Minimum-Off Timer Compressor

Protection

The thermostat has an adjustable Minimum-Off Timer that
can be set from zero to five minutes (Factory Setting—five
minutes). The Minimum-Off Timer can be bypassed
through the Installer System Test or it can be bypassed
permanently by setting the Minimum-Off Timer to 0
minutes in the Installer Setup. The Minimum-Off Timer is
activated after the compressor turns off:
— If the thermostat is system powered (common wire),
the Minimum-Off Timer is also activated upon initial
startup and after power interruptions.
— If there is a call for cooling or heating during the
Minimum-Off Time, the thermostat displays “Wait.”
