72. 7 I. OPERATION Auto Recovery Hunter's Auto Recovery feature meets the ENERGY STAR® guidelines for energy efficiency by allowing the heating or cooling system to recover gradually from an energy-saving setpoint temperature to a comfort setpoint temperature. Auto Recovery calculates how early to turn your system back On, so that the room temperature is already comfortable by the start of the comfort temperature program period. Auto Recovery works in both Heat and Cool modes. For example, in Heat mode, you could have the following programs: Program #4 (Overnight) Set Temp = 60°F Time = 10pm Program #1 (Morning) Set Temp = 68°F Time = 6am The room temperature fell to 60°F overnight. Rather than having the thermostat turning on at 6am, Auto Recovery would note the temperature difference between 60°F and 68°F and turn the Heat on approximately 30 minutes early. Therefore, the room temperature at 6am would be about 68°F instead of 60°F. s When the thermostat is in Auto Recovery mode, the display will alternate "RECV" with time, and the program indicator will flash.

Refer to page 15. s Auto Recovery will not operate if Permanent hold, Temporary hold or Home Today is in operation. s Auto Recovery can be canceled manually if HOLD/CLEAR is pressed during the recovery process. If a recovery process is canceled manually then the recovery process will not start again until the next program period starts (an exception is that if time or program is changed then the thermostat will check Auto Recovery conditions immediately). s Auto Recovery will be canceled and change to Home Today mode if HOME TODAY is pressed during the recovery process. s Auto Recovery will be canceled and change to Temporary Manual Override mode if the setpoint is adjusted during the recovery process. s If the system changes between heat and cool (automatically or manually) then the thermostat will recalculate Auto Recovery again. Setpoint temperature will be changed to the opposite system's comfort temperature if the recovery entry criteria are still met. Otherwise, the recovery process will be canceled and return to program control mode.
