Built-in compressor protection
This feature helps prevent damage to the com-
pressor in your air conditioning or heat pump
system.
Damage can occur if the compressor is restarted
too soon after shutdown. This feature forces the
compressor to wait 5 minutes before restarting.
During the wait time, the display will flash the
message Cool On (or Heat On if you have a
heat pump model). When the safe wait time has
elapsed, the message stops flashing and the
compressor turns on.
Message flashes until safe restart
time has elapsed.

Early Start: This feature allows the heating or
cooling to turn on before the program start
time, so the temperature is reached at the time
you set. For example: Set the Wake time to 6
am, and the temperature to 70°. The heat will
come on before 6 am, so the temperature is
70° by the time you wake at 6. The next time
period is displayed when the system is acti-
vated before a scheduled time period.
