Read This Before Installing Thermostat

IMPORTANT

Read the entire installation section of this

Owner’s Manual thoroughly before you begin

to install or operate your Hunter Thermostat.

• Remove the mylar label from the display window.

INSTALLATION

All installation is normally performed at your

thermostat.

PROGRAMMING

You can practice programming before

installing your thermostat by inserting and connecting the batteries and following the instructions on page 14. This can be done while you relax in your favorite chair and is a very good way to familiarize yourself with all the functions of your Hunter Thermostat.

OPERATION

Your Hunter Thermostat is designed to

operate with most gas, oil, electric or 2-wire hot water heating, and air conditioning systems that have 24-volt or millivolt control.

This Hunter Thermostat will not control multistage heating or cooling systems, 110/220 V systems, or 3 wire zone systems.

COMPRESSOR PROTECTION

The thermostat provides a 4-minute delay

after shutting off the compressor before it can be restarted. This feature will prevent damage to your air conditioner compressor caused by rapid cycling. It does not provide a delay when there are power outages.

Page 5

TEMPERATURE RANGE

Your thermostat can be programmed between

40°F and 95°F (5°C and 35°C). However, it will display room temperatures from 32°F to 99°F (0°C to 37°C).

POWER FAILURE

Whenever the main power is interrupted or

fails, the battery power retains the programs and current time.

BATTERY WARNING

When the batteries are low the “LOW BATT”

indicator on the display will flash. When this happens, install new batteries immediately. Once the “LOW BATT” indicator appears, the thermostat will continue to operate for

approximately 30 days. (Only alkaline batteries should be used in your thermostat. Rechargeable batteries have different properties which may cause the thermostat to not operate properly. Do not use old batteries.) The batteries should last one year.

CAUTION: The batteries are the only source of power used to operate your system. If you do not replace the batteries, the display will dim and your heating and cooling system will stop operation.

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.

What You Need

This thermostat comes with two #8 slotted screws and two wall anchors for mounting. To install your unit, you should have the following tools and materials.

■ Slotted screwdriver ■ Electric drill and 3/16" bit

■ Hammer ■ Two 1.5V (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 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).

Label Wires

■ 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 on page 9.

■ 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.

Do not worry, 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, APPL

PROVIDED TO THE WIRE AS SHOWN IN TABLE A ON PAGE 11. (For example, attach the label marked W to the wire which goes to the W or H terminal on your existing thermostat.) IGNORE THE COLOR OF THE WIRES

■ After labeling wires, disconnect them from the existing

thermostat terminals.

■ Remove existing wallplate. To make sure wires do not fall back

■ If hole in wall is larger than necessary for wires, seal this hole so

into wall opening, you may want to tape them to the wall.

that no hot or cold air can enter the back of the thermostat from the wall. This air could cause a false thermostat reading.

since these do not always comply with the standard.

Wire Labeling

This table will help you match the labels to the wires so you can attach them to your Hunter Thermostat.

NOTE: Follow the labels when connecting wires since many installations do not follow color coding of wires.

Wire Labeling (Continued)

NOTE: If your thermostat has one wire marked R or RH (4-wire system), then leave the

jumper wire between the RH and RC terminals. Otherwise, if you have separate RH and RC wires (5-wire system), then remove the jumper wire between the RH and RC terminals.

NOTE: Do not connect a “Common” wire (sometimes labelled “C”) to any terminal on this thermostat. Tape up the wire and do not use.

Page 13

Mount Wallplate and Thermostat

Snap open the wallplate from your thermostat by pressing the release tab on the bottom of the thermostat.

Position wallplate on wall and pull existing wires through large opening. Then level for appearance. Mark holes for plastic anchors provided if existing holes do not line up with Hunter Thermostat holes.

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 2.)

Selector Switches

The heating system selector and the F°/C° selector switches are located on the Printed Circuit Board.

■ Heating system selector

The heating system selector is a switch on the Printed Circuit Board on the inside of the thermostat. The switch is at “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. Leave the switch in the “HG” position. If the fan does not come on when the thermostat calls 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.

■ F°/C° selector (Fahrenheit/Centigrade)

Your thermostat is set for F° mode from the factory. In order to change to C° mode, slide the switch to C° and press reset button on the front of the thermostat with a paper clip. The reset button is located near the display.

NOTE: Unless reset button is pressed, the thermostat will not change the mode.

Connect Wires and Mount Thermostat Cover to Wall Plate

■ Match and connect the labeled wires to the appropriate coded terminal screws on the

mounting plate. (See Figure 3, 4.) Ignore any wires which may be present, but which were not connected to the old thermostat.

problems with your system or thermostat.

■ Push excess wire back into hole to prevent interference with mounting of the thermostat cover.

■ Make sure the Function Switch is set at OFF, and the FAN-AUTO Switch is in AUTO.

■ Insert the bottom tab on the thermostat body into the slot at the bottom of the wallplate.

Press top of the thermostat body to snap it into the wallplate. (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 batteries, observing the polarity

marked on the unit.

■ Switch on the main power. Press the reset button.

(See Figure 5.)

■ The LCD display indicates the current room temperature

of your house. If it shows random numbers or partial digits, press the reset button once again.

■ The installation is now complete. Continue reading

Start-Up

When you first install two AA size batteries, as directed in the installation instructions, press the Reset Button.

■ The thermostat is preset at the factory to 68°F (20°C) for heat and 78°F (25°C) for cool.

■ Room temperature is displayed.

■ Your thermostat batteries will prevent memory loss and avoid reprogramming. Replace

batteries as soon as low battery indicator comes on the display.

■ A built-in timer prevents damage to your air conditioner compressor, caused by rapid cycling,

by providing a delay of 4 minutes before it will restart.

■ The thermostat will display room temperature from 32°F to 99°F. (0°C to 37°C).

■ The temperature can be set from 40°F to 95°F. (5°C to 35°C).
