IMPORTANT
1
Read the entire installation section of this Owner’s
Manual thoroughly before you begin to install or
operate your Hunter Thermostat.
REMOVE THE MYLAR LABEL FROM THE LCD DISPLAY WINDOW.
INSTALLATION
2
All installation is normally performed at your
thermostat.
ARMCHAIR PROGRAMMING
3
Y
ou can program your thermostat before installation 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.
Note: At initial power-up this thermostat is programmed at 68°F
(20°C) for Heat and 78°F (26°C) for Cool. Any change to the set
temperature will be treated as a Permanent Manual Override. See
page 25 for more information. Press Auto Program to load the
built-in energy saving programs.
OPERATION
4
Y
our Thermostat is designed to operate with most 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, air conditioning, or space
heating units in use in the United States.
This Hunter Thermostat will NOT control multi-stage heat
pumps or 110/220 Volt systems.
COMPRESSOR PROTECTION
5
T
he thermostat provides a 3.5 minute delay after
shutting 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
provide a delay when there are power outages.
TEMPERATURE RANGE
6
Y
our thermostat can be programmed between 40°F
and 95°F (4°C and 35°C). However, it will display room
temperatures from 32°F to 99°F (0°C and 37°C). “HI” will
be displayed if the temperature is higher than 99°F (37°C),
and “LO” will be displayed if the temperature is lower than
32°F (0°C).
NOTE: The thermostat will automatically change to the Cool
mode if the thermostat measures a temperature over 99°F
(37°C). “Hi” will be displayed on the LCD, and the Cooling
system will turn On. Similarly, the thermostat will
automatically change to the Heat mode if the temperature is
below 32°F (0°C). “LO” will be displayed on the LCD, and the
Heating system will turn On.

POWER FAILURE

W
henever the main power is interrupted or fails, the
battery power retains the programs and current time.
AUTO RECOVERY
8
Your thermostat is set from the factory to gradually recover
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 Selector Switches information on pages 14-15.
BATTERY WARNING
9
F
resh alkaline batteries should provide over one year of
service. However, when the batteries become drained,
“BATT” will alternate on the display with the current time.
When this message occurs, install 2 new AA batteries. You
have approximately 1 minute to 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 “BATT” flashing on the LCD display.
CAUTION: Once the “BATT” only display occurs, the
thermostat is shut down, and your system will no longer
operate. In this condition, there is no temperature control of
your dwelling.
NOTE: The INDIGLO
®
night-light will not function when the
thermostat is in low battery condition.
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 thermostat includes two #8 slotted screws and two wall
anchors 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
What You Need
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. 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 wir
es.
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).

■ 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 this page.
■ 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. 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 THIS PAGE. (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.
■ 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
If the code letter on your
existing thermostat is
then mark the wire
with label shown
and connect to thermostat
terminal shown
NOTE: Do not connect a “Common” wire (sometimes labeled “C”) to any terminal on this thermostat. Tape up the wire and
do not use. This wire provides electricity to non-battery powered thermostats.

■
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.)

INSTALLATION
Mount Wallplate and Thermostat
NOTE: 5-wire Systems
If your thermostat has one wire marked R or RH (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.
