The MM100 blending circuit module is a specialized module for controlling a single mixing circuit in heating systems. It is designed for use with floor thermostats and offers connection options for CW 100 or CW 400. The module enables the control of heating pumps and mixing valves, as well as storage charging pumps and circulation pumps, allowing for flexible adaptation to various heating system configurations. Included in the package is an external flow sensor T0, which can be used, for example, with a hydraulic switch, as well as a sensor for the central heating circuit with mixer TC1. This module is an efficient solution for optimizing heating control and contributes to improving energy efficiency in heating systems.
