IMPORTANT
1Read 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
2All installation is normally performed at your thermostat.
ARMCHAIR PROGRAMMING
3You 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.
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.
OPERATION
4Your 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
5The 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 provide a delay when there are power outages.
TEMPERATURE RANGE
6Your thermostat can be programmed between 40°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 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.
Read This Before Installing Thermostat (continued)
POWER FAILURE
7Whenever the main power is interrupted or fails, the battery power retains the programs and current time.
AUTO RECOVERY
8Your 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 Selector Switches information on pages 14-15.
BATTERY WARNING
9Fresh alkaline batteries should provide over one year of service. However, when the batteries become drained,
“BATT” will alternate on the display with the current time. When this message occurs, install 2 new AA 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 “BATT” flashing on the LCD display.
!
CAUTION: Once the “BATT” only display occurs, the thermostat is shut down, and your system will no longer operate. In this condition, there is no temperature control of your dwelling.
NOTE: The INDIGLO® night-light will not function when the thermostat is in low battery condition.
NOTE: If you plan to be away from the premises over 30 days, we recommend that you replace the old batteries with new alkaline batteries prior to leaving.

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. (See Figure 1).

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 this page.
■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 TABLE A ON THIS PAGE. (For example, attach the
label marked W to the wire which goes to the W or H terminal on your existing thermostat.) IGNORE THE
COLOR OF THE WIRES since these do |

Y |
not always comply with the standard. |

Mount Wallplate and Thermostat
■Remove the wallplate from your thermostat by pressing the release tab on the bottom of the thermostat. (See Figure 2.)
■Position wallplate 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 wallplate.
■Drill holes with 3/16” bit and gently tap anchors into the holes until flush with wall.
■Reposition wallplate to wall, pulling wires through large opening. Insert mounting screws provided into wall anchor and tighten. (See Figure 3.)

NOTE: 5-wire Systems
If your thermostat has one wire marked R or RH (4-wire system), then leave the jumper wire between the RH and RC terminals on the wallplate.
Otherwise, if you have separate RH and RC wires (5-wire system), then remove the jumper wire between the RH and RC terminals.
