Built-in Compressor Protection
The RTH8500D 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 shows
“Wait” 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.
