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 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, 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

Carrier's 7-day programmable/non-programmable Thermidistat Control is a wall-mounted, low-voltage control which combines temperature and humidity control in a single attractive unit. An extension of Carrier's proven line of thermostats, it provides separate set points for heating and cooling, and now adds humidi- fication and dehumidification. Different heating and cooling set points and times are programmable for 4 periods per day and 7 days per week. The Thermidistat Control can also be field- configured as a non-programmable thermostat. When operating in the non-programmable configuration it will still have both tem- perature and humidity control. Humidify and dehumidify outputs provide direct control of humidity. Batteries are not used. During power loss an internal memory stores programs and settings for unlimited time, and the clock continues to run for at least 8 hr.

INSTALLATION CONSIDERATIONS

POWER

Note that this control does not require batteries and is not "power stealing." It does require 24vac (R and C terminals) of the low-voltage transformer to be connected to it for proper operation. It will not operate without these 2 connections.

MODELS

There is a single programmable/non-programmable model for all applications. It can be configured for AC or HP, 1- or 2-speed compressor, and for dual fuel installations, allowing it to be used in place of all Carrier thermostats.

HUMIDIFY EQUIPMENT AND CONNECTIONS

The humidify output connects directly to 24vac operated humidi- fiers. No other connection or interlock is required. Any of several installer-selectable operating modes are available.

DO NOT connect Furnace HUM terminal directly to Thermidistat HUM terminal. This will bypass furnace safety controls. See Low Voltage Wiring Daigrams and notes for proper connection.

DEHUMIDIFY EQUIPMENT AND CONNECTIONS

The dehumidify 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.

OUTDOOR TEMPERATURE SENSOR

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 Thermidistat Control 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.

Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.
