Take a picture of the existing wiring
Make sure that you can clearly read the terminal labels and
see which wires are connected to which terminal from your
photo. You will need to reference this
photo later during the initial setup.
Note:
You can also use the wire labels
we have provided you to correctly
label each wire based on the terminal
where it is connected.

Confirm you have a C-wire connected
to your old thermostat wall plate
If you do not have a C-wire connected to your old
thermostat, please contact a professional or our support
line for further assistance to determine if the BCC50
Thermostat is compatible with your system.

Disconnect the wires from the old thermostat and
remove the wall plate using a screwdriver
Some thermostats will also require you to use a screwdriver to
disconnect the wires. After the wires are disconnected and
the wall plate removed, we recommend wrapping a pen or
pencil around the wires to prevent them from falling back into
the wall.

Note:
If the new Wall Plate
does not cover up any
holes or unpainted spaces
left by your old thermostat,
use this opportunity to
patch any holes and paint.
Pull thermostat wires through the hole in the center
of the BCC50 wall plate and mark the location of
the mounting screws
It is recommended to use the BCC50 Wall Plate as a reference
guide to mark the mounting holes and ensure that
all holes and unpainted
surfaces are covered.
