Contact thermostat Electrical connections
Check the node numbers if the circuit boards are
the same design
If multiple circuit boards of the same design (e.g.: two
[EM-C]) are connected to one another via CAN-bus,
those circuit boards must have different and
consecutive node numbers. In this way they are
recognized in CAN-bus and can be configured.
Therefore, compare the node numbers of the
individual circuit boards of the same design and
set them as needed using the node switch.
6.3 Contact thermostat
Contact thermostat as overheating protection
An additional contact thermostat (ready wired) is
available for protection of the underfloor and wall
heating. It switches off the pump in order to protect the
consumer from feed temperatures that are too high.

The contact thermostat is inserted between the
circuit board terminal and the pump.

Contact thermostat as frost protection
If the secondary side is filled with frost protection
because it is designed as an outdoor heat-
ing system, for example (heating of paths, drives...), a
contact thermostat must be installed for the primary
side in order to prevent the heat exchanger from
freezing. This is mounted on the primary circuit return
and clamped electrically so that the secondary pump
switches off as soon as the temperature set on the
contact thermostat is exceeded (e.g.: 10 °C).
