Selector Switches
In order for this thermostat to control your system, the system type must be specified by the selector switches on the printed circuit board inside the thermostat. There is also a selector switch for your choice of Fahrenheit or Celsius temperature display.
■Heating System Selector (HG - HE switch)
The factory position for this switch is in the “HG” position. Leave it in this position if you have a gas furnace or an oil burner. If you have an electric furnace, test to see whether the Heat and Fan come on as expected after installation. If the Fan operation is normal, leave it in the “HG” position. If the Fan does not come on within a minute of the thermostat calling for heat, change the switch position to “HE”. The system selector has no effect in the cooling mode.
NOTE: “HG” position is for gas and most other systems. “HE” position is for certain electric systems having a fan relay.
■F° / C° selector (Fahrenheit / Celsius)
Your thermostat is set for F° mode from the factory. In order to change to C° mode, slide the switch to C° and press the reset button on front of the thermostat with a paper clip.
NOTE: Unless the reset button is pressed, the thermostat will not change temperature mode.

Revising Programs
■Familiarize yourself with manually changing programs, so that you can easily modify the programs as your comfort needs change. Follow the steps below to change the program times and temperatures.
NOTE: 1) The program time can be set in 10-minute increments.
2)The program temperature can be set in increments of 1°F (1°C).
3)After 15 seconds without a key press, the thermostat will return to normal display mode.
4)When setting the program time, note the AM / PM indicator.

Reviewing Programs
To review your program settings, press PROGRAM repeatedly to cycle through the
programs. You can also make changes at any time.
System Selector Switch
The System Selector switch on the front of the thermostat determines the operating mode of the thermostat. You may select COOL, OFF, HEAT.
NOTE: Anytime you install or remove the thermostat from | |
the wallplate, slide the System Selector to the OFF position | |
to prevent the possibility of a rapid system On-Off. | HEAT OFF COOL |
Fan Switch
The Fan switch should normally be located in the AUTO position. The Fan will be turned on along with normal operation of your system. In a normal gas or oil furnace, the Fan will be turned on by your furnace after its warm-up delay. For electric heat, air conditioning, and heat pump operation, the Fan will turn on with the system.
To run the Fan on continuously, slide the Fan switch to the ON position.
FAN ON AUTO
Temporary Manual Override
To temporarily change the current set temperature without affecting your program:
SPAN Setting Mode
Your thermostat is set at the factory to cycle at 1°F (0.5°C) above and below the set temperature. (Span = 2) This setting has been designed to provide a comfortable room temperature under most all conditions. However, if you find your system cycling too fast or too slow, then the Span can be adjusted to modify the cycle time.
■Press and hold BOTH for three seconds.
The display will flash, and SPAN will be displayed on the LCD.
■ Press to raise the Span to 3. This setting INCREASES the cycle time by allowing your system to run LONGER.
■Press to lower the Span to 1. This setting DECREASES the cycle time by causing your system to run SHORTER.
The Span settings remain the same for both HEAT and COOL.
The Span can be changed at any time, and is independent of program times or temperatures.
When batteries are installed in the thermostat, or the Reset key is pressed, the Span is reset back to setting 2.
Low Battery Warning
Your thermostat has a two-stage low battery warning | T | |
system. When the batteries are first detected to be weak, | | |
the first stage low battery warning is indicated by battery | PM | |
symbol flashing on the LCD display. At your earliest | 3 | |
convenience, you need to replace the batteries with 2 new | |
HEAT | TEMP |
AA alkaline batteries. | | |
| |
When the batteries become too weak for normal | | | |
operation, the thermostat enters the second stage low | | | |
battery warning which shuts down the thermostat. In this | | | |
condition, “BATT” flashes alone on the display, and the | | | |
thermostat will turn your system Off. Your system will | | | |
remain shut-off until the batteries are replaced. | | | |
| | |
Note: The thermostat will still keep the current time and your programs in memory until new batteries are installed. After confirming that new batteries have been inserted, the thermostat will return to normal operation.
Error Mode
If the thermostat is unable to control your system due to
an unexpected battery problem, the thermostat will enter
Error Mode. In this condition, the thermostat flashes “Err” on the LCD display, and shuts off your system.
To correct this problem, replace the batteries with 2 new AA alkaline batteries, even if you have recently replaced
them. Next, use a paper clip to press the RESET button next to the keypad. You will need to reprogram your thermostat and confirm normal operation.
If Error Mode returns, please call Hunter Technical support at 1-901-745-9222 for further information.
Auto Cut Off
Your thermostat will automatically cut-off in Heat mode if the room temperature rises above 95°F (35°C). It will cut-off in Cool mode if the room temperature drops below 45°F (7°C). Note that if your system has malfunctioned and no longer responds to thermostat controls, the Auto Cut-Off will have no effect.
