Fine-wire fuse
M 6.3 A to protect the control PCB.

In summer mode, the circulation pump operates for approx. 10
seconds after a maximum idle period of 24 hours. Then, the
cylinder primary pump and the DHW circulation pump (if installed)
will run for 20 seconds. This prevents the pump from seizing up.
The burner will be switched OFF for approx. two minutes if it is
operating when the anti-seizing pump protection is enabled.
