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
Oil - Fired Boilers
This thermostat will NOT control single-stage or multi-stage
Oil - Fired Furnace
heat pumps or 110/220 V baseboard electric heating
systems.
2. Temperature Range
This thermostat can be programmed between 45°F and 95°F (7°C and 35°C).
However, 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
45°F (7°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: 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.
FEATURES
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.

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
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.

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.
■
Note that this thermostat has multiple function terminals that allow Single-Stage
Heat Pump capability. Standard systems use: Rh, Rc, G, Y, W. [Single-Stage Heat
Pumps use: Rc, 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 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.
■
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.
Table A
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.
■
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.
■
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.

existing thermostat is

with label shown
