How it works

1The VALV01 is supplied through the contact that calls for the pump (level relay, pressure switch or float switch).
2When energised, after 500 ms, it closes output 1 (15-16) until the supply is cut.
3On the next power-up it closes output 2 (15-18): the pumps alternate.
4With no supply, both outputs are open.
