Getting Started
Bosch BCC-100 thermostat is designed to work on most
24Vac low voltage heating and cooling systems such as
gas and oil furnaces, heat pumps, and single or
dual-stage systems.
Professional installation recommended for:
▶Separate humidifiers and dehumidifiers
Turn Power Off
Please turn off the unit’s main power at the circuit panel
before beginning the installation process.
POWER OFF WARNING
Failure to turn off power may result in
electrical shock and/or system damage.
Remove the Old Thermostat
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 wires fall back into the wall. Remember, the
power to your HVAC system must be turned off.
1
Note: 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.

Connect the New Wall Plate
Insert all wires vertically from the open socket into the
proper terminal. Ensure that each wire is inserted into the
matching terminal. Use the supplied flathead screwdriver
to fasten each wire. Pull wires gently to ensure wires are
securely fastened.
2
WARNING: Use caution when securing and routing
wires to prevent possible shortage to adjacent terminals.
