(Testing the thermostat continued from Page 23)
The SC2210 is a multi-stage, heat pump thermostat.
The SC2210 can use 24 VAC or batteries as a power supply. The SC2210 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 the heat pump when the room temperature is below the heat set temperature
(by the differential temperature). Auxiliary heat will be activated if the room temperature continues to
drop. Third stage heat is activated (on some systems) if the temperature drops further. The heat outputs
are staged off (configurable, setting 5, Page 20) as the room temperature increases. 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. Second-stage cooling will be activated if the room temperature continues
to rise. The cool outputs are staged off (configurable, setting 5, Page 20) as the room temperature
decreases. The thermostat will not let the compressor come on for five minutes after it turns off. This
protects your compressor.
The SC2210 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
heat pump system. In the
Emergency Heat
mode, the heat pump is bypassed and auxiliary becomes the
primary heat source. 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.
The SC2210 has an air filter check option also. When the fan run time exceeds the time set in the config-
uration (step 10, page 21), the filter reminder will be displayed. To reset the filter counter to zero and
clear the filter reminder from the display, press the and buttons in simultaneously for 5 seconds.
