Installation Instructions

Remove and Replace the Old Thermostat

To install the thermostat properly, please follow these step-by-step instructions. If you are unsure about any of these steps, call a qualified technician for assistance.

• Assemble tools: Flat-blade screwdriver, wire cutters, and wire strippers.
• Make sure your Heater/Air Conditioner is working properly before beginning installation of the thermostat.
• Carefully unpack the thermostat. Save the screws, any brackets, and instructions.
• Turn off the power to the Heating/Air Conditioning system at the main fuse panel. Most residential systems have a separate breaker for disconnecting power to the furnace.
• Remove the cover of the old thermostat. If it does not come off easily, check for screws.
• Loosen the screws holding the thermostat base or subbase to the wall and lift away.
• Use a smartphone or mobile device to take a photo of the wiring for future reference.
• Disconnect the wires from the old thermostat. Tape the ends of the wires as you disconnect them, and mark them with the letter of the terminal for easy reconnection to the new thermostat.
• Keep the old thermostat for reference purposes until your new thermostat is functioning properly.

Wire Connections

If the terminal designations on your old thermostat do not match those on the new thermostat, refer to the chart below or the wiring diagrams that follow.

* O/B is used if your system is a Heat Pump.

The Thermostat Backplate

To remove the thermostat backplate: Gently separate the display from the base by pulling first from one side, then the other until the two pieces unsnap.

IMPORTANT: This thermostat requires both R (24 VAC Return) and C (24 VAC Common) be connected to the backplate terminals.

Check Dip Switches

Ensure which switch is correct for your system. Dip switches are located on the back of the thermostat.

1. When GAS/EL or HP is set for GAS/EL: This switch (GAS or ELEC) controls how the thermostat will control the Fan (G) terminal in heating mode. When GAS is chosen, the thermostat will not energize the Fan (G) terminal in heating. When ELEC is chosen, the thermostat will energize the fan in heating.
2. When GAS/EL or HP is set for HP: This switch (GAS or ELEC) defines the Aux Heat type. When GAS is chosen, the auxiliary heat will not be allowed to run during heat pump operation. When ELEC is chosen, up to two stages of auxiliary strip heat will be allowed to run.

For Heat Pump Only

When the GAS/EL or HP dip switch is configured for HP, this dip switch (O or B) must be set to control the appropriate reversing valve. If O is chosen, the W1/O/B terminal will energize in cooling. If B is chosen, the W1/O/B terminal will energize in heating.

This dip switch configures the thermostat to control a conventional gas/electric system or a heat pump. If your system is anything other than a heat pump, leave this switch set for GAS/EL.
