INTRODUCTION Bryant’s 7--day, 5/2--day, 1--day programmable and non--programmable Preferredt Series Thermidistatt 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.
Rh terminal. Connect R from the outdoor unit to the Rc terminal. Then, break jumper on the circuit board. The W and G signals are taken from the Rh power and the Y and O signals are taken from the Rc power. If thermostat 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.
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. ! 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.
