IMPORTANT
1
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 LCD DISPLAY WINDOW.
INSTALLATION
2
All installation is normally performed at your
thermostat.
ARMCHAIR PROGRAMMING
3
Y ou can program your thermostat before installation by
inserting the batteries and following the instructions
starting on page 16. 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.
Note: At initial power-up this thermostat is programmed at 68°F
(20°C) for Heat and 78°F (26°C) for Cool. Any change to the set
temperature will be treated as a Permanent Manual Override. See
page 25 for more information. Press Auto Program to load the
built-in energy saving programs.
OPERATION
4
Y our Thermostat is designed to operate with most gas,
oil, electric or 2-wire hot water heating and air
conditioning systems. It will also operate single-stage heat
pumps that do not have auxiliary or emergency heat.
These have 24-volt or millivolt control systems and
represent most central heating, air conditioning, or space
heating units in use in the United States.
This Hunter Thermostat will NOT control multi-stage heat
pumps or 110/220 Volt systems.
COMPRESSOR PROTECTION
5
T he thermostat provides a 3.5 minute delay after
shutting off the heating or cooling system before it can
be restarted. This feature will prevent damage to your
compressor caused by rapid cycling. Note that this delay
also applies to the heating system control. It does not
provide a delay when there are power outages.
TEMPERATURE RANGE
6
Y our thermostat can be programmed between 40°F
and 95°F (4°C and 35°C). However, it will display room
temperatures from 32°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
32°F (0°C).
NOTE: The thermostat will automatically change to the Cool
mode if the thermostat measures a temperature over 99°F
(37°C). “Hi” will be displayed on the LCD, and the Cooling
system will turn On. Similarly, the thermostat will
automatically change to the Heat mode if the temperature is
below 32°F (0°C). “LO” will be displayed on the LCD, and the
Heating system will turn On.

POWER FAILURE
7
W henever the main power is interrupted or fails, the
battery power retains the programs and current time.
AUTO RECOVERY
8
Your thermostat is set from the factory to gradually recover
the room temperature from an energy saving program to
your comfort program. Therefore, the thermostat may turn
your system on several minutes prior to your programmed
time. This operation is normal, but can be turned off. Refer to
the Selector Switches information on pages 14-15.
BATTERY WARNING
9
F resh alkaline batteries should provide over one year of
service. However, when the batteries become drained,
“BATT” will alternate on the display with the current time.
When this message occurs, install 2 new AA 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 “BATT” flashing on the LCD display.
CAUTION: Once the “BATT” only display occurs, 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 battery condition.
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.
