-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.
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.
Page 5
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.

WARNING 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. Dehumidify Equipment and Connections The dry contact output connects to the dehumidify input on variable- -speed furnaces and fan coils.
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.

1. Normal Dehumidify Operation When normal dehumidify is selected, the compressor will not turn on without a cooling demand. If dehumidify demand exists while cooling, dry contact will also be active (24VAC removed). This output commands variable- -speed blowers to reduce their airflow, which improves water re- moval from the cooled air.
