Max. 16 valves can be connected to the solenoid valve control. The connections of a
valve are arranged vertically. One terminal is available for the PE connection of a valve.

> or = the pulse time when using software version 2.10 or higher.
The control extends the effective pause time automatically to the above ratio.
