3.8.1 Remote information board
The contact can be changed to NO or NC by wiring according to the following diagrams (e.g. wiring on 30 & 31 = NO
contact).
3.8.2 RS485 – Hardware connection
RS485 connection must be plugged on the J2 connector:
• Terminal 1: Data -
• Terminal 2: Data +
• Terminal 3: GND
The SW1 switch is used to turn line resistance on or off. Depending on your
needs, these resistances can be activated or deactivated (see diagram).
X22 Connector (36-37-38): Remote
steam production dry contact.
X21 Connector (33-34-35): Remote
general fault dry contact.
X20 Connector (30-31-32): Remote tank
