The Legacy Line- -RNC Series thermostat is an electronic 24VAC,
non- -programmable, manual changeover wall mount thermostat.
This thermostat uses a single setpoint to maintain and control room
temperature in both the heating and air conditioning modes. The
thermostat is designed to maintain +/- - 2_F accuracy. No batteries
are required; temperature, fan, mode, and installer configuration
settings are preserved with power off.
INSTALLATION CONSIDERATIONS
Air Conditioner Model
T1- -NAC, Legacy Line- -RNC Series Model air conditioner
thermostat, may be wired with or without connecting a common
wire between the indoor equipment and the thermostat. However, it

This means it will need to steal a small amount of power from the
equipment to which it is connected.

stealing type thermostats. All Bryant equipment is directly
compatible with this thermostat except the Thermostat Conversion
