■ The switching point is the system pressure setpoint.
➤ Reset to the delivery condition if the machine is to be regulated by the internal controller
and the program module is still plugged in.

Program module
At the end of the idling period, the compressor switches to STANDSTILL and is in stand-by. The
length of the idling period depends on the control mode being selected.
If the «ON» key is pressed while the remote contact is open, the machine remains in stand-by and
starts as soon as the remote contact closes.
