Built-in Compressor Protection
The RTH7400D 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.
