stage heating or cooling systems, 110/220 V  
systems, or 3 wire zone systems.  
COMPRESSOR PROTECTION  
• Remove the mylar label from the display  
window.  
The thermostat provides a 4-minute delay  
5after shutting off the compressor before it  
can be restarted. This feature will prevent  
damage to your air conditioner compressor  
caused by rapid cycling. It does not provide a  
delay when there are power outages.  
INSTALLATION  
All installation is normally performed at your  
2thermostat.  
PROGRAMMING  
TEMPERATURE RANGE  
You can practice programming before  
3installing your thermostat by inserting and  
connecting the batteries and following the  
instructions on page 14. 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.  
Your thermostat can be programmed between  
640°F and 95°F (5°C and 35°C). However, it will  
display room temperatures from 32°F to 99°F (0°C  
and 37°C).  
POWER FAILURE  
Whenever the main power is interrupted or  
7fails, the battery power retains the programs  
and current time.  
OPERATION  
Your Hunter Thermostat is designed to  
4operate with most gas, oil, electric or 2-wire  
hot water heating, and air conditioning systems  
that have 24-volt or millivolt control.  
 
BATTERY WARNING  
CAUTION: The batteries are the only source  
of power used to operate your system. If you  
do not replace the batteries, the display will  
dim and your heating and cooling system will  
stop operation.  
When the batteries are low, the “LOW BATT”  
8indicator on the display will flash. When this  
happens, install new batteries immediately.  
Once the “LOW BATT” indicator appears, the  
thermostat will continue to operate for  
approximately 30 days. (Only alkaline batteries  
should be used in your thermostat.  
Rechargeable batteries have different properties  
which may cause the thermostat to not operate  
properly. Do not use old batteries.) The batteries  
should last one year.  
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.  
How This Thermostat Works…And Saves You Money  
This thermostat is designed to optimize the use of your heating and cooling equipment. It  
does this by matching your comfort (the temperatures in your home) to your schedule.  
An example:  
6:00 am You wake up. Program 1 has the heat set to 70° (21°C).  
7:30 am You leave for work. The second program turns the heat back to 62° (17°C)  
while you are away.  
5:00 pm You come home. The third program has already warmed your house back  
to 70° (21°C).  
10:00 pm You go to bed. A half hour later, program 4 turns the heat back to 64° (18°C)  
to save energy while you are under the blankets.

What You Need  
This thermostat comes with two #8 slotted screws and two wall anchors for mounting. To  
install your unit, you should have the following tools and materials.  
Slotted screwdriver  
Hammer  
Electric drill and 3/16" bit  
Two 1.5V (AA) Size Alkaline batteries  
Remove Old Thermostat  
CAUTION: Do not remove any wiring from existing thermostat before reading the  
instructions carefully. Wires must be labeled prior to removal.  
IMPORTANT! Turn off the power to the furnace at the main power panel or at the furnace.  
Remove existing thermostat cover and thermostat. See Figure 1. Some thermostats 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).

Label Wires  
10-11  
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 page 11.  
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 labeling procedures correctly, you do not  
have to be concerned about how many wires there are.  
There is often no terminal marking on the existing thermostat of two wire, heat only systems.  
Do not worry, just connect either of the wires to the RH terminal, then connect the other wire  
to the W terminal to complete the circuit.  
IMPORTANT! BEFORE DISCONNECTING ANY WIRES, APPLY THE SELF-ADHESIVE LABELS  
PROVIDED TO THE WIRE AS SHOWN IN TABLE A ON PAGE 11. (For example, attach the  
label marked W to the wire which 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.  
After labeling wires, disconnect them from the existing  
thermostat terminals.  
Y

RC  
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.

Wire Labeling  
NOTE: If your thermostat has one wire marked R or RH (4-wire system), then leave  
the jumper wire between the RH and RC terminals. Otherwise, if you have separate  
RH and RC wires (5-wire system), then remove the jumper wire between the RH and  
RC terminals.  
NOTE: Do not connect a Common” wire (sometimes labelled C) to any terminal on  
this thermostat. Tape up the wire and do not use. This wire provides electricity to non-  
battery powered thermostats.  
 
Mount Wallplate and Thermostat  
Snap open the wallplate from your thermostat by pressing the release tab on the bottom of  
the thermostat.  
Position wallplate on wall and pull existing wires through large opening. Then level for  
appearance. Mark holes for plastic anchors provided if existing holes do not line up with  
Hunter Thermostat holes.  
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 2.)

Selector Switches  
The heating system selector and the F°/C° selector switches are located on the Printed  
Circuit Board.  
Heating system selector  
The heating system selector is a switch on the Printed Circuit Board on the inside of the  
thermostat. The switch is at “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. Leave the switch in the “HG” position. If the fan does not come on when the  
thermostat calls 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.  
/C° selector (Fahrenheit/Centigrade)  
Your thermostat is set for F° mode from the factory. In order to  
HE  
HG  
change to C° mode, slide the switch to C° and press reset  
button on front of the thermostat with a paper clip. The reset  
button is located near the display.  
C
F
NOTE: Unless reset button is pressed, the thermostat will  
not change the mode.  
Connect Wires and Mount Thermostat Cover to Wall Plate  
Match and connect the labeled wires to the appropriate coded terminal screws on the  
mounting plate. (See Figure 3, 4.) Ignore any wires which may be present, but which were  
not connected to the old thermostat.  
 
Be sure to tighten the terminal screws securely, otherwise a loose wire could cause operational  
problems with your system or thermostat.  
Push excess wire back into hole to prevent interference with mounting of the thermostat cover.  
Make sure the Function Switch is set at OFF, and the FAN-AUTO Switch is in AUTO.  
Insert the bottom tab on the thermostat body into the slot at the bottom of the wallplate.  
Press top of the thermostat body to snap it into the wallplate. (NOTE: Do not force the  
thermostat onto the wallplate, as the terminal pins may be damaged. If it does not  
snap properly, the thermostat may not work.)  
Insert the two AA size batteries, observing the  
polarity marked on the unit.  
Switch on the main power. Press the reset button.  
(See Figure 5.)  
The LCD display indicates the current room  
temperature of your house. If it shows random  
numbers or partial digits, press the reset button  
once again.  
The installation is now complete. Continue reading
