About your new thermostatBuilt-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). When the safe wait time has 
elapsed, the message stops flashing and the 
compressor turns on.
Message flashes until safe restart time has elapsed.

About your new thermostat
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.
