Read This Before Installing Thermostat
IMPORTANT
Read the entire installation section of this Owner’s Manual
thoroughly before you begin to install or operate your
Hunter Thermostat.
1
Remove the Mylar label from the LCD display window.
INSTALLATION
All installation is normally performed at your
thermostat.
2
ARMCHAIR PROGRAMMING
You 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.
6
SYSTEM COMPATIBILITY
Your Thermostat is designed to operate these
24-Volt systems:
4
■ Multi-stage heat pumps with auxiliary heat
■ Single-stage heat pumps
■ 2, 3, or 4 wire gas, oil, and electric furnaces and air conditioning systems
This thermostat will not control 120/240 Volt systems or
millivolt systems.
3
COMPRESSOR PROTECTION
The 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.
TEMPERATURE RANGE
Your 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).
BATTERY WARNING
Fresh alkaline batteries will provide over one year of memory
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.
5
7
6
AUTO RECOVERY
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 Options
Menu information on pages 16.
7
OPERATION
This system operates on your system’s 24 Volt power supply.
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.
8
NOTE: The INDIGLO® Night-Light will not function when
AC power is lost.
9
NOTE: The default system selection at power-on is HEAT.
Batteries are recommended to prevent an undesired system change due to a power outage.

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.
■ Slotted Screwdriver(s)
■ Phillips Screwdriver
■ Hammer
■ Electric drill and 3/16" bit
■ Two 1.5 V (AA) size alkaline batteries
Remove Old Thermostat
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 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 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
11
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.

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 programs
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 efficiency.
■ At power-up or after a reset, all 7 days of the week have these default programs:

Auto Season Changeover
When the System Selection is in AUTO position, the thermostat
will automatically change between Heating and Cooling systems,
depending on your program. We recommend keeping your programmed heating and cooling temperatures at least 5°F (3°C)
apart to allow the Auto Season Changeover to occur when the
appropriate temperature span has been reached. However, if
your heating and cooling programs set temperatures are close,
there is a built-in program to prevent the thermostat from
changing unnecessarily.
Auto Season Changeover is disabled when the thermostat is in
Temporary or Permanent Override, or Vacation Hold, as these
overrides are energy saving settings. While in any of these
modes, “AUTO” will be temporarily removed form the LCD dis-
39
play. “AUTO” will return when these holds are cleared. Auto Season Changeover will still function in Home Today mode, as this is
a comfort setting.
For example, you may have the following temperatures programmed at a given time:
Heat Set Temp = 68°F
Cool Set Temp = 78°F
If the room temperature rises above 78°F, then the thermostat
will automatically change to cool mode and turn on the air
conditioner.
Likewise, the thermostat will automatically change to heat mode
and turn on heat when the room temperature falls below 68°F.

SPAN Settings
STAGE 1
Your thermostat is set at the factory to cycle at 1°F (0.5°C)
above and below the set temperature in Stage 1. (Span = 2.) This
setting has been designed to provide a comfortable room temperature under most all conditions. However, if you find your system cycling too fast or too slow, then the Span can be adjusted
to modify the cycle time. Refer to the Option Menu Stage 1 Span
selection on page 17.
The Span settings remain the same for both HEAT and COOL.
The Span can be changed at any time and is independent of program times or temperatures.
When the thermostat is powered on or the Reset key is pressed,
the Span is reset back to setting 2.
Span = 1. This decreases the cycle time by causing your
system to run shorter.
Span = 3. This increases the cycle time by causing your
system to run longer.

Auto Recovery
45
Hunter’s Auto Recovery feature meets the ENERGY STAR® guidelines for energy efficiency by allowing the heating or cooling system to recover gradually from an energy-saving setpoint temperature to a comfort setpoint temperature.
Auto Recovery calculates how early to turn your system back On,
so that the room temperature is already comfortable by the start
of the comfort temperature program period. Auto Recovery
works in both Heat and Cool modes.
For example, in Heat mode, you could have the following
programs:
Program #4 (Overnight)
Set Temp = 60°F
Time = 10PM
Program #1 (Morning)
Set Temp = 68°F
Time = 6AM
The room temperature fell to 60°F overnight. Rather than having
the thermostat turning on at 6AM, Auto Recovery would note
the temperature difference between 60°F and 68°F and turn the
Heat on approximately 30 minutes early. Therefore, the room
temperature at 6AM would be about 68°F instead of 60°F.
■ When the thermostat is
in Auto Recovery mode,
the display will alternate
“RECOVERY” with the
day, and the program
indicator will flash.

also not operate if the thermostat resets due to AC power loss
with no backup batteries.
■ Auto Recovery can be canceled manually if RET CLEAR is
pressed during the recovery process. If a recovery process is
canceled manually then the recovery process will not start
again until the next program period starts (an exception is
that if time or program is changed then the thermostat will
check Auto Recovery conditions immediately).
