Built-in Compressor Protection
The RTH5100B Thermostat has built-in compressor
protection (minimum-off timer) that prevents the
compressor from restarting too early after a shutdown.
The minimum-off timer is activated after the compressor
turns off.
If there is a call during the minimum-off timer, the
thermostat flashes “Cool On” or “Heat On”
a
in the display.
When the minimum-off timer expires, “Cool On” or “Heat
On”
a
appears solidly in the display and the compressor
and fan turn on.
