ATTENTION: incorrect wiring of the sensor can damage the appliance and the sensor.

NOTE: the choice of sensor limits the maximum set-point that can be reached.

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.

The pressure switches must be connected to the contacts B and C of the terminal board shown in Figure 47.

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 E.Box 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.

The E.box D can be configured with a simple wizard. The device asks the user for all the parameters necessary for its configuration. If necessary,

it can be loaded by pressing the "set" + "+" keys when switching on. To navigate in the wizard, use the following keys:

"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,

"-" e "+" to vary the value of the parameter.
