Read This Before Installing Thermostat
IMPORTANT
Read the entire installation section of this Owner’s Manual
1
thoroughly before you begin to install or operate your
Hunter Thermostat.
Remove the Mylar label from the LCD display window.
INSTALLATION
All installation is normally performed at your
2
thermostat.
ARMCHAIR PROGRAMMING
You can program your thermostat before installation by in-
3
serting 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
Your Thermostat is designed to operate these
4
24-Volt systems:
■ Multi-stage heat pumps with auxiliary heat
■ Single-stage heat pumps
This thermostat will not control 120/240 Volt systems or
millivolt systems.
COMPRESSOR PROTECTION
The thermostat provides a 3.5 minute delay after shutting off
5
the heating or cooling system before it can be restarted.
This feature will prevent damage to your compressor caused
by rapid cycling.
6
7
TEMPERATURE RANGE
Your thermostat can be programmed between 45°F and 95°F
6
(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
Your thermostat is set from the factory to gradually recover
7
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 Options
Menu information on pages 16.
OPERATION
This system operates on your system’s 24 Volt power supply.
8
The supply is monitored by the thermostat, and it will stop
functioning if AC power is lost. (When using backup batteries,
“No AC Pwr” will be displayed.) All system controls will remain
off until power is restored.
The INDIGLO® Night-Light will not function when
NOTE:
AC power is lost.
BATTERY WARNING
Fresh alkaline batteries will provide over one year of memory
9
backup and clock operation. However, when the batteries
become drained, a low battery warning will appear on the display. When this message occurs, install 2 new AAA batteries. You
have approximately 30 seconds when changing the batteries to
keep thermostat’s clock and program settings.
The default system selection at power-on is HEAT.
NOTE:
Batteries are recommended to prevent an undesired system change due to a power outage.

INSTALLATION
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.
Remove Old Thermostat
CAUTION:
mostat before reading the instructions carefully. WIRES
MUST BE LABELED PRIOR TO REMOVAL.
■
■
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).
Do not remove any wiring from existing ther-
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,

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 the next page.
■
The number of wires in your system can be as few as four
(for single-stage 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.
■
IMPORTANT! BEFORE DISCONNECTING ANY WIRES, APPLY
THE SELF-ADHESIVE LABELS PROVIDED TO THE WIRE AS
SHOWN IN TABLE A and B ON PAGES 12-13. (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.
■
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.

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.
Figure 2 Figure 3
■
Drill holes with 3/16" bit and gently tap anchors into the
holes until flush with wall.

maximum. Insert each labeled wire into the bottom of the
maching terminal. Refer to figures 4 and 5.
■
Hold the wires in each terminal and tighten the terminal
screws securely, otherwise a loose wire could cause operational problems with your system or thermostat.
■
Push excess wire back into hole to prevent interference with
mounting of the thermostat.
■
Make sure the Power Switch is set to OFF.
■
Insert two AAA size alkaline batteries, observing the polarity
marked on the unit.
■
Insert the upper tabs on the thermostat body into the slot at
the top of the wallplate. Press bottom of the thermostat body
