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 setpoint for about four minutes.
