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.
