Selector Switches
In order for this thermostat to control your system, the system type must be specified by the
selector switches on the printed circuit board inside the thermostat.
■ Heating System Selector (HG - HE switch)
■ Press to change the Minute up or down to
the current minute.
The factory position for this switch is in the “HG” position. Leave it in this position if you have
a gas furnace or an oil burner. If you have an electric furnace, test to see whether the Heat
and Fan come on as expected after installation. If the Fan operation is normal, leave it in the
“HG” position. If the Fan does not come on within a minute of the thermostat calling for heat,
change the switch position to “HE”. The system selector has no effect in the cooling mode.
NOTE: “HG” position is for gas and most other systems. “HE” position is for certain electric
systems having a fan relay.

Filter Change Indicator
The System Selector switch on the front of the thermostat
determines the operating mode of the thermostat. You may
select COOL, OFF, HEAT.
Your thermostat measures the number of hours your heating and cooling system has been in
use. To maximize your system’s performance and energy efficiency, change or clean your filter
regularly.

electric heat, air conditioning, and heat pump operation, the
Fan will turn on with the system.

SPAN Setting Mode
Your thermostat is set at the factory to cycle at 1˚F (0.5˚C) above and below the set tempera-
ture. (Span = 2) This setting has been designed to provide a comfortable room temperature
under most all conditions. However, if you find your system cycling too fast or too slow, then
the Span can be adjusted to modify the cycle time.

Auto Recovery
TROUBLESHOOTING
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.
Problem
Solution
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.
No Display
1. Check battery connections and batteries.
2. Press RESET button with a small pin and hold in for
two seconds.
■ When the thermostat is in Auto Recovery mode, the display
will alternate “RECO” with time, and the program indica-
tor will flash.
Entire Display Dims
1. Replace Batteries
■ Auto Recovery can be disabled by sliding the Recovery
switch on the circuit board to disable.

porary hold is in operation.
■ Auto Recovery can be canceled manually if
HOLD / RETURN is pressed during the recovery
process.
3. Check for the correct day setting.
■ Auto Recovery will be canceled and change to Temporary
Manual Override mode if the setpoint is adjusted during
the recovery process.
Auto Fan Does Not Turn
On Properly
1. Move HG/HE selector to correct position.
Heating or Cooling Does
Not Go On or Off
1. Check that the function switch is in the correct
position (“HEAT” or “COOL”).
Error Mode
If the thermostat is unable to control your system due to
an unexpected battery problem, the thermostat will enter
Error Mode. In this condition, the thermostat flashes
“Err” on the LCD display, and shuts off your system. To
correct this problem, replace the batteries with 2 new AA
alkaline batteries, even if you have recently replaced
them. Next, use a paper clip to press the RESET button
next to the keypad. You will need to reprogram your
thermostat and confirm normal operation.
2. There may be as much as 4-minute delay before the
system turns On - wait and check. (Compressor
protection delay.)
3. Check your circuit breakers and switches to ensure
there is power to the system.
4. Replace batteries.
5. Make sure your furnace blower door is closed
properly.
If Error Mode returns, please call Hunter Technical support at 1-888-830-1326 for further infor-
mation.
6. If your system only uses 4-wires, be sure the jumper
wire is installed between the RC and RH terminals.
Auto Cut Off
Erratic Display
1. Press the reset button once with a small pin and
hold for two seconds. Then reprogram.
Your thermostat will automatically cut-off in Heat mode if the room temperature rises above 95˚F
(35˚C). It will cut-off in Cool mode if the room temperature drops below 40˚F (4˚C).
Note that if your system has malfunctioned and no longer responds to thermostat controls, the
Auto Cut-Off will have no effect.
If unit continues to operate
in the Off position
