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 Thermostat.
• Remove the mylar label from the display
window.
INSTALLATION
2
All installation is normally performed at your
thermostat.
PROGRAMMING
3
You can practice programming before
installing 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.
OPERATION
4
Your Hunter Thermostat is designed to
operate with most gas, oil, electric or 2-wire
hot water heating, and air conditioning systems
that have 24-volt or millivolt control.
This Hunter Thermostat will not control multi-
stage heating or cooling systems, 110/220 V
systems, or 3 wire zone systems.
COMPRESSOR PROTECTION
5
The thermostat provides a 4-minute delay
after 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.
TEMPERATURE RANGE
6
Your thermostat can be programmed between
40°F and 95°F (5°C and 35°C). However, it will
display room temperatures from 32°F to 99°F (0°C
to 37°C).
POWER FAILURE
7
Whenever the main power is interrupted or
fails, the battery power retains the programs
and current time.
BATTERY WARNING
8
When the batteries are low the “LOW BATT”
indicator 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.
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.
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 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 ■Electric drill and 3/16" bit
■Hammer ■Two 1.5V (AA) Size Alkaline batteries
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).

Installation
■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 9.
■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.
■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.
