Page: 18 / 22

The SC2010 is a single-stage heat, single-stage cool thermostat. It functions with air conditioning, heat
pumps, gas, oil or electric heat.
The SC2010 can use 24 VAC or batteries as a power supply. The SC2010 can be hardwired and have no
batteries installed in the battery compartment. It can also run on battery power only. When batteries are
installed and the thermostat is hardwired, the batteries will run the thermostat during a power outage.
When operating on battery power, the backlight will be on for 5 second intervals. When hardwired, the
backlight will be on for 10 second intervals.
The thermostat activates a heating appliance when the room temperature is below the heat set
temperature (by the differential temperature). It will turn off when the room temperature is one degree
above the heat set temperature. With heat pumps, 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. It will turn off when the room temperature is one degree below the cool set
temperature. The thermostat will not let the compressor come on for five minutes after it turns off. This
protects your compressor.
The SC2010 has the following operating modes:
OFF , 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. 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.
