IMPORTANT
air conditioning, or space heating units in use in the
United States.
Read the entire installation section of this
1Owner’s Manual thoroughly before you begin
to install or operate your Hunter Thermostat.
This Hunter Thermostat will NOT control multi-
stage heat pumps or 110/220 Volt systems.
REMOVE THE MYLAR LABEL FROM THE LCD DISPLAY
WINDOW.
COMPRESSOR PROTECTION
The thermostat provides a 3.5 minute delay after
5shutting off the heating or cooling system before
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 re-
start due to short power outages.
INSTALLATION
All installation is normally performed at your
2thermostat.
ARMCHAIR PROGRAMMING
You can program your thermostat before
3installation 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.
TEMPERATURE RANGE
Your thermostat can be programmed between
64°C and 35°C (45°F and 95°F). However, it will
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).
OPERATION
Your Thermostat is designed to operate with
4most 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,
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 tem-
perature drops below 7°C (45°F).

POWER FAILURE
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.
Whenever the main power is interrupted or fails,
7the battery power retains the programs and cur-
rent time.
AUTO RECOVERY
Your thermostat is set from the factory to gradually
8recover 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 Selector
Switches information on page 24.
CAUTION: Once the Low Battery only display oc-
curs, the thermostat is shut down, and your sys-
tem 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.
BATTERY WARNING
Fresh alkaline batteries should provide over one
9year of service. However, when the batteries be-
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

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.
■ Phillips and Slotted Screwdrivers
■ 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 exist-
ing thermostat before reading the instructions
carefully. WIRES MUST BE LABELED PRIOR TO
REMOVAL.
TYPICAL HOME THERMOSTATS
Figure 1
■ 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 first be removed. Once wall
mounting plate is exposed, look for wires.

Wire Labeling
9
■
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.
■ IMPORTANT! BEFORE DISCONNECTING ANY
WIRES, APPLY THE SELF-ADHESIVE LABELS PRO-
VIDED 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.
■ Note that this thermostat has multiple function
terminals that allow Single-Stage Heat Pump ca-
pability. 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.
■ 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 thermo-
stat from the wall. This air could cause a false
thermostat reading.
■ 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 label-
ing procedures correctly, you do not have to be
concerned about how many wires there are.
■ There is often no ter-
minal marking on the
G
Y
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.

Auto Recovery
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.
For example, in Heat mode, you could have the follow-
ing programs:
Program #4 (Overnight)
Set Temp = 16°C
Time = 10pm
Program #1 (Morning)
Set Temp = 20°C
Time = 6am
Auto Recovery calculates how early to turn your sys-
tem 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.
The room temperature fell to 16°C overnight. Rather
than having the thermostat turning on at 6am, Auto
Recovery would note the temperature difference be-
tween 16°C and 20°C and turn the Heat on approxi-
mately 30 minutes early. Therefore, the room tempera-
ture at 6am would be about 20°C instead of 16°C.
■ When the thermostat is in Auto Recovery mode, the display will
alternate RECO with time, and the program indicator will flash.

Details of Auto Recovery Operation:
33
■ Auto Recovery can be disabled by sliding the Re-
covery switch on the circuit board to the DISABLE
position. Refer to page 13.
■ Auto Recovery will be canceled and change to
Home Today mode if HOME TODAY is pressed
during the recovery process.
■ Auto Recovery will not operate if Permanent hold,
Temporary hold or Home Today is in operation.
■ Auto Recovery will be canceled and change to
Temporary Manual Override mode if the setpoint
is adjusted during the recovery process.
■ Auto Recovery can be canceled manually if HOLD/
RETURN is pressed during the recovery process. If a
recovery process is canceled manually then the re-
covery 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).
■ If the system is changed between heat and cool
then the thermostat will recalculate Auto Recov-
ery again. Setpoint temperature will be changed
to the opposite system’s comfort temperature if
the recovery entry criteria are still met. Otherwise,
the recovery process will be canceled and return
to program control mode.

SPAN Setting Mode
Your thermostat is set at the factory to cycle at
0.5˚C (1˚F) above and below the set temperature.
(Span = 2) This setting has been designed to pro-
vide 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.
■ Press and hold BOTH for three seconds. The display
will flash, and SPAN will be displayed on the LCD.
■ Press to raise the Span to 3. This setting INCREASES
the cycle time by allowing your system to run
LONGER.
■ Press to lower the Span to 1. This setting
DECREASES the cycle time by causing your
system to run SHORTER.
41665-01.pmd Download from Www.Som34anuals.com. All Manuals Search9A/3n0/d03D, 5o:w40nPloMad.
The Span settings remain the same for both HEAT
and COOL.
When batteries are installed in the thermostat, or
the Reset key is pressed, the Span is reset back to
setting 2.
The Span can be changed at any time, and is inde-
pendent of program times or temperatures.

with 2 new AA alkaline batteries, even if you have recently replaced
them. Next, use a paper clip to press the RESET button next to the
keypad. You will need to reprogram your thermostat and confirm
normal operation.

mode if the room temperature rises above 35˚C (95˚F).
It will cut-off in Cool mode if the room temperature
drops below 4˚C (40˚F).
NOTE: If your system has malfunctioned and no
longer responds to thermostat controls, the Auto
Cut-Off will have no effect.
