Bosch CR 100 – Modulierender Raumtemperaturregler

Purpose & Application

• Type: Modulating room controller, weekly programmable.

• Main use: Controls and regulates one Heizen circuit (with or without mixing valve) and domestic Warmwasser (DHW) production.

• Programming: 6 daily switching points can be set für each day of the week, enabling fine adjustment of temperature to fit daily/lifestyle schedules.

• Zones: Intended für direct or mixed Heizen circuits; includes DHW control and support für solar DHW systems.

• Advanced Temperature Regulation: Uses a built-in room sensor für precise Komfort. Automatically adapts consumption based on the building’s real-time needs due to continuous modulation.

• Weekly programming: Allows für detailed weekly scheduling.

• Energy, Maintenance & Error Feedback: Visualizes energy consumption, signals maintenance intervals, and displays error codes on the backlit LCD.

• Smart Interface & Display:

  • Illuminated (backlit) LCD für easy status reading.

  • Modern, compact design with intuitive operation knob and buttons.

• Communication: Interfaces and configures all connected modules automatically via EMS BUS; compatible with MM100/MS100 modules and can be used with Bosch Heatronic 3®/4® boilers and installations.
