Congratulations!
Your new Hunter thermostat will provide years of reliable service. By saving energy,
your thermostat will pay for itself during its first season of use. Thank you for buying
a Hunter product!
Please read this manual for complete instructions on installing and operating your thermo-
stat. If you require further assistance, call Hunter Technical Support at 1-866-268-1936 from
8am to 5pm Central Time.
Before starting, remove the mylar label from the LCD display.
IMPORTANT INFORMATION
1. This thermostat is designed to work on the following systems:
Gas - Standing Pilot Electric Furnace
Gas - Electronic Ignition Electric Air Conditioning
Gas - Fired Boilers
Gas - Milivolt Systems This thermostat will NOT control single-stage or
Oil - Fired Boilers multi-stage heat pumps or 110/220 V baseboard
Oil - Fired Furnace electric heating systems.
2. Temperature Range
This thermostat can be programmed between 7˚C and 35˚C (45˚F and 95˚F). It will display
room temperatures from 0˚C and 37˚C (30˚F to 99˚F). "HI" will be displayed if the tempera-
ture is higher than 37˚C (99˚F), and "LO" will be displayed if the temperature is lower than
0˚C (30˚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 4˚C (40˚F).
3. Compressor Protection
This thermostat provides a 3.5 minute delay after shutting off the cooling system
before it can be restarted. This feature will prevent damage to your compressor
caused by rapid cycling. It does not prevent a rapid compressor restart due to short
power outages.
4. Battery Warning
Two fresh AA alkaline batteries should provide well over one year of service. However,
when the batteries become drained, the Low Battery Indicator will flash on the display.
When this message occurs, install new alkaline 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 flashing Low Battery Indicator on
the LCD display.
CAUTION: When only the battery icon flashes on the display, the ther-
mostat is shut down, and your system 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.

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.
■ Slotted Screwdriver(s)
■ Small Philips 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 and thermostat. See Figure 1. Some thermostats will
have screws or other locking devices that must first be removed. Once the 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 below.
■ 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 thermo-
stat 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 BELOW. (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.

NOTE: Do not connect a "Common" wire (sometimes labeled "C") to any terminal
on this thermostat. Tape up the wire and do not use. This wire provides electricity
to non-battery powered thermostats.
Mount Wallplate and Thermostat
■ Remove the wallplate from your thermostat by pressing the release tab on the bottom of
the thermostat. See Figure 2.

Hold / Return Key: Used for

normal display from Day & Time
setting, Programming, or Span
setting modes.
NOTE: 5-wire Systems
If your thermostat has one wire marked R or RH (2, 3, or 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.
Connect Wires and Mount Thermostat to Wallplate
■ Match and connect the labeled wires to the appropriate 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.
■ 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 interference when installing the thermo-
stat 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.

Selector Switches
In order for this thermostat to control your system, the system type must be specified by the
selector switches on the printed circuit board inside the thermostat.
■ 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 after installation. If the Fan operation is normal,
leave it in the "HG" position. If the Fan does not come on within a minute of the thermo-
stat 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

■ 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
slide the switch to the DISABLE position.
