The group fuse is selected such that all relevant requirements for the
electrical installation are met; see technical data. The size of the fuse is set
in the installation flow on the touchscreen. The product adjusts the electrical
power according to this. Once a current sensor has been installed, the built-
in load switch is able to regulate the electric heater's electrical output based
on the set main fuse.
Omnipolar switch
The installation should be preceded by an omnipolar switch according to
overvoltage category III, which ensures disconnection from all electric power
sources.

thermostat may have been triggered. It can be reset by pressing the button
on the electrical switchboard behind the front panel. Always check on
installation that the max thermostat has not tripped.

free input: current transformer, outdoor sensor, room sensor, primary flow
sensor, return sensor, NR/SO, communication to heat pump.
