■ Position wallplate on wall and pull existing wires through large opening. Then level for ap-
pearance. Mark holes for plastic anchors provided, if your existing holes do not line up with
those on the Hunter wallplate.
Wire Labeling (Continued)
■ After labeling wires, disconnect them from the existing thermostat terminals.
■ Remove existing wallplate. To make sure wires do not fall back into wall opening, you may
want to tape them to the wall.
■ Drill holes with 3/16” bit and gently tap anchors into the holes until flush with wall.
■ Reposition wallplate to wall, pulling wires through large opening. Insert mounting screws
provided into wall anchor and tighten. See Figure 3.
■ If hole in wall is larger than necessary for wires, seal this hole with insulating material so that
no hot or cold air can enter the back of the thermostat from the wall. This air could cause a
false thermostat reading.
NOTE: 5-wire Systems
If your thermostat has one wire marked R or RH (2, 3, or 4-wire system), then leave the jumper
wire between the RH and RC terminals on the wallplate. Otherwise, if you have separate RH and
RC wires (5-wire system), then remove the jumper wire between the RH and RC terminals.
If the code letter on your
existing thermostat is

■ Refer to the Wiring Diagrams below to be sure your system is wired correctly.
■ If your system is a single stage heat pump and uses an O or B wire, you must move the Sys-

furnace or electric system, leave the switch in the Standard position. Refer to the System

■ Heating System Selector (HG - HE switch)
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.

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.
To run the Fan on continuously, slide the Fan switch to the ON position.

Auto Recovery
TROUBLESHOOTING
Problem
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.
Solution
No Display
1. Check battery connections and batteries.
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.
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 indicator
will flash.
Entire Display Dims
1. Replace Batteries
■ Auto Recovery can be disabled by sliding the Recovery
switch on the circuit board.
Program Does Not Change
at your Desired Setting
1. Check that the time is set properly to “AM”
or “PM”.
2
HEAT TEMP
■ Auto Recovery will not operate if Permanent hold or Tempo-
rary hold is in operation.
2. Check that the thermostat is not in Permanent
HOLD mode.
■ 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
information.
6. If your non-heat pump system only uses 4-wires, be
sure the jumper wire is installed between the RC and
RH terminals.
Auto Cut Off
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).
7. Check the position of the System Selector switch:
Standard or Heat Pump.
Note that if your system has malfunctioned and no longer responds to thermostat controls, the
Auto Cut-Off will have no effect.
Erratic Display
1. Press the reset button once with a small pin and hold
for two seconds. Then reprogram.
If unit continues to operate
in the Off position
1. Replace unit.
1. Replace unit.
Thermostat permanently
reads “HI”, “LO”, or “ERR”
If you experience any other problems, call 1-888-830-1326 from 8 AM to 5 PM Central Time
for technical assistance.
