2.45 P Δp-off DW • After-sales service password is required
Setting of the differential for pump switch-off in potable
water operation. The set pressure for switching off the pump
(menu 2.13) in rainwater operation together with the differ-
ential set here must be at least 0.5 bar greater than the set
pressure for switching on the pump (menu 2.12).
(For pump switch-off set pressure in rainwater operation, see
menu 2.13)

2.50 choice-stop • Password 02 is required
Display of switch-off logic adapted as appropriate to the
pump. F1 = 4 means switch-off pressure of 4 bar for the MC
304 pump.

2.53 p off var. • Password 02 is required
Display of the variable pressure for pump switch-off.
The value is calculated as follows:
