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 BELOW. (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.

Wire Labeling (Continued) ¦ 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 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. Table A 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 nonbattery powered thermostats. Mount Wallplate and Thermostat ¦ Remove the wallplate from your thermostat by pressing the release tab on the bottom of the thermostat. See Figure 2. Y1 W/B Y/O Rh Rc G ¦ 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 (2, 3, or 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. Connect Wires and Mount Thermostat to Wallplate ¦ Match and connect the labeled wires to the appropriate coded terminal screws on the wallplate. (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. ¦ If your system is a single stage heat pump and uses an O or B wire, you must move the System Selector switch inside the thermostat to the Heat Pump position. If you have a normal furnace or electric system, leave the switch in the Standard position. Refer to the System Selector section for more information on this switch. ¦ 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 wallplate. ¦ 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 wallplate. Press the top of the thermostat body to snap it into the wallplate. Refer to Figure 6. (NOTE: Do not force the thermostat onto the wallplate, as the terminal pins may be damaged. If it does not snap properly, the thermostat may not work.) ¦ 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.

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...
