Shared network solenoid
If using solenoid valves, on Master controllers only the solenoid output (DOA) can be configured as a
network solenoid output. The function is useful for multiplexed showcases: the network solenoid valve is
only connected to the Master controller, which opens when at least one of the Slaves is in cooling request.

If configured as the network solenoid, the valve is:
l
open: if at least one of the controllers requires cooling;
l
closed: if there is no control request or if at least one of the controllers has a serious valve alarm (low
superheat, low suction temperature, high evaporation pressure), when suitably configured. See
parameters P10 and PM5.
