WIRING

Wiring-Conventional System

If labels do not match letters on the thermostat, check the chart below and connect to terminal as shown here (see notes, below).

	If wires will be connected to both R and Rc terminals, remove metal jumper (see page 6).
	Do not use C or X. Wrap bare end of wire with electrical tape.
	If you have a heat pump without auxiliary/backup heat connect O or B, not both. If you do not have a heat pump, do not connect B. Wrap bare end of wire with electrical tape.
	Place a jumper (piece of wire) between Y and W/Aux if you are using a heat pump without auxiliary/backup heat.

Wiring-Heat Pump

Connect wires: Heat Pump

1. Match each labeled wire with same letter on new thermostat.
2. Use a screwdriver to loosen screws, insert wires into hole under screw, then tighten screws until wire is secure.
3. Push any excess wire back into the wall opening.

Alternate wiring (for heat pumps with auxiliary or backup heat only)

If labels do not match letters on the thermostat, check the chart below and connect to terminal as shown here (see notes, below).

	Leave metal jumper in place, connecting R & Rc terminals.
	If your old thermostat had both V and VR wires, stop now and contact a qualified contractor for help.
	If your old thermostat had separate O and B wires, wrap the B wire in electrical tape and do not connect.
	If your old thermostat had Y1, W1 and W2 wires, stop now and contact a qualified contractor for help.
	Do not use C or X wire. Do not use B wire if you already have O wire. Wrap bare end of wire with electrical tape.
	Do not use L wire. Wrap bare end of wire with electrical tape.
	If your old thermostat had E and Aux wires (or alternate wires), connect both wires to Aux terminal.
