also applies to the heating system control. It does not
provide a delay when there are power outages.
ARMCHAIR PROGRAMMING
ou can program your thermostat before installation by
Y
3inserting 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.
TEMPERATURE RANGE
Your thermostat can be programmed between 40°F
6
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.
OPERATION

Selector Switches
In order for this Hunter thermostat to control your system, the
system type must be specified by selector switches on the printed
circuit board inside the thermostat. There are also other selector
switches that allow you to customize the features to suit your needs.
If you have a single-stage Heat Pump (no auxiliary or
emergency heat source), then slide the switch to the position
that matches your Reversing Valve type. If your heat pump
system has a “B” wire, slide the switch to “B” for your
reversing valve that activates in HEAT mode. If your heat pump
system has an “O” wire, slide the switch to “O” for your
reversing valve that activates in COOL mode.
NOTE: When changing these features after installation, move
the HEAT / COOL selector switch to OFF before removing
the thermostat from the wall.

Auto Programming
Studies conducted by the Department of Energy estimate that
setting your thermostat back 10°F (6°C) for two 8-hour periods
during winter can reduce your fuel bill by as much as 33%. By
setting your thermostat up 5°F (3°C) for two 8-hour periods
during summer you can reduce your fuel bill up to 25%.
to Friday, to the same 4 programs as shown in the table, or each
weekday can have a different set of 4 programs. Similarly weekend
programs, Saturday and Sunday, can be the same 4 programs or
each weekend day can have a different set of 4 programs.
Your Hunter thermostat is pre-programmed to meet the ENERGY
STAR® guidelines for energy efficiency. Note that it is easier to
modify these programs than to program the thermostat manually.
Your thermostat is capable of holding up to 4 separate programs
for each day of the week. You can program all weekdays, Monday

Manual Programming
■ Your thermostat can be programmed for weekdays and
weekends, or have unique programs for all 7 days. Use
Weekday/Weekend Programming below or 7-day Programming
on page 21 to enter or revise programs to match your Personal
Program Schedule. The same steps are used when entering
programs for the first time, or revising programs entered during
Auto Programming.
NOTE: 1) The program time can be set in 10 minute
increments, and remains the same for both Heat
and Cool programs.
2) The program temperature can be set in increments
of 1°F (1°C).
3) The Heat setpoint can not be set higher than the
Cool setpoint, and the Cool setpoint can not be set
lower than the Heat setpoint.
■ When batteries are first installed, the thermostat has all 4 programs
set for 68°F (20°C) in Heat mode and 78°F (26°C) in Cool mode.
4) If the system selector is in AUTO mode, the current
operating mode will be used for programming.
NOTE: There are no energy saving time or temperature
settings until the thermostat is Auto Programmed or
Manually Programmed.
5) After 15 seconds without a key press, the
thermostat will return to normal display mode.
■ Familiarize yourself with Manual Programming, so that you can
easily modify your programs as your comfort needs change. The
example below demonstrates the Manual Programming method.
6) When setting the program time, note the AM / PM
indicator.
7) With the Auto Recovery feature enabled, you do not
need to set your comfort program times early. Auto
Recovery will determine how early to turn your
system on, so that the room is comfortable at the
program time.

OPERATION
Auto Season Changeover
When the System Selector is in AUTO position, the thermostat
will automatically change between Heating and Cooling systems,
depending on your program. We recommend keeping your
programmed heating and cooling temperatures at least 4°F (2°C)
apart to allow the Auto Season Changeover to occur when the
appropriate temperature span has been reached. However, if
your heating and cooling programs set temperatures are close,
there is a built-in program to prevent the thermostat from
changing unnecessarily.
saving settings. Auto Season Changeover will still function in
Home Today mode, as this is a comfort setting.
For example, you may have the following temperatures
programmed at a given time:
Heat Set Temp = 68°F
Cool Set Temp = 78°F
If the room remperature rises above 78°F, then the thermostat
will automatically change to cool mode and turn on the air
conditioner.
Auto Season Changeover is disabled when the thermostat is in
Temporary or Permanent Override, as these overrides are energy
Likewise, the thermostat will automatically change to heat mode
and turn on heat when the room temperature falls below 68°F.

OPERATION
Auto Recovery
Hunter’s Auto Recovery feature meets the ENERGY STAR® guidelines
for energy efficiency by allowing the heating or cooling system to
recover gradually from an energy-saving setpoint temperature to a
comfort setpoint temperature.
Details of Auto Recovery Operation:
■ Auto Recovery can be disabled by sliding the Recovery switch
on the circuit board to the ALT position. Refer to page 15.
■ Auto Recovery will not operate if Permanent hold, Temporary
Auto Recovery calculates how early to turn your system back On,
so that the room temperature is already comfortable by the start
of the comfort temperature program period. Auto Recovery works
in both Heat and Cool modes.
hold or Home Today is in operation.
■ Auto Recovery can be canceled manually if HOLD/CLEAR is
pressed during the recovery process. If a recovery process is
canceled manually then the recovery process will not start
again until the next program period starts (an exception is
that if time or program is changed then the thermostat will
check Auto Recovery conditions immediately).
For example, in Heat mode, you could have the following
programs:
Program #4 (Overnight)
Set Temp = 60°F
Time = 10pm
Program #1 (Morning)
Set Temp = 68°F
Time = 6am
■ Auto Recovery will be canceled and change to Home
Today mode if HOME TODAY is pressed during the
recovery process.
The room temperature fell to 60°F overnight. Rather than having
the thermostat turning on at 6am, Auto Recovery would note
the temperature difference between 60°F and 68°F and turn the
Heat on approximately 30 minutes early. Therefore, the room
temperature at 6am would be about 68°F instead of 60°F.
■ Auto Recovery will be canceled and change to Temporary
Manual Override mode if the setpoint is adjusted during the
recovery process.
■ If the system changes between heat and cool (automatically
or manually) then the thermostat will recalculate Auto
Recovery again. Setpoint temperature will be changed to the
opposite system’s comfort temperature if the recovery entry
criteria are still met. Otherwise, the recovery process will be
canceled and return to program control mode.
