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 multi-

stage 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.

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

and 37°C).

POWER FAILURE

Whenever the main power is interrupted or

fails, the battery power retains the programs

and current time.

This thermostat is designed to optimize the use of your heating and cooling equipment. It

does this by matching your comfort (the temperatures in your home) to your schedule.

An example:

6:00 am – You wake up. Program 1 has the heat set to 70° (21°C).

7:30 am – You leave for work. The second program turns the heat back to 62° (17°C)

while you are away.

5:00 pm – You come home. The third program has already warmed your house back

to 70° (21°C).

10:00 pm – You go to bed. A half hour later, program 4 turns the heat back to 64° (18°C)

to save energy while you are under the blankets.

How This Thermostat Works…And Saves You Money

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.

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

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).

■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 11.

■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, APPLY THE SELF-ADHESIVE LABELS

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 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

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.
