IMPORTANT  
SYSTEM COMPATIBILITY  
Read the entire installation section of this Owner’s Manual  
thoroughly before you begin to install or operate your  
Hunter Thermostat.  
Your Thermostat is designed to operate these  
24-Volt systems:  
1
4
Multi-stage heat pumps with auxiliary heat  
Single-stage heat pumps  
2, 3, or 4 wire gas, oil, and electric furnaces and air condition-  
ing systems  
Remove the Mylar label from the LCD display window.  
INSTALLATION  
All installation is normally performed at your  
2
thermostat.  
This thermostat will not control 120/240 Volt systems or  
millivolt systems.  
ARMCHAIR PROGRAMMING  
You can program your thermostat before installation by in-  
COMPRESSOR PROTECTION  
3
serting the batteries and following the instructions starting  
The thermostat provides a 3.5 minute delay after shutting off  
5the heating or cooling system before it can be restarted.  
This feature will prevent damage to your compressor caused  
by rapid cycling.  
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.  
7
TEMPERATURE RANGE  
BATTERY WARNING  
Your thermostat can be programmed between 45°F and 95°F  
(7°C and 35°C). However, it will display room temperatures  
from 15°F to 99°F (-9°C and 37°C). “HI” will be displayed if the  
temperature is higher than 99°F (37°C), and “LO” will be dis-  
played if the temperature is lower than 15°F (-9°C).  
Fresh alkaline batteries will provide over one year of memory  
9backup and clock operation. However, when the batteries  
become drained, a low battery warning will appear on the dis-  
play. When this message occurs, install 2 new AAA batteries. You  
have approximately 30 seconds when changing the batteries to  
keep thermostat’s clock and program settings.  
6
AUTO RECOVERY  
Your thermostat is set from the factory to gradually recover  
NOTE: The default system selection at power-on is HEAT.  
Batteries are recommended to prevent an undesired sys-  
tem change due to a power outage.  
7
the room temperature from an energy saving program to  
your comfort program. Therefore, the thermostat may turn your  
system on several minutes prior to your programmed time. This  
operation is normal, but can be turned off. Refer to the Options  
Menu information on pages 16.  
OPERATION  
This system operates on your system’s 24 Volt power supply.  
8
The supply is monitored by the thermostat, and it will stop  
functioning if AC power is lost. (When using backup batteries,  
No AC Pwr” will be displayed.) All system controls will remain  
off until power is restored.  
®
NOTE: The INDIGLO Night-Light will not function when  
AC power is lost.

What You Need  
This thermostat includes two #8 slotted screws and two wall an-  
chors for mounting. To install your thermostat, you should have  
the following tools and materials.  
Slotted Screwdriver(s)  
Phillips Screwdriver  
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 existing ther-  
mostat 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 ther-  
mostats will have screws or other locking devices that must  
first be removed. Once wall mounting plate is exposed, look  
for wires.

If wires are not visible, they may be connected to the back of  
the wallplate. Again, look for screws, tabs, etc. Some models  
have doors that open to expose wires and mounting screws.

See Figure 1).  
Wall Mounting Plate

Wire Labeling  
11  
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.  
SHOWN IN TABLE A and B ON PAGES 12-13. (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.  
The number of wires in your system can be as few as four  
After labeling wires, disconnect them from the existing ther-  
mostat 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  
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.  
(
for single-stage systems), as many as eight, or any number  
in between. If you follow the labeling procedures correctly,  
you do not have to be concerned about how many wires  
there are.  
IMPORTANT! BEFORE DISCONNECTING ANY WIRES, APPLY  
THE SELF-ADHESIVE LABELS PROVIDED TO THE WIRE AS

Programming Introduction  
Studies conducted by the Department of Energy estimate that  
setting your thermostat back 10°F (6°C) for two 8-hour periods  
during winter can reduce your fuel bill by as much as 33%. By  
setting your thermostat up 5°F (3°C) for two 8-hour periods dur-  
ing summer you can reduce your fuel bill up to 25%.  
You can program weekdays as a group, weekends as a group, all  
7 days individually or everyday as a group.  
The system fan may also be set to run continuously during a pro-  
gram time period.  
Your Hunter thermostat is pre-programmed to meet the ENERGY  
Your thermostat is capable of holding up to 4 separate programs  
for each day of the week.

) If the system selector is in AUTO mode, the  
current operating mode will be used for pro-  
gramming.  
Familiarize yourself with Manual Programming, so that you  
can easily modify your programs as your comfort needs  
change. Follow the steps below to change the program times  
and temperatures.  
5) After 15 seconds without a key press, the ther-  
mostat will return to normal display mode.  
6) When setting the program time, note the AM /  
PM indicator.  
NOTE: 1) The program time can be set in 10 minute incre-  
ments, and remains the same for both Heat and  
Cool programs.  
7) With the Auto Recovery feature enabled, 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 com-  
fortable at the program time.

Auto Season Changeover

When the System Selection is in AUTO position, the thermostat  
will automatically change between Heating and Cooling systems,  
depending on your program. We recommend keeping your pro-  
grammed heating and cooling temperatures at least 5°F (3°C)  
apart to allow the Auto Season Changeover to occur when the  
appropriate temperature span has been reached. However, if  
your heating and cooling programs set temperatures are close,  
there is a built-in program to prevent the thermostat from  
changing unnecessarily.  
play. “AUTO” will return when these holds are cleared. Auto Sea-  
son Changeover will still function in Home Today mode, as this is  
a comfort setting.  
For example, you may have the following temperatures pro-  
grammed at a given time:  
Heat Set Temp = 68°F  
Cool Set Temp = 78°F  
If the room temperature rises above 78°F, then the thermostat  
will automatically change to cool mode and turn on the air  
conditioner.  
Auto Season Changeover is disabled when the thermostat is in  
Temporary or Permanent Override, or Vacation Hold, as these  
overrides are energy saving settings. While in any of these  
modes, “AUTO” will be temporarily removed form the LCD dis-  
Likewise, the thermostat will automatically change to heat mode  
and turn on heat when the room temperature falls below 68°F.

SPAN Settings  
STAGE 1  
The Span settings remain the same for both HEAT and COOL.  
Your thermostat is set at the factory to cycle at 1°F (0.5°C)  
above and below the set temperature in Stage 1. (Span = 2.) This  
setting has been designed to provide a comfortable room tem-  
perature under most all conditions. However, if you find your sys-  
tem cycling too fast or too slow, then the Span can be adjusted  
to modify the cycle time. Refer to the Option Menu Stage 1 Span  
selection on page 17.  
The Span can be changed at any time and is independent of pro-  
gram times or temperatures.  
When the thermostat is powered on or the Reset key is pressed,  
the Span is reset back to setting 2.  
Span = 1. This decreases the cycle time by causing your  
system to run shorter.  
Span = 3. This increases the cycle time by causing your  
system to run longer.

System  
Fan  
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.  
Details of Auto Recovery Operation:  
Auto Recovery can be disabled by selecting “NO” in the Op-  
tion Menu. Refer to page 17.  
For example, in Heat mode, you could have the following  
programs:  
Auto Recovery will not operate if Permanent hold, Vacation  
hold Temporary hold or Home Today is in operation. It will  
also not operate if the thermostat resets due to AC power loss  
with no backup batteries.  
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.  
Auto Recovery can be canceled manually if RET 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).

Auto Recovery (continued)  
Auto Recovery will be canceled if HOME TODAY or HOLD is  
pressed during the recovery process. The thermostat will enter  
Home Today, Permanent hold or Vacation hold.  
If the system changes between heat and cool (automatically  
or manually) then the thermostat will recalculate Auto Recov-  
ery again. Setpoint temperature will be changed to the oppo-  
site 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.  
Auto Recovery will be canceled and change to Temporary  
Manual Override mode if the setpoint is adjusted during the
