Minimum-Off Timer Compressor

Protection

The TH5110 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 flashes “Cool On” or
“Heat On”

. When the Minimum Off Timer expires, “Cool

On” or “Heat On”

appears solid in the display and the

compressor and fan turn on.
