■0-10Vinterface[HWS-IFAIP01U-E](option)
To connect the 0-10V interface
TB04 for the 0-10V interface wiring on the Hydro Unit E-BOX
• Communication wiring use 2-core non-polarity wires.
• Use 2-core shield wires to prevent noise trouble.
• In this case, for the system grounding, close (connect) the end of shield wires, and isolate the end of terminal.
• Be sure not input more than DC10V to the analogue input terminals.
• The remote controller line (AB line) is available to connect maximum 2 units.
For example the header plus second remote controller or the KNX or the MODBUS or the Wireless Adapter or
the 0-10V controller.
This option allows Hydro Unit to be controlled either Setting temperatures or Capacity.
Control of Setting tempareture
• DN 680 is set to “1”.
• Set the input method for each setting temperature.
