IMPORTANT  
air conditioning, or space heating units in use in the  
United States.  
Read the entire installation section of this  
1Owner’s Manual thoroughly before you begin  
to install or operate your Hunter Thermostat.  
This Hunter Thermostat will NOT control multi-  
stage heat pumps or 110/220 Volt systems.  
REMOVE THE MYLAR LABEL FROM THE LCD DISPLAY  
WINDOW.  
COMPRESSOR PROTECTION  
The thermostat provides a 3.5 minute delay after  
5shutting off the heating or cooling system before  
it can be restarted. This feature will prevent damage  
to your compressor caused by rapid cycling. Note  
that this delay also applies to the heating system  
control. It does not prevent a rapid compressor re-  
start due to short power outages.  
INSTALLATION  
All installation is normally performed at your  
2thermostat.  
ARMCHAIR PROGRAMMING  
You can program your thermostat before  
3installation by inserting the batteries and following  
the instructions starting on page 16. This can be done  
while you relax in your favorite chair and is a very  
good way to familiarize yourself with all the functions  
of your Hunter Thermostat.  
TEMPERATURE RANGE  
Your thermostat can be programmed between  
64°C and 35°C (45°F and 95°F). However, it will  
display room temperatures from 0°C and 37°C (32°F  
to 99°F). “HI” will be displayed if the temperature is  
higher than 37°C (99°F), and “LO” will be displayed  
if the temperature is lower than 0°C (32°F).  
OPERATION  
Your Thermostat is designed to operate with  
4most gas, oil, electric or 2-wire hot water heating  
and air conditioning systems. It will also operate  
single-stage heat pumps that do not have auxiliary  
or emergency heat. These have 24-volt or millivolt  
control systems and represent most central heating,  
This thermostat will automatically cut off in Heat  
mode if the temperature rises above 35°C (95°F),  
and automatically cut off in cool mode if the tem-  
perature drops below 7°C (45°F).

POWER FAILURE  
change the batteries and keep thermostat’s clock and  
program settings. Once the batteries have become too  
low to ensure proper operation, your system will be  
turned Off, and the display will be cleared except for  
the Low Battery indicator flashing on the LCD display.  
Whenever the main power is interrupted or fails,  
7the battery power retains the programs and cur-  
rent time.  
AUTO RECOVERY  
Your thermostat is set from the factory to gradually  
8recover the room temperature from an energy sav-  
ing program to your comfort program. Therefore, the  
thermostat may turn your system on several minutes  
prior to your programmed time. This operation is nor-  
mal, but can be turned off. Refer to the Selector  
Switches information on page 24.  
CAUTION: Once the Low Battery only display oc-  
curs, the thermostat is shut down, and your sys-  
tem will no longer operate. In this condition,  
there is no temperature control of your dwelling.  
NOTE: If you plan to be away from the premises  
over 30 days, we recommend that you replace  
the old batteries with new alkaline batteries  
prior to leaving.  
BATTERY WARNING  
Fresh alkaline batteries should provide over one  
9year of service. However, when the batteries be-  
come drained, the Low Battery indicator will flash on  
the display. When this message occurs, install 2 new  
AA batteries. You have approximately 1 minute to

What You Need  
This thermostat includes two #8 screws and two wall  
anchors for mounting. To install your thermostat, you  
should have the following tools and materials.  
Phillips and Slotted Screwdrivers  
Hammer  
Electric drill and 3/16" bit  
Two 1.5 V (AA) size alkaline batteries  
Remove Old Thermostat  
CAUTION: Do not remove any wiring from exist-  
ing thermostat before reading the instructions  
carefully. WIRES MUST BE LABELED PRIOR TO  
REMOVAL.  
TYPICAL HOME THERMOSTATS  
Figure 1  
IMPORTANT! Turn off the power to the furnace at  
the main power panel or at the furnace.  
Remove existing thermostat cover. See Figure 1.  
Some thermostats will have screws or other lock-  
ing devices that must first be removed. Once wall  
mounting plate is exposed, look for wires.

