The main controller of the new, expandable WPM system. The WPM supports the control of one direct and two mixed heating circuits. Two heat pumps can be operated in cascade, and additional heat pumps can be connected via the WPM system extension. The WPM offers a 230V fault contact for external detection of system faults. High-efficiency circulation pumps can be connected directly via relay outputs or PWM outputs. The WPM board is located in a drip-proof wall housing, which offers space for additional components such as DIN rail relays, etc. The entire system is operated via the built-in control unit. The well-thought-out cable routing and the large installation space for the electrical installation make the connection simple and error-proof. Three sensors, which can be used either as immersion or contact sensors, as well as an external sensor are included in the scope of delivery. An internet interface and smart home interfaces are optionally available.
