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 thermostat. If
you require further assistance, call Hunter Technical Support at 1-888-830-1326 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 45˚F and 95˚F (7˚C and 35˚C). It will display room
temperatures from 30˚F to 99˚F (0˚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 30˚F (0˚C).
This thermostat will automatically cut-off in Heat mode if the temperature rises above 95˚F
(35˚C), and automatically cut-off in Cool mode if the temperature drops below 40˚F (4˚C).
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 thermostat
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 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 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.

Wire Labeling (Continued)
■ 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.

■ Position wallplate on wall and pull existing wires through large opening. Then level for ap-
pearance. Mark holes for plastic anchors provided, if your existing holes do not line up with
those on the Hunter wallplate.
■ 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.
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 opera-
tional problems with your system or thermostat.
■ Push excess wire back into the hole to prevent interference 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.
Mount Wallplate and Thermostat
■ Remove the wallplate from your thermostat by pressing the release tab on the bottom of the
thermostat. See Figure 2.
