to humidification and dehumidification.

In the programmable configuration of the Preferred Series Thermidistat Control,

different heating and cooling setpoints and times are programmable for 4 periods

per day or 2 periods per day. Programming can be done for 7 days per week, 5/2

days per week, or 1 day. The programmable Thermidistat Control can also be user

configured as a non--programmable Thermidistat Control. When operating as

non--programmable, the Thermidistat Control will still have both temperature and

humidity control.

The non--programmable Thermidistat Control features Touch ’N’ Gotsettings for

quick and easy temperature change without complicated programming schedules.

The non--programmable Thermidistat Control will still have both temperature and

humidity control. And, its Touch ’N’ Go technology enables the user to switch

between three different user--configurable settings through intuitive buttons located

just below the display.

INSTALLATION CONSIDERATIONS

Power

This control is powered by 24VAC only. It requires 24VAC (Rh and/or Rc and C

terminals) of the low--voltage transformer to be connected to it for proper operation.

It will not operate without these 2 connections. Rh and Rc are connected via PCB

breakout jumper. See Fig. 1. For applications using two 24VAC transformers, one in

the indoor unit and one in the outdoor unit, connect the common from each to the C

terminal. Connect R from the indoor unit to the Rh terminal. Connect R from the

outdoor unit to the Rc terminal. Then, break jumper on the circuit board. The W and

HUM signals are taken from the Rh power and the G signal is taken from the Rc

power. If Thermidistat Control has been installed in a two--transformer application

that is later changed to a single--transformer installation, installer must install a field

supplied jumper between Rc and Rh. Depending on the installation, up to 14 wires

may be required. Installation as two--piece unit is recommended. Only 2 wires are

required for connection between Display Module and Equipment Control Module.

These two wires (V+ and Vg) do not provide ordinary 24VAC. They carry a

combination of power and communications data that is unique to these products.

Models

There are programmable and non--programmable models for all applications. They

can be configured for AC or HP, 1--or 2--speed compressor, and for Hybrid Heatt

installations, allowing it to be used in place of all Bryant thermostats.

Programmable Thermidistat Controls may be configured as non--programmable if

user desires.

Humidify Equipment and Connections

The humidify output connects directly to 24VAC operated humidifiers. No other

connection or interlock is required. Any of several installer--selectable operating

modes are available.

ELECTRICAL OPERATION HAZARD

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

DO NOT connect furnace HUM terminal directly to Thermidistat

Control HUM terminal. This will bypass furnace safety controls. See

Low Voltage Wiring Diagrams and notes for proper connection.

!WARNING

Dehumidify Equipment and Connections

The dry contact output connects to the dehumidify input on variable--speed

furnaces and fan coils. Additional dehumidification is done by controlling the

compressor. A variety of operating modes are available. The dry contact must be

configured for dehumidification in setup Option 19. See Wiring Diagrams for more

information.

Outdoor Temperature Sensor (TSTATBBSEN01--B)

Outdoor air temperature sensor is included in the box with the Thermidistat Control.

Optimum performance is obtained when an outdoor temperature sensor is used with

the Thermidistat Control. Plan installation so that 2 wires can be run from

Equipment Control Module to an outdoor location, preferably on the north side of

the house or refer to Installation Instructions included with the outdoor temperature

sensor for simplified connection. Sensor can be mounted to outdoor unit and

existing control wires may be used for its connection. Details are provided in sensor

instructions.

Remote Indoor Temperature Sensor

A remote temperature sensor may be used with the programmable model, where it

is desirable to install the Thermidistat Control in a limited access location while

measuring the temperature in the living space. The remote room sensor may be

used as a stand alone or average with local sensor.

Two--Piece Thermidistat Control Configuration

The Preferred Series Thermidistat Control can be installed in one of two

configurations. The control may be installed as a single--piece Thermidistat or it

may be split into two pieces and mounted in separate locations. As a single--piece

unit, all required wiring must be brought to the Equipment Control Module for

connection to the terminal strip. In two--piece configuration, the Display Module

can be mounted in the living space while the Equipment Control Module may be

mounted near the indoor furnace or fan coil. Connection from the display to the

Equipment Control Module requires only two wires. All other control wires are

connected to the Equipment Control Module from the HVAC equipment. This

configuration results in a slimmer display and locates the Equipment Control

Module containing the switching relays away from the main living space where

relay clicking will not be heard.

The model numbers on the Display Module and the Equipment Control Module

(ECM) must match or unpredictable results may occur.

Two--wire pigtail replacement part number is TX--2WR05.

Wiring

For all wiring applications, use 22 AWG or larger wire. Continuous wire lengths

over 100 ft. (30.5 m) should use 20 AWG or larger. Wire lengths are not to exceed

250ft.(76m)perrun.

INSTALLATION

UNIT DAMAGE HAZARD

Failure to follow the recommended wiring practices could result in

damage to the wall control and personal property.

Improper wiring or installation may damage Thermidistat Control.

Check to make sure wiring is correct before proceeding with

installation or turning on power.

CAUTION

Installation Notes:

SNo part of the control should be installed directly outdoors or in a cabin-

et outdoors.

SNever remove the thermostat board from the plastic housing. Doing so

could warp and damage the components on the board.

SThe control assembly should be mounted before wires are attached.

SDuring thermostat installation, provide sufficient excess wiring behind

the mounting plate. Coil the wiring, creating a service loop, and place in

mounting box or behind the wall to remove strain against the terminal

strip. See Fig. 2.
