Temperature Recovery The thermostat is equipped with a feature to eliminate guesswork when setting a schedule. That is, the user need not know the amount of time for the HVAC system to bring the space to temperature (without overshoot) prior to the scheduled time.The thermostat manages that automatically. Simply set the program schedule to the desired time to have the space at comfort temperature. In addition, program the temperature to this comfort temperature. The thermostat activates the heating or cooling at the proper time to reach the scheduled temperature at the scheduled time. NOTE: The setpoint changes gradually to use economical stages and avoid overshoot. 63-2625—04 20 For example—the space will be occupied at 8:00 AM and the desired temperature is 70°F. Set the OCC 1 period for 8:00 AM and 70°F. The thermostat turns on the heat prior to 8:00 AM to raise the temperature to 70°F by 8:00 AM. The thermostat provides an alert that the heating or cooling system is coming on before a scheduled time by displaying “Recovery” on the screen. Minimum-Off Timer Compressor Protection The thermostat 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 MinimumOff 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.
