Data type Comment
Bit Read relay status.
Bit Read input status.
A "TRUE" logic level on the inputs are
extended to minimum 5 seconds.
Unsigned Value = 310 → V3.10
Integer
Value =-14400 ... +14400
Signed Integer
→ -14400 ... +14400 l/h

Signed Integer
Signed Integer Value = 1 → 0.01 l
Unsigned TRUE → Sensor error
Integer FALSE → Sensor OK
Unsigned Value = 39 → Device ID = 39
