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 installa- tion may damage thermostat.

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, and CAU- TION. These words are used with the safety-alert symbol. DAN- GER 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 would result in minor personal injury or product and property damage.

INTRODUCTION

Bryant's 7-day programmable thermostats are wall-mounted, low- voltage thermostats which maintain room temperature by control- ling the operation of a heating and air conditioning system. Separate heating and cooling setpoints, plus auto changeover allow setback programming for maximum energy savings. All of the thermostats allow up to 4 time/temperature settings to be pro- grammed per 24 hr period and store programs for 7 independent days. Batteries are not required; during a power interruption, the internal memory stores programs for an unlimited time and the clock continues to run for at least 72 hrs.

INSTALLATION CONSIDERATIONS

POWER

Note that all TSTAT models require no batteries and are not "power stealing". They do require 24VAC (R and C terminals) to be connected for proper operation. Thermostat will not operate without these 2 connections.

MODELS

There are 3 different models. The 9th and 10th letters of the part number indicate the model. These 2 letters appear on the package and on the circuit board. Be sure to have the proper thermostat for the intended application. Models are:

AC - 1-stage cool, 1-stage heat - for AC systems only.

HP - 1-stage cool, 2-stage heat - for either HP or AC with 2-stage heat.

2S - 2-stage cool, 2-stage heat - for 2-speed AC systems, or 2-stage cool, 3-stage heat - for 2-speed HP systems, or

1-stage cool, 4-stage heat - for 1-speed HP with special 3-stage electric heat.

Use each only for its intended purpose. (See Table 1.)

OUTDOOR TEMPERATURE SENSING

All Bryant programmable thermostats may be equipped with an

optional outdoor temperature sensor, Part No. TSTATXXSEN01-B. If it is to be used, plan installation so that 2 wires can be run from the thermostat 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 used for its connection. Details are provided to the sensor instructions.

INSTALLATION

I.THERMOSTAT LOCATION

Thermostat should be mounted:

·Approximately 5 ft (1.5m) from floor.
