S1
Hydro unit type selection. It is recommended not to change the default value
ON 1 2 3 4
unless you are sure about the Hydro unit type you own.
Normal operation: At device start-up, both LEDs are on during 5 seconds.
L1 (green)
Afterwards only the green LED remains flashing (1900ms Off/100ms On). For
L2 (red)
any other indication, consult the User Manual.
