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. Figure 4 Figure 5 Figure 2 G Rc Rh Y/O W/B Y1 x RH Figure 3 Figure 6 ® Wiring Diagrams Selector Switches In order for this thermostat to control your system, the system type must be specified by the 4-wire Heat/Cool System selector switches on the printed circuit board inside the thermostat.

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 and most other systems. “HE” position is for certain electric systems having a fan relay. ¦ System Selector (STANDARD - HEAT PUMP switch) The factory position for this switch is in the STD position. Leave it in this position if you have 5-wire Heat/Cool System System Selector STD– HP 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. Be sure the reversing valve wire is connected to the correct terminal for your heat pump (Y/O) or (W/B). ¦ 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.