Wire Labeling  
9
Each wire coming from the wall to the existing  
thermostat is connected to a terminal point on  
that thermostat. Each of these terminal points is  
usually marked with a code letter as shown in  
Table A on the next page.  
IMPORTANT! BEFORE DISCONNECTING ANY  
WIRES, APPLY THE SELF-ADHESIVE LABELS PRO-  
VIDED TO THE WIRE AS SHOWN IN TABLE A ON  
THE NEXT PAGE. (For example, attach the label  
marked W to the wire that goes to the W or H  
terminal on your existing thermostat.) IGNORE  
THE COLOR OF THE WIRES since these do not  
always comply with the standard.  
Note that this thermostat has multiple function  
terminals that allow Single-Stage Heat Pump ca-  
pability. Standard systems use: Rh, Rc, G, W.  
[Single-Stage Heat Pumps use: Rh, Y1, G, and O or  
B.] Table A below shows the multiple functions of  
the terminals. Use the terminals that match your  
system.  
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.  
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 thermo-  
stat from the wall. This air could cause a false  
thermostat reading.  
The number of wires in your system can be as few  
as two (for heat only systems), as many as eight,  
or any number in between. If you follow the label-  
ing procedures correctly, you do not have to be  
concerned about how many wires there are.  
There is often no ter-  
minal marking on the  
G
Y
existing thermostat of  
two wire, heat only  
systems. Just connect  
either of the wires to  
the RH terminal, then  
connect the other wire  
to the W terminal to  
complete the circuit.

Mount Wallplate and Thermostat  
11  
Remove the wallplate from your thermostat by  
pressing the release tab on the bottom of the  
thermostat. (See Figure 2.)  
Position wallplate on wall and pull existing wires  
through large opening. Then level for appearance.  
Mark holes for plastic anchors provided if your  
existing holes do not line up with those on the  
Hunter wallplate.  
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.)

Your thermostat can be programmed for week-  
days and weekends, or have unique programs for  
all 7 days. Use Weekday/Weekend Programming  
below or 7-day Programming on page 21 to enter  
or revise programs to match your Personal Pro-  
gram Schedule.  
Familiarize yourself with Manual Programming, so  
that you can easily modify your programs as your  
comfort needs change. The example below dem-  
onstrates how to program your thermostat.  
NOTE: 1) The program time can be set in 10  
minute increments, and remains the  
same for both Heat and Cool programs.  
2) The program temperature can be set  
in increments of 1°C (1°F).  
3) After 15 seconds without a key press,  
the thermostat will return to normal  
display mode.  
4) When setting the program time, note  
the AM / PM indicator.  
5) With the Auto Recovery feature en-  
abled, you do not need to set your  
comfort program times early. Auto  
Recovery will determine how early to  
turn your system on, so that the room  
is comfortable at the program time.

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.  
For example, in Heat mode, you could have the follow-  
ing programs:  
Program #4 (Overnight)  
Set Temp = 16°C  
Time = 10pm  
Program #1 (Morning)  
Set Temp = 20°C  
Time = 6am  
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.  
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.  
When the thermostat is in Auto Recovery mode, the display will  
alternate RECO with time, and the program indicator will flash.

Details of Auto Recovery Operation:  
33  
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 be canceled and change to  
Home Today mode if HOME TODAY is pressed  
during the recovery process.  
Auto Recovery will not operate if Permanent hold,  
Temporary hold or Home Today is in operation.  
Auto Recovery will be canceled and change to  
Temporary Manual Override mode if the setpoint  
is adjusted during the recovery process.  
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).  
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.

SPAN Setting Mode  
Your thermostat is set at the factory to cycle at  
0.5˚C (1˚F) above and below the set temperature.  
(Span = 2) This setting has been designed to pro-  
vide 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.  
Press and hold BOTH for three seconds. The display  
will flash, and SPAN will be displayed on the LCD.  
Press to raise the Span to 3. This setting INCREASES  
the cycle time by allowing your system to run  
LONGER.  
Press to lower the Span to 1. This setting  
DECREASES the cycle time by causing your  
system to run SHORTER.  
41665-01.pmd Download from Www.Som34anuals.com. All Manuals Search9A/3n0/d03D, 5o:w40nPloMad.  
The Span settings remain the same for both HEAT  
and COOL.  
When batteries are installed in the thermostat, or  
the Reset key is pressed, the Span is reset back to  
setting 2.  
The Span can be changed at any time, and is inde-  
pendent of program times or temperatures.

SAFETY FEATURES  
36  
Error Mode  
37  
If the thermostat is unable to control your system due to an unex-  
pected 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.  
If Error Mode returns, please call Hunter Technical support at  
1-866-268-1936 for further information.  
Auto Cut Off  
Your thermostat will automatically cut-off in Heat  
mode if the room temperature rises above 35˚C (95˚F).  
It will cut-off in Cool mode if the room temperature  
drops below 4˚C (40˚F).  
NOTE: If your system has malfunctioned and no  
longer responds to thermostat controls, the Auto  
Cut-Off will have no effect.
