When a single phase brine pump is connected, protect
the heat pump and the DHC only via one common RCD.
If no electric emergency/booster heater is connected, N
must be tapped from X25 for the brine pump.
After connecting all electrical cables, refit and seal the cover over
the mains terminal strip.
