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 sys-
tem 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.

Details of Auto Recovery Operation:
Auto Recovery can be disabled by sliding the Re-
covery switch on the circuit board to the DISABLE
position. Refer to page 13.
Auto Recovery will not operate if Permanent hold,
Temporary hold or Home Today is in operation.
Auto Recovery can be canceled manually if HOLD/
RETURN is pressed during the recovery process. If a
recovery process is canceled manually then the re-
covery 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).
When the thermostat is in Auto Recovery mode, the display will
alternate RECO with time, and the program indicator will flash.
For example, in Heat mode, you could have the follow-
ing programs:
Program #4 (Overnight) Program #1 (Morning)
Set Temp = 16 C Set Temp = 20 C
Time = 10pm Time = 6am
The room temperature fell to 16 C overnight. Rather
than having the thermostat turning on at 6am, Auto
Recovery would note the temperature difference be-
tween 16 C and 20 C and turn the Heat on approxi-
mately 30 minutes early. Therefore, the room tempera-
ture at 6am would be about 20 C instead of 16 C.

Auto Recovery will be canceled and change to
Home Today mode if HOME TODAY is pressed
during the recovery process.
Auto Recovery will be canceled and change to
Temporary Manual Override mode if the setpoint
is adjusted during the recovery process.
If the system is changed between heat and cool
then the thermostat will recalculate Auto Recov-
ery 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.
