HEATING
Move the heating setpoint lever on the T874 about
10°F (6°C) above room temperature. Heating equipment
should start and the fan should run. Move the heat lever
about 10°F (6°C) below room temperature. The heating
equipment and fan should shut off.
NOTE: In heat pump applications, a minimum off-timer
provides a five-minute time delay before starting com-
pressor when the thermostat last turned the compressor
off, or when the system first received power. This delay
prevents compressor short cycling.
