For wiring of data terminals (4, 5) 2x1 mm2screened (shielded) cable and for control
terminals (16, 17, 18) 3x1 mm2normal cable can be used. Valve potentiometer cable
screen (shield) must be only connected to 4th terminal of controller (Figure 5). Valve
potentiometer (actuator) side of the screen must be left unconnected.

Information
Data terminals (4, 5): Used to transfer valve openness percentage data from valve
potentiometer to controller. Must be used screened (shielded) cable for wiring of data
terminals.
Control Terminals (16, 17, 20): Used to open or close the valve.
