Operation with pressure switches
If you decide to operate the booster set with pressure switches, they must be connected on the delivery of the booster set. The
pressure switches to be used are B and C and they are connected as indicated in the next paragraph.
8.8
Connection of pressure switches
The pressure switches must be connected to the contacts B and C of the terminal board shown in Figure 47.
8.9
Connecting the low-pressure pressure switch
To comply with the KIWA standard it is necessary to connect a low-pressure pressure switch on the pump intake, set at such a pressure
that it intervenes in the event of water lack.
The pressure switch must be connected to contact N of the Ebox and the contact must open if the pressure falls below the minimum
value. If the KIWA low pressure alarm trips, the set stops and it can be reset only manually, as required by the KIWA standard.

Setting with the display, wizard

"mode" to accept the parameter displayed and move on to the next,
•
"mode" held down for more than 1 second to return to choose the parameter,
