required
6) Selects time format display 12hours or 24hours
7) Select Compressor Lockout COMP OFF or ON.
Selecting COMP ON will cause the thermostat to wait 4 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 set point for
about four minutes.
