Read This Before Installing Thermostat
IMPORTANT
1
Read the entire installation section of this
Owner’s Manual thoroughly before you begin
to install or operate your Hunter Ther ostat.
• Re ove the ylar label fro the display
window.
INSTALLATION
2
All installation is nor ally perfor ed at your
ther ostat.
PROGRAMMING
3
You can practice progra ing before
installing your ther ostat 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 fa iliarize yourself with all the
functions of your Hunter Ther ostat.
OPERATION
4
Your Hunter Ther ostat is designed to
operate with ost gas, oil, electric or 2-wire
hot water heating, and air conditioning syste s
that have 24-volt or illivolt control.
This Hunter Ther ostat will not control ulti-
stage heating or cooling syste s, 110/220 V
syste s, or 3 wire zone syste s.
COMPRESSOR PROTECTION
5
The ther ostat provides a 4- inute delay
after shutting off the co pressor before it
can be restarted. This feature will prevent
da age to your air conditioner co pressor
caused by rapid cycling. It does not provide a
delay when there are power outages.
511/41251/book p. 1-15 2/8/01 2:24 PM Page 4

TEMPERAT RE RANGE
6
Your ther ostat can be progra ed between
40°F and 95°F (5°C and 35°C). However, it will
display roo te peratures fro 32°F to 99°F (0°C
to 37°C).
POWER FAIL RE
7
Whenever the ain power is interrupted or
fails, the battery power retains the progra s
and current ti e.
BATTERY WARNING
8
When the batteries are low the “LOW BATT”
indicator on the display will flash. When this
happens, install new batteries i ediately.
Once the “LOW BATT” indicator appears, the
ther ostat will continue to operate for
approxi ately 30 days. (Only alkaline batteries
should be used in your ther ostat.
Rechargeable batteries have different properties
which ay cause the ther ostat to not operate
properly. Do not use old batteries.) The batteries
should last one year.
CA TION: 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.
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.

Installation
This ther ostat co es with two #8 slotted screws and two wall anchors for ounting. To
install your unit, you should have the following tools and aterials.
■Slotted screwdriver ■Electric drill and 3/16" bit
■Ha er ■Two 1.5V (AA) Size Alkaline batteries
CA TION: 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 ain power panel or at the furnace.
■Re ove existing ther ostat cover and ther ostat. See Figure 1. So e ther ostats will have
screws or other locking devices that ust first be re oved. Once wall ounting plate is
exposed, look for wires.
■If wires are not visible, they ay be connected to the back of the wallplate. Again, look for
screws, tabs, etc. So e odels have doors that open to expose wires and ounting screws.
(See Figure 1).

Installation
■Each wire co ing fro the wall to the existing ther ostat is connected to a ter inal point on
that ther ostat. Each of these ter inal points is usually arked with a code letter as shown in
Table A on page 9.
■The nu ber of wires in your syste can be as few as two (for heat only syste s), as any as
eight, or any nu ber in between. If you follow the labeling procedures correctly, you do not
have to be concerned about how any wires there are.
■There is often no ter inal arking on the existing ther ostat of two wire, heat only syste s.
Do not worry, just connect either of the wires to the RH ter inal, then connect the other wire
to the W ter inal to co plete 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 exa ple, attach the
label arked W to the wire which goes to the W or H ter inal on your existing ther ostat.)
IGNORE THE COLOR OF THE WIRES since these do not always co ply with the standard.
■After labeling wires, disconnect the fro the existing
ther ostat ter inals.
■Re ove existing wallplate. To ake sure wires do not fall back
into wall opening, you ay want to tape the 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 ther ostat
fro the wall. This air could cause a false ther ostat reading.

Installation
NOTE: If your ther ostat has one wire arked R or RH (4-wire syste ), then leave the
ju per wire between the RH and RC ter inals. Otherwise, if you have separate RH and RC
wires (5-wire syste ), then re ove the ju per wire between the RH and RC ter inals.
NOTE: Do not connect a “Co on” wire (so eti es labelled “C”) to any ter inal on this
ther ostat. Tape up the wire and do not use.

Snap open the wallplate fro your ther ostat by pressing the release tab on the botto of
the ther ostat.
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 Ther ostat 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 ounting screws
provided into wall anchor and tighten. (See Figure 2.)

Selector Switches
The heating syste selector and the F°/C° selector switches are located on the Printed
Circuit Board.
■Heating system selector
The heating syste selector is a switch on the Printed Circuit Board on the inside of the
ther ostat. 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 co e on as
expected. Leave the switch in the “HG” position. If the fan does not co e on when the
ther ostat calls for heat, change the switch position to “HE.”
The syste selector has no effect in the cooling ode.
NOTE: “HG” position is for gas and most other systems. “HE” position is for certain
electric systems having a fan relay.
■F°/C° selector (Fahrenheit/Centigrade)
Your ther ostat is set for F° ode fro the factory. In order to
change to C° ode, slide the switch to C° and press reset
button on the front of the ther ostat with a paper clip. The reset
button is located near the display.
NOTE: nless reset button is pressed, the thermostat will
not change the mode.
■Match and connect the labeled wires to the appropriate coded ter inal screws on the
ounting plate. (See Figure 3, 4.) Ignore any wires which ay be present, but which were
not connected to the old ther ostat.

■Be sure to tighten the ter inal screws securely, otherwise a loose wire could cause operational
proble s with your syste or ther ostat.
■Push excess wire back into hole to prevent interference with ounting of the ther ostat cover.
■Make sure the Function Switch is set at OFF, and the FAN-AUTO Switch is in AUTO.
■Insert the botto tab on the ther ostat body into the slot at the botto of the wallplate.
Press top of the ther ostat 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
arked on the unit.
■Switch on the ain power. Press the reset button.
(See Figure 5.)
■The LCD display indicates the current roo te perature
of your house. If it shows rando nu bers or partial
digits, press the reset button once again.
