(Testing the thermostat continued from Page 22)
The SC2311 is a two-stage heat, one-stage cool thermostat. It functions with air conditioning, heat pumps,
gas, oil or electric heat.
The thermostat activates the first stage heat when the room temperature is below the heat set
temperature (by the differential temperature). Second stage heat will be activated if the room temperature
continues to drop. The heat outputs are staged off as the room temperature increases. For heat pump
systems, the thermostat will not let the compressor come on for five minutes after it turns off. This protects
your compressor.
When the room temperature is greater than the cool set temperature (by the differential temperature), the
cooling device is activated. The cool output is turned off as the room temperature drops. The thermostat will
not let the compressor come on for five minutes after it turns off. This protects your compressor.
The SC2311 has the following operating modes:
OFF
,
Heat, Emergency Heat,
and
Cool
. In
OFF
mode,
the thermostat will not turn on heating or cooling devices. In the
Heat
mode, the thermostat controls the
heating system. For heat pump systems,
Emergency Heat
mode is used to bypass the compressor (only
backup heat operates). In the
Cool
mode, the thermostat controls the cooling system. The indoor fan can be
turned on in all operating modes using the
Fan
switch.
