All these parameters are adjusted via the Wizard
The 4 to 20 mA pressure transducer is connected to AI 2, to the 4 (-) and 12 (+)
terminals
A through-connection must be made between 5 and 7.
Make sure that dipswitch AI 2 is in the Current signal position (down).
At the first and last connected regulators, make sure that the RS-485 bus termination
dipswitches are set to ON: all others should be set to OFF
Location and selection AI 2 dip switch and RS-485 bus termination
PID control is started by connecting 8 (DI 1) to 6 (+24 V).
Flushing is activated by connecting 9 (DI 2) to 6 (+24 V).
To switch from target value 1 to 2, connect 10 (DI 3) with
6 (+24 V).
A fault can be reset remotely by connecting 14 (DI 4) with 12 (+24 V).
Water thermostat (°C) or float must be connected to 16 (DI 6) and
12 (+24 V).
Connect A and B (RS-485) of the various regulators with each other.
