Please read this manual for complete instructions on installing and operating your thermostat. If you require further assistance, call Hunter Support at 888- 830-1326 from 8 AM to 5 PM Central Time.

IMPORTANT

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.

ARMCHAIR PROGRAMMING
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.

SYSTEM COMPATIBILITY
Your Thermostat is designed to operate these 24-Volt systems:

Multi-stage heat pumps with auxiliary heat
Single-stage heat pumps
2, 3, or 4 wire gas, oil, and electric furnaces and air conditioning systems
This thermostat will not control 120/240 Volt systems or millivolt systems.

COMPRESSOR PROTECTION
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.

TEMPERATURE RANGE
6Your thermostat can be programmed between 45°F and 95°F (7°C and 35°C). However, it will display room temperatures from 15°F to 99°F (-9°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 15°F (-9°C).

AUTO RECOVERY
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 Options

OPERATION

This system operates on your system’s 24 Volt power supply. The supply is monitored by the thermostat, and it will stop functioning if AC power is lost. (When using backup batteries, “No AC Pwr” will be displayed.) All system controls will remain off until power is restored.

NOTE: The INDIGLO® Night-Light will not function when AC power is lost.

BATTERY WARNING
Fresh alkaline batteries will provide over one year of memory backup and clock operation. However, when the batteries become drained, a low battery warning will appear on the display. When this message occurs, install 2 new AAA batteries. You have approximately 30 seconds when changing the batteries to keep thermostat’s clock and program settings.

NOTE: The default system selection at power-on is HEAT. Batteries are recommended to prevent an undesired system change due to a power outage

Features

What You Need
This thermostat includes two #8 slotted screws and two wall anchors for mounting. To install your thermostat, you should have the following tools and materials.

Slotted Screwdriver(s)
Electric drill and 3/16″ bit
Phillips Screwdriver
Two 1.5 V (AA) size alkaline batteries
Hammer

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. 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.

Wire Labeling

Each wire coming from the wall to the existing thermostat is connected to a terminal point on that thermostat. Each of these terminal points is usually marked with a code letter as shown in Table A on the next page.
The number of wires in your system can be as few as four (for single-stage systems), as many as eight, or any number in between. If you follow the labeling procedures correctly, you do not have to be concerned about how many wires there are.
IMPORTANT! BEFORE DISCONNECTING ANY WIRES, APPLY THE SELF-ADHESIVE LABELS PROVIDED TO THE WIRE AS SHOWN IN TABLE A and B ON PAGES 12-13. (For example, attach the label marked W to the wire that goes to the W or H terminal on your existing thermostat.) IGNORE THE COLOR OF THE WIRES since these do not always comply with the standard.
After labeling wires, disconnect them from the existing thermostat terminals.
Remove existing wallplate. To make sure wires do not fall back into wall opening, you may want to tape them to the wall.
If hole in wall is larger than necessary for wires, seal this hole so that no hot or cold air can enter the back of the thermostat from the wall. This air could cause a false thermostat reading.

Programming Introduction

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%. Your thermostat is capable of holding up to 4 separate programs for each day of the week. You can program weekdays as a group, weekends as a group, all 7 days individually or everyday as a group. The system fan may also be set to run continuously during a program time period. Your Hunter thermostat is pre-programmed to meet the ENERGY STAR® guidelines for energy efficiency.

At power-up or after a reset, all 7 days of the week have these default programs:

		Temperature in F° (C°)
Program Number	Time	Heat	Cool
1	6:00am	68°F (20°C)	78°F (26°C)
2	8:00am	60°F (16°C)	85°F (29°C)
3	4:00pm	68°F (20°C)	78°F (26°C)
4	10:00pm	60°F (16°C)	82°F (28°C)

Refer to the Auto Season changeover feature on page 39 for more information.

Auto Season Changeover
When the System Selection 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 5°F (3°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. Auto Season Changeover is disabled when the thermostat is in Temporary or Permanent Override, or Vacation Hold, as these overrides are energy saving settings. While in any of these modes, “AUTO” will be temporarily removed form the LCD display. “AUTO” will return when these holds are cleared. 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 temperature rises above 78°F, then the thermostat will automatically change to cool mode and turn on the air conditioner. Likewise, the thermostat will automatically change to heat mode and turn on heat when the room temperature falls below 68°F..

Home Today
This Hunter patented feature allows you to quickly and temporarily override your energy saving program setting on days when you are normally away from home with one key press.

Press to enter the Home Today override. The highest program temperature for today will be selected from your programs in Heat mode and become the set temperature. (In Cool mode, Home Today will select the lowest program temperature for today to be the set temperature.)
“HOME” will alternate on the display with the day and any other messages.
When pressed during the first or second program of the day, Home Today will automatically return to program control at the start of the fourth program of the day. If Home Today is pressed after the start of the third program time of the day, the thermostat will remain in Home Today mode until the first program of the next day.
If Home Today is already active, you may similarly extend it to the first program of the next day by pressing the key again after the start time of the third program.
If the system is changed between Heat and Cool modes (either manually or by Auto Season Changeover) during the “Home Today” override period, the setpoint temperature will be automatically updated. It will automatically change from the highest heat program setpoint to the lowest cool program setpoint, or from the lowest cool program setpoint to the highest heat program setpoint.
Press to exit Home Today mode before the schedule ending time. “HOME” is no longer displayed on the LCD screen, and the thermostat returns to the current program.
You can manually change the setpoint temperature while in Home Today mode. Refer to the Temporary Manual Override instructions on page 36. Manually changing the set temperature while in Home Today mode will not affect the
Home Today ending time. However, the set temperature will not change automatically with a manual or Automatic change between heating and cooling
You may also press the Home Today key while in Temporary Manual Override. The operation is the same as the previous point above

Energy Monitor

The Energy monitor feature measures and stores the amount of time the heating and air conditioning system operates. Usage can be displayed for Today (since 12AM), Yesterday, This Month (up to 30 days), Last Month (last 30 days), and Total (up to 999 Hrs. 59 Min.). By monitoring your energy usage, you see how much the setback periods are saving and you can test program adjustment to save even more. Use tables on pages 21-22.

To review energy usage, press to cycle through Today, Yesterday, [number] Days, Last 30 days, and Total. Press again to return to normal mode, or wait 15 seconds for the display to return to normal mode. You can also return to normal mode at any time by pressing RET CLEAR.
For example: This LCD display shows Today’s usage to be 10 Hours, 26 minutes.
Press and hold for 3 seconds to reset the Energy Monitor’s counters while in Energy Monitor mode. The display will blink, and all counters will be cleared to zero

Filter Monitor

Your thermostat also keeps a record of the number of hours your filter has been in use. To maximize your system’s performance and energy efficiency, change or clean your filter regularly.

When the total system run time for heat and cool reaches 500 hours, “FILTER” will alternate on the display with the day to remind you to clean or change your system’s filter. “FILTER” will continue to display until the counter is set back to zero.
Press to review total filter usage. After 15 seconds, the display will return to normal mode, or you can hit RET CLEAR to exit immediately. The Filter Monitor will display up to 999 hours and 59 minutes of usage. In this example, the counter is at 410 Hours, 26 minutes.
To reset the Filter Monitor counter, hold for 3 seconds. The display will blink, and the counter will be reset to zero

SPAN Settings

STAGE 1
Your thermostat is set at the factory to cycle at 1°F (0.5°C) above and below the set temperature in Stage 1. (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. Refer to the Option Menu Stage 1 Span selection on page 17.

Span = 1. This decreases the cycle time by causing your system to run shorter.
Span = 3. This increases the cycle time by causing your system to run longer.

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 the thermostat is powered on or the Reset key is pressed, the Span is reset back to setting 2.

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. 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.

For example, in Heat mode, you could have the following programs:

Program #4 (Overnight) Program #1 (Morning)
Set Temp = 60°F Set Temp = 68°F
Time = 10PM Time = 6AM

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.When the thermostat is in Auto Recovery mode, the display will alternate “RECOVERY” with the day, and the program indicator will flash.

Details of Auto Recovery Operation:

Auto Recovery can be disabled by selecting “NO” in the Option Menu. Refer to page 17.
Auto Recovery will not operate if Permanent hold, Vacation hold Temporary hold or Home Today is in operation.
It will also not operate if the thermostat resets due to AC power loss with no backup batteries.
Auto Recovery can be canceled manually if RET 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).
Auto Recovery will be canceled if HOME TODAY or HOLD is pressed during the recovery process.
The thermostat will enter Home Today, Permanent hold or Vacation hold.
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

Keyboard Lock

The Keyboard can be locked to prevent unauthorized changes to the thermostat.
To lock or unlock the keyboard, press and hold BOTH keys for 3 seconds.
The keyboard is locked when KEY LOCK appears on the display.
All keys are locked, but any time a key is pressed, KEY LOCK will appear on the display for 1 second and the backlight will operate

Backlighting (INDIGLO® Night-Light)
Your thermostat has an electroluminescent lamp that backlights the display for easy viewing in the dark. When any key is pressed the display is illuminated. The display will remain illuminated for 15 seconds after the last key is pressed. This allows the light to stay on if you need to operate several keys. The backlight will decrease in brightness before shutting off.

AC Power Monitor

This thermostat operates on 24V AC, which is provided by your system’s transformer. If the system loses electricity, then the 24V AC power is lost also.
The 2 AAA batteries provide backup operation of the clock, as well as all programs and settings.
If the AC power is lost, then the LCD display will alternate “No AC Pwr” with the day.
Without AC power, the following functions are disabled:
- The system is turned off.
- The Backlight function is disabled.
- The remote sensor temperature readings are not available

Low Battery Warning
Your thermostat has a low battery warning system. When the batteries are detected to be weak, the low battery warning isindicated by “Low Batt” alternating on the LCD display with the day. You then need to replace the batteries with 2 new AAA alkaline batteries. You have 30 seconds to change the batteries before the settings are lost.

Error Mode

If the thermostat is unable to control your system due to an unexpected problem, the thermostat will enter Error Mode. In this condition, the thermostat flashes “Error” and a code number on the LCD display, and shuts off your system. To correct this problem, replace the batteries with 2 new AAA 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
