Cooling System
This thermostat has a built-in short-term (5-minute) time delay.
This feature is activated after the compressor shuts down and
the setpoint is changed within the 5-minute period. During this
5-minute period, COOL will flash on the display indicating that
the thermostat has locked out the compressor to allow head
pressure to stabilize. This thermostat does not sense AC power
loss and therefore does not activate the short term compressor
protection feature when power is restored.
To prevent compressor and/or property damage, if the
outdoor temperature is below 50°F, DO NOT operate
the cooling system.

cover, gently pull it straight out from the base. To replace the
cover, line up the cover with the base and press gently until the
cover snaps onto the base.
