  • Page 3: About These Instructions

    Operation and functions The WPM heat pump manager is supplied in two versions. The first is the WPMS control cabinet model and the second the WPMW in a wall-mounted housing. At the point of installation a BUS line is laid between the heating heat pumps and the WPM to establish communication between the two.
