Read This Before Installing Thermostat
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
You 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.
OPERATION
4
Your 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
The 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 prevent a rapid compressor re-
start due to short power outages.
TEMPERATURE RANGE
6
Your thermostat can be programmed between
45°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 dis-
played if the temperature is lower than 32°F (0°C).
This thermostat will automatically cut off in Heat
mode if the temperature rises above 95°F (35°C),
and automatically cut off in cool mode if the tem-
perature drops below 45°F (7°C).
