The main circuit board on the appliance is fitted with an earth contact

for operating purposes only, not for safety purposes.

Open the cover to access the connection board located on the right,

rear side of the product and carry out the connections according to

the chosen configuration:

PERMANENT ELECTRICAL CONNECTION (24h/24h)

Use this configuration whenever users do not have a two-tier elec-

tricity rate. The water heater will always be connected to the power

supply network to ensure 24h operation.

ELECTRICAL CONNECTION WITH DUAL POWER SUPPLY AND

HC-HP SIGNAL (power supply 24h/24h)

It offers the same cost advantages as the two-tier rate configuration

but, additionally, it provides rapid heating thanks to the BOOST mode

that activates the heating even with the HP rate.

1) Connect a bipolar cable to the appropriate signal contacts on the

meter.

2) Connect the signal bipolar cable (B) to the appropriate EDF con-

nector "SG1" which is inside the connection box (make a hole in

the rubber plugs to create a suitable passage section).

WARNING: The EDF signal has a 230V voltage.

3) Activate the HC-HP function through the P1 parameter in the in-

staller menu.

AUXILIARY CONNECTION

If you have a PV system to be connected or an SG signal available,

you can connect a bipolar cable from the inverter or the SG signal

cable (alternatively, not both) to the connection box (secure the cable

into the dedicated cabling sheath).

Connect this cable (C) to the connector called "SG2" and activate the

PV (P11) or SG (P13) function via the installer menu.

WARNING: signal 230 V.

Only for SYS or TWIN SYS models, if you have an auxiliary heat gen-

erator (e.g. boiler) and you would like to use it instead of the integra-

tion carried out by the heating element, you can connect a bipolar

cable (D) from the heat generator (if provided) to the product connec-

tion box (secure the cable into the dedicated cabling sheath).

Connect the cable to the connector called "AUX" and set the P14

parameter to 1 via the installer menu.

If you connect the SYS version to the boiler/stove, it is advisable to

use upper sensor slot S3.

If you connect the TWIN SYS version to the boiler/stove, it is advis-

able to use sensor slot S4 for the lower heat exchanger and S3 for

the upper one).

If you connect the SYS or TWIN SYS versions to the solar control unit

(lower heat exchanger), you can use the lower sensor slot on its own

(S2) or both sensor slots (S2) and (S3/S4).
