EIM Notes
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 4 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 4 is set to 2° F (1.0°
C), the indoor temperature must be 2° F
(1.0° C) away from the setpoint before
stage 4 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.
No ISU 3010 Temperature Control Options
must be set to Advanced to view or adjust
this ISU.
This ISU is only displayed if ISU 2010
Heating Equipment Type is Geothermal

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
