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 PilotSingle-Stage Heat Pumps - with no auxiliary heat
Gas - Electronic IgnitionElectric Furnace
Gas - Fired BoilersElectric Air Conditioning
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). 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: 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 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 screwdriverHammerElectric drill and 3/16” bitTwo 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.

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 terminal marking on the existing thermostat of

two wire, heat only systems. Just connect either of the wires to the

W

G Y

RH terminal, then connect the other wire to the W terminal to

RH

complete the circuit.

 

RC

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.
