This ISU is only displayed for conventional
systems that have 3 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 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 will use the stage of heating as
needed to keep the indoor temperature
within 1° F (0.5° C) degree of the setpoint.
