Remove Old Thermostat
Remove old thermostat but leave wallplate with wires attached.
Identify Wires
If any wires are not attached to your old thermostat or are attached to a
terminal marked C or C1, they will not be connected to your new thermostat.
Wrap the bare metal end of each of these wires with electrical tape, so it
cannot touch and short other wires.
Warning
Disconnect wires and remove the old wallplate only after all wires are
labeled. Wrap the wires around a pencil to prevent them from falling through
the wall opening.
Mount New Wallplate
- Loosen the locking screw at the bottom of the thermostat. Note that the screw is captive and cannot be removed from the wallplate.
- Separate the thermostat from the wallplate as per Figure 1.
- Position the wallplate against the wall and mark hole positions with a pencil. NOTE: Levelling is for esthetics only and will not affect the performance of the thermostat.
- Drill holes at the marked positions and insert supplied wall anchors.
- Pass the wires through the large opening located at the bottom center of the wallplate as per Figure 2.
- Secure the wall plate to the wall with supplied mounting screws as per Figure 3.
- Connect the wires to the terminals.
Connect Wires: Conventional Systems (typical wiring)
- Match each labeled wire with the terminal having the same letter.
- Loosen the terminal screws using a screwdriver, insert the wires, then tighten the screws.
- Push any excess wire back into the wall opening.
Connect Wires: Conventional Systems (alternate wiring)
- REMOVE THE JUMPER BETWEEN R AND RC IF YOU HAVE WIRES ON BOTH R AND RC.
- DO NOT USE C, C1, OR X WIRE. DO NOT USE B WIRE IF YOU ALREADY HAVE 0 WIRE. 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.
Connect Wires: Heat Pump Systems with Auxiliary/Backup Heat (typical wiring)
- Match each labeled wire with the terminal having the same letter.
- Loosen the terminal screws using a screwdriver, insert the wires, then tighten the screws.
- Push any excess wire back into the wall opening.
Connect Wires: Heat Pump Systems with Auxiliary/Backup Heat (alternate
wiring)
- LEAVE JUMPER IN PLACE, CONNECTING R AND RC.
- THIS THERMOSTAT CAN NOT BE USED IF YOUR OLD THERMOSTAT HAD ANY TWO OF THE FOLLOWING WIRES R, RC, V, OR VR.
- 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 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.
- IF YOUR OLD THERMOSTAT HAD E AND AUX WIRES (OR ALTERNATE WIRES), CONNECT BOTH WIRES TO AUX TERMINAL.
Set Heating Fan Control
Set jumper JP1, on the back of the thermostat, if you have connected a wire
to the G terminal.
HG Leave the jumper in this factory-set position if you have a gas or
oil furnace.
HE Place the jumper to this position if you have an electric furnace.
Incorrect jumper setting: An incorrect setting is noticeable in a gas or oil heating system. When heating starts, you will initially feel cold air coming out of the vents as the fan is running before the furnace has enough time to heat up the air.
Set Heat Pump Reversing Valve
Set jumper JP2, on the back of the thermostat, if you have a heat pump
.
- Leave the jumper in this factory-set position if you have connected O wire to the O/B terminal.
- Place the jumper to this position if you have connected B wire to the O/B terminal.
Incorrect jumper setting: The heat pump operation will be reversed, i.e., it will cool in Heat mode and will heat in Cool mode.
Install Batteries and Thermostat
- Install 2 AAA batteries on the back of the thermostat.
- Align the two brackets on the top of the thermostat with the corresponding slots on the top of the wallplate.
- Push the thermostat against the wallplate.
- Tighten the screw at the bottom of the thermostat.
- Turn power back on at the heating/cooling system.
