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. 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 would result in minor personal injury or product and property damage. NOTE is used to highlight suggestions which may result in enhanced installation, reliability, or operation.

INTRODUCTION

Bryant thermostats are wall-mounted, low-voltage thermostats which maintain room temperature by controlling the operation of a heating and air conditioning system. Separate heating and cooling setpoints, plus auto changeover provide maximum comfort and flexibility. Batteries are optional; temperature and mode settings are preserved with the power off.

INSTALLATION CONSIDERATIONS

POWER

Note that all thermostats are dual powered where batteries can be installed or in the presence of R and C (24vac) are not required. 2 AA batteries are furnished with the product.

MODELS

There are 3 different models. The 9th and 10th letters of the part number indicate the model. These 2 letters also 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.

USE EACH ONLY FOR ITS INTENDED PURPOSE. SEE TABLE 1.

INSTALLATION

•Close to or in a frequently used room, preferably on an inside partitioning wall.

•On a section of wall without pipes or duct work.

Thermostat should NOT be mounted:

•Close to a window, on an outside wall, or next to a door leading to the outside.

•Exposed to direct light and heat from a lamp, sun, fireplace, or other temperature-radiating object which may cause a false reading.

•Close to or in direct airflow from supply registers and return-air grilles.

•In areas with poor air circulation, such as behind a door or in an alcove.

II. SELECT MODEL

AC Model (1-stage cool, 1-stage heat) is to be used for single- stage heating and/or cooling applications only. It CANNOT be used with optional outdoor temperature sensor. (See Table 1.)

HP Model (1-stage cool, 2-stage heat) can be used with a single-speed heat pump (HP), or an air conditioner (AC) with a 2-stage furnace or fan coil. Software Option 5 selects HP/AC operation. This thermostat comes configured from the factory as a heat pump thermostat. Select AC in software Option 5 for AC operation. When AC operation is selected, the O/W2 terminal is converted from a reversing valve output (O) to a second-stage heat output (W2). This output can be used to control 2-stage furnaces or 2-stage electric heat in fan coils. (See Table 1.)

2S Model is for 2-speed compressor systems only (HP and AC). Output Y1 controls compressor low speed and output Y/Y2 controls compressor high speed. (See Table 1.)
