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.

• If you have a smart phone handy, 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.

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 using a Dual Fuel system, set this switch for GAS. 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.
