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:
-
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: entwickelt, um operate with boilers that use the Bosch EMS or EMS 2 BUS standard (not OpenTherm). Not geeignet für third-party or very old (pre-2007, iRT) Bosch boilers without EMS.
