note!
▶ Prevent simultaneous pulsing on both coil windings.
▶ Parallel to the terminals, no other consumers (relay, etc.) may be
connected.
▶ The respective coil connection that does not carry current must be
galvanically isolated (open).
▶ In case two or more valves are connected in parallel, the use of two-
pole or multi-pole switches must ensure that this requirement is met.
