IMPORTANT INFORMATION

1. This thermostat is designed to work on the following systems:
   Gas –Standing Pilot
   Gas –Electronic Ignition
   Gas –Fired Boilers
   Gas-Millivolt Systems
   Oil-Fred Boilers
   Oil-Fred Furnace
   Electric Furnace
   Electric Air Conditioning
   This thermostat will NOT control single-stage or multi-stage heat pumps or 1101220 V baseboard electric heating systems.
2. Temperature RangeThis thermostat can be programmed between 45T and 95T (TC and 35(). It will display room temperatures from 30T to 99T (O’C and 3TC). “HI” will be displayed if the temperature is higher than 99’F (3TC), and “LO” will be displayed if the temperature is lower than 30’F (CC). This thermostat will automatically cut-off in Heat mode if the temperature rises above 95T (35’C), and automatically cut-off in Cool mode if the temperature drops below 40T (CC).
3. Compressor Protection This thermostat provides a 3.5 minute delay after shutting off the cooling system before it can be restarted. This feature will prevent damage to your compressor caused by rapid cycling. It does not prevent a rapid compressor restart due to short power outages.
4. Battery WarningTwo fresh AA alkaline batteries should provide well over one year of service. However, when the batteries become drained, the Low Battery Indicator will flash on the display. When this message occurs, install new alkaline batteries. You have approximately 1 minute to change the batteries and keep thermostat’s clock and program settings. Once the batteries have become too low to ensure proper operation, your system will be turned Off, and the display will be cleared except for flashing Low Battery Indicator on the LCD display.

FEATURES

ENERGY STAR@ PARTNER

As an ENERGY STARS Partner, Hunter Fan Co. has determined that this programmable thermostat meets the ENERGY STARS guidelines for energy efficiency.

INSTALLATION

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)
• Small Philips screwdriver
• Hammer
• Electric drill and 3/16″ bit
• Two 1.5 V (AA) size alkaline batteries

Remove Old Thermostat

• 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 the wall mounting plate is exposed, look for wires.If wires are not visible, they may be connected to the back of the wall plate. Again, look for screws, tabs, etc. Some models have doors that open to expose wires and mounting screws. See Figure 1.

Typical Home Thermostats

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 below.
• The number of wires in your system can be as few as two (for heat only 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.
• There is often no terminal marking on the existing thermostat of two wire, heat only systems. Just connect either of the wires to the RH terminal, then connect the other wire to the W terminal to complete the circuit.
• IMPORTANT! BEFORE DISCONNECTING ANY WIRES APPLY THE SELF-ADHESIVE LABELS PROVIDED TO THE WIRE AS SHOWN IN TABLEA BELOW. (For example, attach the label marked W to the wire that goes to the W or H terminal on your existing thermo- stat.) IGNORE THE COLOR OF THE WIRES since these do not al- ways comply with the standard.
  

Wire Labeling (Continued)

After labeling wires disconnect them from the existing thermostat terminals. Remove existing wall plate. 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 with insulating material 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.

NOTE: Do not connect a “Common” wire (sometimes labeled “C”) to any terminal on this thermostat. Tape up the wire and do not use. This wire provides electricity to non- battery powered thermostats.

Mount Wall plate and Thermostat

Remove the wall plate from your thermostat by pressing the release tab on the bottom of the thermostat. See Figure 2.

Position wall plate on wall and pull existing Wires through large opening. Then level for appearance. Mark holes for plastic anchors provided, if your existing holes do not line up With those on the Hunter wall plate. Drill holes With 3/16″ bit and gently tap anchors into the holes until flush With wall. Reposition wall plate to wall, pulling Wires through large opening. Insert mounting screws provided into wall anchor and tighten. See Figure 3.

Connect Wires and Mount Thermostat to Wall plate

• Match and connect the labeled wires to the appropriate coded terminal screws on the wall plate. (See figure 4, 5.) Ignore any wires which may be present, but which were not connected to the old thermostat.
• Refer to the Wiring Diagrams below to be sure your system is wired correctly.
• Be sure to tighten the terminal screws securely, otherwise a loose wire could cause operational problems with your system or thermostat.
• Push excess wire back into the hole to prevent interference when installing the thermostat to the wall plate
• Make sure the System Switch is set to OFF, and the Fan Switch is set to AUTO.
• Insert the bottom tab on the thermostat body into the slot at the bottom of the wall plate. Press the top of the thermostat body to snap it into the wall plate. Refer to Figure 6.
• Insert the two AA size alkaline batteries, observing the polarity marked inside the battery compartment.
• Switch on the main power at the panel or furnace.

• When the total system runtime for heat and cool reaches 400 hours, the Filter Change Indicator will flash as a reminder to check your system’s filter.
• Filter: After changing or cleaning the system’s filter, press and hold the Filter Key for 3 seconds. The display will blink, and the timer will be reset to zero.

SPAN Setting Mode

Your thermostat is set at the factory to cycle at IOF (0.50C) 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 system. When the batteries are first detected to be weak, the first stage low battery warning is indicated by battery symbol flashing on the LCD display. At your earliest convenience, you need to replace the batteries with 2 new 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.

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.

• When the thermostat is in Auto Recovery mode, the display will alternate “RECO” with time, and the program indicator will flash.
• Auto Recovery can be disabled by sliding the Recovery switch on the circuit board to disable.
• Auto Recovery will not operate if Permanent hold or Temporary hold is in operation.
• Auto Recovery can be canceled manually if HOLD / RETURN is pressed during the recovery process.
• Auto Recovery will be canceled and change to Temporary Manual Override mode if the setpoint is adjusted during the recovery process.

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 1-888-830-1326 for further information.

Auto Cut Off

Your thermostat will automatically cut-off in Heat mode if the room temperature rises above 950F (350C). It will cut-off in Cool mode if the room temperature drops below 400F (CC). Note that if your system has malfunctioned and no longer responds to thermostat controls, the Auto Cut-Off will have no effect.
