SOLENOID VALVE WITHOUT LIMIT SWITCH
When the solenoid valves do not have limit switches a two-relay actuator
must be used for each zone (item F430/2), using one relay to manage the
valve and the other relay to manage the pump belonging to the unit.
For each actuator belonging to the same group of zones the pump contacts
must be connected in parallel. No sensor confi guration is required.
