The Bosch/Buderus MS 200 solar module is a functional solar module for preparing hot water and supporting heating with a solar installation. The MS 200 module is used to control actuators (e.g. pumps) in a solar thermal system, a reset system or a loading system. The module is suitable for use with energy-saving pumps. Extended functionality due to support for a large number of typical hydraulic schemes for connecting a solar system with a heating or water supply system. To access all functions, a Buderus RC310 or Bosch CW400 control panel is required.
