INSTALLER/CONFIGURATION MENU
20) 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 fl ash 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 fl ash the fault codes from the Comfort Alert module,
but the active protection will not be enabled to protect the
compressor.
21) Select Daylight Saving Time Calculation – Not avail-
able on 1F83, this feature will allow the thermostat to
calculate the DST automatically and apply it to the Real

period from 25 to 1975 hours in 25 hours increments.
In a typical system, 200 hours (default) of run time is
approximately 30 days. After the selected time of blower
operation, the thermostat will display “Change Filter”
as a reminder to change or clean your air fi lter. When
“Change Filter” is displayed, press MENU or RUN
SCHED button to clear the display and restart the time to

energize the changeover relay in HEAT, the O/B option
should be set at “B” position.
