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 Ther ostat.

• Re ove the ylar label fro the display

window.

INSTALLATION

All installation is nor ally perfor ed at your

ther ostat.

PROGRAMMING

You can practice progra ing before

installing your ther ostat 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 fa iliarize yourself with all the

functions of your Hunter Ther ostat.

OPERATION

Your Hunter Ther ostat is designed to

operate with ost gas, oil, electric or 2-wire

hot water heating, and air conditioning syste s

that have 24-volt or illivolt control.

This Hunter Ther ostat will not control ulti-

stage heating or cooling syste s, 110/220 V

syste s, or 3 wire zone syste s.

COMPRESSOR PROTECTION

The ther ostat provides a 4- inute delay

after shutting off the co pressor before it

can be restarted. This feature will prevent

da age to your air conditioner co pressor

caused by rapid cycling. It does not provide a

delay when there are power outages.

511/41251/book p. 1-15 2/8/01 2:24 PM Page 4

TEMPERAT RE RANGE

Your ther ostat can be progra ed between

40°F and 95°F (5°C and 35°C). However, it will

display roo te peratures fro 32°F to 99°F (0°C

to 37°C).

POWER FAIL RE

Whenever the ain power is interrupted or

fails, the battery power retains the progra s

and current ti e.

BATTERY WARNING

When the batteries are low the “LOW BATT”

indicator on the display will flash. When this

happens, install new batteries i ediately.

Once the “LOW BATT” indicator appears, the

ther ostat will continue to operate for

approxi ately 30 days. (Only alkaline batteries

should be used in your ther ostat.

Rechargeable batteries have different properties

which ay cause the ther ostat to not operate

properly. Do not use old batteries.) The batteries

should last one year.

CA TION: 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.

Installation

■Each wire co ing fro the wall to the existing ther ostat is connected to a ter inal point on

that ther ostat. Each of these ter inal points is usually arked with a code letter as shown in

Table A on page 9.

■The nu ber of wires in your syste can be as few as two (for heat only syste s), as any as

eight, or any nu ber in between. If you follow the labeling procedures correctly, you do not

have to be concerned about how any wires there are.

■There is often no ter inal arking on the existing ther ostat of two wire, heat only syste s.

Do not worry, just connect either of the wires to the RH ter inal, then connect the other wire

to the W ter inal to co plete 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 exa ple, attach the

label arked W to the wire which goes to the W or H ter inal on your existing ther ostat.)

IGNORE THE COLOR OF THE WIRES since these do not always co ply with the standard.

■After labeling wires, disconnect the fro the existing

ther ostat ter inals.

■Re ove existing wallplate. To ake sure wires do not fall back

into wall opening, you ay want to tape the 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 ther ostat

fro the wall. This air could cause a false ther ostat reading.
