Read This Before Installing Thermostat

IMPORTANT

Read the entire installation section of this
Owner’s Manual thoroughly before you begin

1

to install or operate your Hunter Thermostat.
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

3

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.

OPERATION

Your Thermostat is designed to operate with
most gas, oil, electric or 2-wire hot water heating

4

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 use in the
United States.

This Hunter Thermostat will NOT control multi­stage heat pumps or 110/220 Volt systems.

COMPRESSOR PROTECTION

The thermostat provides a 3.5 minute delay after
shutting off the heating or cooling system before

5

it can be restarted. This feature will prevent damage
to your compressor caused by rapid cycling. Note
that this delay also applies to the heating system
control. It does not prevent a rapid compressor re­start due to short power outages.

TEMPERATURE RANGE

Your thermostat can be programmed between
4°C and 35°C (45°F and 95°F). However, it will

6

display room temperatures from 0°C and 37°C (32°F
to 99°F). “HI” will be displayed if the temperature is
higher than 37°C (99°F), and “LO” will be displayed
if the temperature is lower than 0°C (32°F).

This thermostat will automatically cut off in Heat
mode if the temperature rises above 35°C (95°F),
and automatically cut off in cool mode if the tem­perature drops below 7°C (45°F).

POWER FAILURE

Whenever the main power is interrupted or fails,
the battery power retains the programs and cur-

7

rent time.

AUTO RECOVERY

Your thermostat is set from the factory to gradually
recover the room temperature from an energy sav-

8

ing 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 Selector
Switches information on page 24.

BATTERY WARNING

Fresh alkaline batteries should provide over one
year of service. However, when the batteries be-

9

come drained, the Low Battery indicator will flash on
the display. When this message occurs, install 2 new
AA batteries. You have approximately 1 minute to

change the batteries and keep thermostat’s clock and
program settings. Once the batteries have become too
low to ensure proper operation, your system will be
turned Off, and the display will be cleared except for
the Low Battery indicator flashing on the LCD display.

CAUTION:

Once the Low Battery only display oc­curs, the thermostat is shut down, and your sys­tem will no longer operate. In this condition,
there is no temperature control of your dwelling.

NOTE:

The INDIGLO® night-light will not function

when the thermostat is in low battery condition.

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

What You Need

This thermostat includes two #8 screws and two wall
anchors for mounting. To install your thermostat, you
should have the following tools and materials.

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,

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).

look for wires.

■ Phillips and Slotted Screwdrivers

■ Hammer

■ Electric drill and 3/16" bit

■ Two 1.5 V (AA) size alkaline batteries

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.

■ Note that this thermostat has multiple function

terminals that allow Single-Stage Heat Pump ca­pability. Standard systems use: Rh, Rc, G, W.
[Single-Stage Heat Pumps use: Rh, Y1, G, and O or
B.] Table A below shows the multiple functions of
the terminals. Use the terminals that match your
system.

■ 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 ter-

minal marking on the
existing thermostat of
two wire, heat only
systems. 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
THE NEXT PAGE. (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 with insulating material 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.

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.

Figure 2 Figure 3

NOTE: 5-wire Systems

If your thermostat has one wire marked R or RH (4-wire system), then leave the jumper wire between the RH and
RC terminals on the wallplate.

Otherwise, if you have separate RH and RC wires (5-wire system), then remove the jumper wire between the RH
and RC terminals.

■ Drill holes with 3/16” bit and gently tap anchors

into the holes until flush with wall.

■ Reposition wallplate to wall, pulling wires through

large opening. Insert mounting screws provided
into wall anchor and tighten. (See Figure 3.)

INSTALLATION

Connect Wires and Mount Thermostat Cover to Wall Plate

■ Match and connect the labeled wires to the appro-

priate coded terminal screws on the wallplate. (See
Figure 4, 5.) Ignore any wires which may be present,
but which were not connected to the old thermostat.

■ Refer to the Wiring Diagrams below to be sure your

system is wired correctly.

■ If your system is a single-stage heat pump and

uses an O or B wire, you must move the System
Selector switch inside the thermostat to the Heat
Pump position. If you have a normal furnace or
electric system, leave the switch in the Standard
position. Refer to the System Selector section on
the back for more information on this switch.

■ Be sure to tighten the terminal screws securely,

otherwise a loose wire could cause operational
problems with your system or thermostat.

■ Push excess wire back into the hole to prevent interfer-

ence when installing the thermostat to the wallplate.

■ Make sure the System Switch is set to OFF, and the

Fan Switch is set to AUTO.

■ Insert the bottom tab on the thermostat body into

the slot at the bottom of the wallplate. Press the
top of the thermostat body to snap it into the
wallplate. Refer to Figure 6. (NOTE:

Do not force

the thermostat onto the wallplate, as the ter­minal pins may be damaged. If it does not
snap properly, the thermostat may not work.

■ Insert the two AA size alkaline batteries, observing

the polarity marked inside the battery compartment.

■ Switch on the main power at the panel or furnace.

Selector Switches

In order for this Hunter thermostat to control your
system, the system type must be specified by se­lector switches on the printed circuit board inside
the thermostat.

NOTE:

When changing these features after instal­lation, move the HEAT / COOL selector switch
to OFF before removing the thermostat from
the wall.

System Selector Switches:

■ Heating system selector (HG – HE switch)

The factory position for this switch is in the “HG”
position. Leave it in this position if you have a gas
furnace or an oil burner.

If you have an electric furnace, test to see
whether the Heat and Fan come on as expected.

If Fan operation is normal, leave the switch in the
“HG” position.

If the Fan does not come on within a minute of
the thermostat calling for Heat, change the switch
position to “HE.”

The system selector has no effect in the cool­ing mode.

NOTE:

“HG” position is for gas and most
other systems. “HE” position is for certain
electric systems having a fan relay.

■

Furnace or Heat Pump selector (STD - HP switch)

The factory position for this switch is in the STD
position. Leave it in this position if you have ANY
system that uses gas, oil, electric, or hot water heating.

If you have a single-stage Heat Pump (no auxiliary
or emergency heat source), then slide the switch to
the HP position.

■ Auto Recovery selector (DISABLE / ENABLE)

Your thermostat is set from the factory with the Auto
Recovery Feature enabled, which complies with the
EPA ENERGY STAR
normal recovery, slide the switch to the ALT position.

Refer to page 32 for a complete discussion of the
Auto Recovery feature.
