Read This Before Installing Thermostat
IMPORTANT
1Read the entire installation section of this Owner’s Manual thoroughly before you begin to install or
operate your Hunter Thermostat.
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 instruc-
tions starting on page 12. 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 shutting off the heating or cooling system before it
can be restarted. This feature will prevent damage to
your compressor 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 tempera-
ture 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 sav-
ing program to your comfort program. Therefore, the
thermostat may turn your system on several minutes
prior to your programmed time. This operation is nor-
mal, but can be turned off. Refer to the Options Menu
information on pages 15.
BATTERY WARNING
8Two fresh AA alkaline batteries should provide well over one year of service. However, when the batter-
ies become drained, the Low Battery Indicator will ash
on the display. when this message occurs, install new
alkaline batteries. You have appoximately one minute
to change the batteries and keep the thermostat’s clock
and program settings. Once the batteries have become
too low to ensure proper operation, your system will
be turned off. The display will be cleared except for the
ashing Low Battery Indicator on the LCD display, and
all programming will be lost.
CAUTION: When only the battery Icon ashes on the display, the thermostat is shut down and your
system will no longer operate. In this condition, there is
no temperature control of your dwelling. 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.

REMOTE SENSORS (does not apply to thermostat
model 44660)
1Your thermostat can support 3 remote sensors that will measure the temperature from three different lo-
cations - 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 13 of
this manual. To congure the remote sensors, consult
the Remote Sensor Instruction Manual.
NOTE (does not apply to thermostat model 44660):
This device complies with Part 15 of the FCC Rules. Op-
eration is subject to the following two conditions: (1) this
device may not cause harmful interference, and (2) this
device must accept any interference received, including
interference that may cause undesired operation.
This equipment has been tested and found to comply with
the limits for a Class B digital device, pursuant to Part 15
of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a
residential installation. This equipment generates, uses
and can radiate radio frequency energy and, if not installed
and used in accordance with the instructions, may cause
harmful interference to radio communications. However,
there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harm-
ful interference to radio or television reception, which can
be determined by turning the equipment off and on, the
user is encouraged to try to correct the interference by
one or more of the following measures:
• Increase the separation between the equipment and
receiver.
• Connect the equipment into an outlet on a circuit dif-
ferent from that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV techni-
cian for help.

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.
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 lock-
ing devices that must rst 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).

Wire Labeling
■ 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.
■ 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 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.
IMPORTANT!
If wires marked Y & C are both present, C may be a
Common wire and should not be used. If you have
a wire marked C, do not connect it to any terminal.
This wire is used only for non-battery powered
thermostats.
■ 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 anchors and tighten.
