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
re-started too soon after shutdown. This feature
forces the compressor to wait a few 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.
