Read This Before Installing Thermostat
IMPORTANT
Read the entire installation section of this
1
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
2
thermostat.
PROGRAMMING
You can practice programming before
3
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
4
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
5
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
6
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
7
fails, the battery power retains the programs
and current time.
BATTERY WARNING
When the batteries are low the “LOW BATT”
8
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.

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).
