Congratulations!

Your new Climate Technology 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 Climate Technology product!

Please read this manual for complete instructions on installing and operating your thermostat. If you require further assistance, call Climate Technology Technical Support at 1-800-676-7861 from 8am to 5pm Central Time.

IMPORTANT INFORMATION

1. This thermostat is designed to work on the following systems:

Gas - Standing Pilot Single Stage Heat Pumps - with no auxiliary heat Gas - Electronic Ignition Electric Furnace Gas - Fired Boilers Electric Air Conditioning Gas - Milivolt Systems Oil - Fired Boilers This thermostat will NOT control multi-stage heat pumps Oil - Fired Furnace 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.

ENERGY STAR® PARTNER

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.

Typical Home Thermostats

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 bat-

tery condition.

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 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.

(Continued)

Page 3

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.

■ If your system is a single stage heat pump and uses an O or B wire, you must move the Sys-

tem Selector switch inside the thermostat to the Heat Pump position. If you have a normal furnace or electric system, leave the switch in the Standard position. Refer to the System Selector section on the back for more information on this switch.

■ 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.

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 nonbattery 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.

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 thermostat 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 electric systems having a fan relay.

■ System Selector (STANDARD - HEAT PUMP switch)

The factory position for this switch is in the STD position. Leave it in this position if you have ANY system that uses gas, oil, electric, or hot water heating. If you have a single-stage Heat Pump (no auxiliary or emergency heat source), then slide the switch to the HP position. Be sure the reversing valve wire is connected to the correct terminal for your heat pump (Y/O) or (W/B).

■ 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

Program. If you prefer to use normal recovery, slide the

switch to the DISABLE position.

Backlighting (INDIGLO® Night-Light)

Your thermostat has an electroluminescent lamp that backlights the display for easy viewing in the dark.

When any key is pressed or the System Switch is changed, the display is illuminated. The display will remain illuminated for 5 seconds after the last key is pressed. This allows the

light to stay on if you need to operate several keys.

Note: If the thermostat is in Low Battery warning condition, the backlight will not operate. Replace with 2 new alkaline batteries to restore the Backlight function.

Low Battery Warning

Your thermostat has a two-stage low battery warning system. When the batteries are first detected to be weak, the first stage low battery warning is indicated by battery symbol flashing on the LCD display. At your earliest convenience, you need to replace the batteries with 2 new AA alkaline batteries.

When the batteries become too weak for normal operation, the thermostat enters the second stage low battery warning which shuts down the thermostat. In this condition, “BATT” flashes alone on the display, and the thermostat will turn your system Off. Your system will remain shut-off until the batteries are replaced.

Note: The thermostat will still keep the current time and your programs in memory until new batteries are installed. After confirming that new batteries have been inserted, the thermostat will return to normal operation.
