1.0°F - 4.0°F from setpoint (in
0.5° F increments)
Comfort Commercial No ISU 3010 Temperature Control Options must be set
to Advanced to view or adjust this ISU.
This ISU is only displayed when the thermostat is
set to 3 cool stages.
The indoor temperature must rise to the selected
differential setting before the thermostat turns on
the stage of cooling. For example, if stage 3 is set to
2° F (1.0° C), the indoor temperature must be 2° F
(1.0° C) away from the setpoint before stage 3 turns
on. When set to Comfort, the thermostat uses the
stage of cooling as needed to keep the indoor
temperature within 1° F (0.5° C) degree of the
setpoint.

This ISU is only displayed if ISU 2010 Heating
Equipment Type is Geothermal Radiant Heat and
there are 2 radiant heat stages.
The indoor temperature must drop to the selected
differential setting before the thermostat will turn on
the stage of heating. For example, if stage 2 is set to
2° F (1.0° C), the indoor temperature must be 2° F
(1.0° C) away from the setpoint before stage 2 turns
on. When set to Comfort, the thermostat will use the
stage of heating as needed to keep the indoor
temperature within 1° F (0.5° C) degree of the
setpoint.
