Note
For every appliance fault, output X2.10 issues a 230V
signal.
In the case of temporary faults, the output switches the
signal through for a specific time.
In the case of faults that result in a permanent appliance
shutdown, the output switches through permanently.

priate terminals in the heat pump manager.
The ISG is not supplied with power by the heat pump.
