5) Select Compressor Lockout LOC OFF or ON - Selecting
LOC 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 cycles. This is intended to help protect the compres-
sor 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 feature is
already present in their system. When the compressor time
delay occurs it will flash the (snowflake icon) for about five
minutes then turn on the compressor.
6) Select Temperature Display Adjustment 4 LO to 4 HI -

temperature to match your previous thermostat.
7) Select F° or C° Readout - Changes the display readout to
Centigrade or Fahrenheit as required.
