For conventional (gas/oil/electric) Heat Only Cool Only
For heat-pump systems Up To 4-Heat & 2-Cool

C-wire or (24Vac) is required to power the thermostat.

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.

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.

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

WARNING: Use caution when securing and routing wires to prevent possible shortage to adjacent terminals.
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.

Jump Wire



The following are wiring diagrams for common systems:

  • Conventional Heating (2 Stages) / Cooling System (2 Stages) with humidifier
    Install a jumper between R/h and Rc only if a single transformer is used for heating and cooling. Otherwise, connect the heating transformer to R/h and/or the cooling transformer to Rc.
  • Conventional Heating /Cooling System with C wire
  • Conventional Heating /Cooling system without the C or spare wire (also commonly called a 4-wire system)
    • At the unit, connect C with the G wire
    • Connect Y to G
  • Heat Pump 4 Heat/ 2 Cool with Dehumidifier

    Connect Rc to R/h
  • Heat Pump 3 Heat / 2 Cool
    • Connect Rc to R/h
    • Connect W to W2 to operate both stages of electric heat at the same time
  • Heat Pump 2 Heat /1 Cool

    Connect Rc to R/h

Mount the New Wall Plate


Use the enclosed screws and anchors to mount the new wall plate. In most cases, you can utilize the same mounting position of your old thermostat. Be sure to check the alignment of your wall plate before installation.

Attach Bosch BCC-100 to the Wall

  1. First, align the two clips on the back of the Bosch BCC-100 into the corresponding slots on the top of the wall plate.
  2. Firmly press forward until you hear a click to secure the thermostat into position.
    Bosch-BCC100-Thermostat-Fig.11Ensure the C-wire (if used) is properly connected to the heating and cooling equipment and thermostat. Switch the power back on for the heating/cooling system at the main switch box.
