Function description
The heating circuits are regulated by an FW 500
weather-compensated controller. This always requires
two IPM 2 load switching modules. A 2-wire BUS system
enables communication between the boiler control unit,
the controller and the load switching modules.
The controller is suitable for wall mounting inside the
boiler room or in the living space. Installing it in the living
space enables room temperature hook-up.
