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
2
All installation is nor ally perfor ed at your
ther ostat.
PROGRAMMING
3
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
4
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
5
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
6
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
7
Whenever the ain power is interrupted or
fails, the battery power retains the progra s
and current ti e.
BATTERY WARNING
8
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.
