INSTALLATION

12

Connect Wires and Mount Thermostat Cover to Wall Plate

■Match and connect the labeled wires to the appro- priate 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 on the back 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 interfer- ence 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.

Selector Switches

13

In order for this Hunter thermostat to control your system, the system type must be specified by selector switches on the printed circuit board inside the thermostat.

NOTE: When changing these features after instal- lation, move the HEAT / COOL selector switch to OFF before removing the thermostat from the wall.

System Selector Switches:■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.

If Fan operation is normal, leave the switch 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 cool- ing mode.

NOTE: “HG” position is for gas and most other systems. “HE” position is for certain electric systems having a fan relay.

■Furnace or Heat Pump selector (STD - HP switch)

The factory position for this switch is in the STD position. Leave it in this position if you have ANY system that uses gas, oil, electric, or hot water heating.

If you have a single-stage Heat Pump (no auxiliary or emergency heat source), then slide the switch to the HP position.

■Auto Recovery selector (DISABLE / ENABLE)

Your thermostat is set from the factory with the Auto Recovery Feature enabled, which complies with the EPA ENERGY STAR® Program. If you prefer to use normal recovery, slide the switch to the ALT position.

Refer to page 32 for a complete discussion of the Auto Recovery feature.
