Functions associated with the digital inputs
I1 Start/Stop: If input 1 is activated from the control panel (see par. 9
Page 11.0) it will be possible to command the switching on and off of
the pump in remote mode.
I2 Economy: If input 2 is activated from the control panel (see par. 9
Page 5.0) it will be possible to active the set-point reduction function in
remote mode.

With reference to the example in Figure 4, and if the EXT and Economy functions have been activated from
the control panel, the system behaviour will be as follows:
R1 R2

5.5.2 Analogue input 0-10V
The analogue input 0-10V is screen-printed at the base of the 18-pole terminal board:
- A1V (terminal 9): Positive pole
- GND (terminal 10): Negative pole
- A2V (terminal 4): Positive pole
- GND (terminal 5): Negative pole
The function associated with the analogue input A1V is that of regulating the pump rotation speed in
proportion to the input voltage 0-10V itself (see par. 7.1.3 and par. 9 Page 2.0). The input A2V is not
enabled.
