Purpose & Application

  • Type: Modulating room controller, weekly programmable.

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

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

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

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

  • Weekly programming: Allows for 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 for 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.

  • Compatibility: Designed to operate with boilers that use the Bosch EMS or EMS 2 BUS standard (not OpenTherm). Not suitable for third-party or very old (pre-2007, iRT) Bosch boilers without EMS.
