Parameters of MASTER and SLAVE modulation PCBs
All values of the parameters of the CPU-SMART PCB are shown for all AH unit models.
•
(1)
parameters that could be modified with "001” Password via remote LCD control (even with modbus address ≠ 0).
•
(2) parameters that could be modified with a second level Password which can be requested to the manufacturer's Service
Centre (even with modbus ≠ 0 address).
•
(3) parameters that could be modified only with a Smart Web or via modbus.
