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." - When the Minimum Off Timer expires, "Cool On" or "Heat On" (heat pumps only)" appears solidly in the display and the compressor and fan turn on. Indoor Temperature Sensor Allow indoor temperature sensor to absorb the air for a minimum of five minutes before taking a reading. See the Sensor instructions for more information.
