In the run mode, if the setpoint temperature is manually
raised by 3°F (2°C) or more above the actual temperature
with the TEMPERATURE UP key, and the fast second stage
feature is enabled, FA on, 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.

Select Compressor Lockout CL OFF or ON – Selecting CL
ON will cause the thermostat to wait 5 minutes before turning
on the compressor if the heating and cooling system loses
power. It will also wait 5 minutes minimum between cooling

compressor from short cycling. Some newer compressors
already have a time delay built in and do not require this
feature. Your compressor manufacturer can tell you if the
lockout feature is already present in their system. When the
thermostat compressor time delay occurs it will flash the
Snowflake and Flame Icons for about five minutes.
