one touch of the Auto Schedule key this feature allows
you to program a desired comfort temperature into all the
program periods along with a 6° set back for night peri-

stage will not energize until the setpoint temperature is
1°F or more above actual temperature for more than ten
minutes. The Fast Cool feature (FA Cool) provides the
same controls when the setpoint temperature is lowered.
21) Comfort Alert with Active Protection – Turn this
feature ON to enable active protection. This allows the
thermostat to identify fault codes sent by the Comfort
Alert module when compressor damage is possible and
react to those codes by turning the compressor off. Fault
codes from the Comfort Alert module will flash on the
thermostat. (Refer to Comfort Alert Yellow Alert Codes
in Troubleshooting section.) If a Comfort Alert module is
not connected, or to disable active protection, turn this

changeover relay to be energized in COOL. If the
thermostat you are replacing or the heat pump being
installed with this thermostat requires a “B” terminal, to
energize the changeover relay in HEAT, the O/B option
should be set at “B” position.
