Read This Before Installing Thermostat
IMPORTANT
1Read the entire installation section of this Owner’s Manual thoroughly before you begin to install or oper-
ate your Hunter Thermostat.
Remove the Mylar label from the LCD display window.
INSTALLATION
2All installation is normally performed at your thermostat.
ARMCHAIR PROGRAMMING
3You 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.
SYSTEM COMPATIBILITY
4Your 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 the United States.
This thermostat will not control 120/240 Volt systems or
millivolt systems.
COMPRESSOR PROTECTION
5The thermostat provides a 3.5 minute delay after shut- ting o the heating or cooling system before it can be
restarted. This feature will prevent damage to your com-
pressor caused by rapid cycling.

6
TEMPERATURE RANGE
6Your 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 displayed if the temperature is lower than
15°F (-9°C).
AUTO RECOVERY
7Your thermostat is set from the factory to gradually recover the room temperature from an energy saving
program to your comfort program. Therefore, the ther-
mostat may turn your system on several minutes prior to
your programmed time. This operation is normal, but can
be turned o. Refer to the Options Menu information on
pages 16.
OPERATION
8NOTE: The INDIGLO®Night-Light will not function when the battery power is low.
BATTERY WARNING
9Two fresh AA alkaline batteries should provide well over one year of service. However, when the batteries
become drained, the Low Battery Indicator will ash on the
display. when this message occurs, install new alkaline bat-
teries. You have appoximately one minute to change the
batteies and keep the thermostat’s clock and program set-
tings. Once the batteries have become too low to ensure
proper operation, your system will be turned o, and the
display will be cleared except for the ashing Low Battery
Indicator on the LCD display.
CAUTION: When only the battery Icon ashes on the display, the display, the thermostat is shut down and your
system will no longer operate. In this condition, there is no

REMOTE SENSORS (does not apply to thermostat model
44660)
1Your thermostat can support 3 remote sensors that will measure the temperature from three dierent
locations - two indoor and one outdoor. To congure your
thermostat to work with the remote sensors, follow the
instructions for Sensor Channel selection on page 14 of
this manual. To congure the remote sensors, consult the
Remote Sensor Instruction Manual.

What You Need
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.
CAUTION: Do not remove any wiring from existing thermo-
stat before reading the instructions carefully. WIRES MUST
BE LABELED PRIOR TO REMOVAL.
■ IMPORTANT! Turn o 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
rst be removed. Once wall mounting plate is exposed, look
for wires.
Ifwiresarenotvisible,they maybeconnectedtothebackofthe
wallplate. Again, look for screws, tabs, etc. Some models have
doors that open to expose wires and mounting screws. (See
Figure 1).

Wire Labeling
■ Each wire coming from the wall to the existing thermo-
stat 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, AP-
PLY THE SELF-ADHESIVE LABELS PROVIDED TO THE WIRE
AS SHOWN IN TABLE A and B ON PAGES 12-13. (For ex-
ample, 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.
■ 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.

INSTALLATION
Mount Wallplate and Thermostat
■ 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 opening. Insert mounting screws provided into wall
anchor and tighten. (See Figure 3.) holes until ush with
wall.
■ Reposition wallplate to wall, pulling wires through large
opening. Insert provided mounting screws into wall an-
chors and tighten.

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 during summer you can reduce your fuel bill
up to 25%.
Your thermostat is capable of holding up to 4 separate pro-
grams for each day of the week.
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
program time period.
Your Hunter thermostat is pre-programmed to meet the
ENERGY STAR®guidelines for energy eciency.
■ At power-up or after a reset, all 7 days of the week have these default programs:
Temperature in F° (C°)
Program Number Time Heat Cool
1 6:00am 68°F (20°C) 78°F (26°C)
2 8:00am 60°F (16°C) 85°F (29°C)
3 4:00pm 68°F (20°C) 78°F (26°C)
4 10:00pm 60°F (16°C) 82°F (28°C)
■ The following sections describe how to change these programs.
