2. 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
and heating cycles. This is intended to help protect the
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.
3. Select Temperature Display Adjustment 3 LO to 3 HI –
Allows you to adjust the room temperature display up to 3°
higher or lower. Your thermostat was accurately calibrated at
the factory but you have the option to change the display
temperature to match your previous thermostat. The current
