Installation & User Manual

RS7210

Before removing the wires from the thermostat or wall
plate, take a photo of all wires for reference, then label
each wire according to the terminal codes.

Disconnect the wires from the old thermostat one by one.
Do not let any wires fall back into the wall. Remember,
the power to your HVAC system must be turned off.

After labeling the wires, we recommend
securing them to an object such
as a pen or clip to prevent them
from falling back into the wall.

Remove the Old Thermostat

1

Please turn off the furnace’s main power at the switchbox
before beginning the installation process.

POWER OFF

Warning: Failure to turn off power
may result in electrical shock and/or
system damage.

Turn Power Off

This thermostat is designed to work on most 24V low voltage
heating and cooling systems such as gas and oil furnaces, heat
pumps, and single-stage systems

Professional installation recommended for:

• Dual fuel systems (heat pump with furnace)

Remove jumper wire if you
have both RC & RH wires

The following are typical wiring diagrams for common systems:

Insert all wires vertically from the open socket into the proper terminal.

Ensure each wire is inserted into the matching terminal (refer to the
photo taken previously if needed). Pull wires gently to ensure wires are

securely fastened.

When all wire connections have been completed, place any surplus
wires back inside the wall.

*For the heat pump system, if the old thermostat has separate wires for
Aux-Heating and Emergency-Heating, twist the wires together and
connect them to the W terminal.

Warning: Use caution when securing and routing wires
to prevent possible short to adjacent terminals.

1) At the thermostat, connect C with the G wire;

2) At the furnace’s wiring terminal, move the G wire to the C terminal,
then use the included jumper wire, G with Y for cooling or G with W for heating.

3) With this configuration the thermostat will have no fan control.
