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-

ods of both Heat and Cool programs. Factory default is

pump or Multi-stage only, in the run mode, with the fast 

Heat feature enabled (FA Heat On), if the Heat setpoint 

temperature is manually raised by 3°F (2°C) or more 

above the actual temperature using 

 the second 

stage will energize immediately. With FA OFF, second 

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 

feature OFF. If a Comfort Alert module is connected and 

this feature is turned OFF, the thermostat will still receive 

and flash the fault codes from the Comfort Alert module, 

but the active protection will not be enabled to protect the 

compressor.

SCHED button to clear the display and restart the time to 

the next filter change.

majority of heat pump applications, which require the

 

changeover relay to be energized in 

COOL
