Heat pump water heater - TECHNICAL INFORMATION FOR INSTALLERS
Use this configuration whenever users do not have a two-tier electricity rate.
Fig. 9
The water heater will always be connected to the power supply network to ensure 24h operation.
If you have a dual electrical power supply and a suitable meter, during the hours when the product is
Fig. 10 not powered protection from corrosion via impressed current anode is ensured by rechargeable
batteries that must be inserted as they are not supplied with the product. (see figure 1)
ELECTRICAL CONNECTION WITH DUALPOWER SUPPLY AND HC-HP SIGNAL
Offers the same cost advantages compared to the two-tier rate configuration but, additionally, it allows
for obtaining rapid heating thanks to the BOOST mode that activates heating even with the HP rate.
1) Connect a bipolar cable to the appropriate signal contacts on the meter.
Fig. 11
2) Connect the signal bipolar cable (B) to the special EDF connector "SIG1" inside the electrical box to
the right of the product (pierce the rubber pads to obtain a section suitable for its passage).
WARNING: The EDF signal has a voltage of 230V.
3) Enable the HC-HP function with the P7 parameter on the installer's menu. (See paragraph 7.7).
• If you have an FV system to be connected or an available SG signal, you can connect a bipolar
cable from the inverter or the SG signal cable (one in alternative to the other) to the electrical box on
the right hand side of the product (secure the cable into the dedicated cabling sheath). Connect said
cable (C) to the "SIG2" connector and enable the PV (P9) or SG (P18) function on the installer's
menu (see paragraph 7.7). Caution: 230 V signal.
Fig. 12
• Only for SYS models, if you have an auxiliary heat generator (boiler) and you want to replace the
integration performed by the heating element with it, you can connect a bipolar cable (D) from the
heat generator (if enabled) to the electrical box on the right hand side of the product (secure the
cable into the dedicated cabling sheath). Connect the cable to the "AUX" connector and set the P8
parameter on 3 via the installer's menu (see paragraph 7.7).
In the event of connection of the SYS version to the boiler/stove, it is advisable to use upper sensor slot
S3.
Fig. 15
In the event of connection of the SYS versions to the solar control unit (lower heat exchanger), the
lower sensor slot on its own (S2) or both sensor slots (S2) and (S3) may be used.
5. INITIAL START-UP
Once the appliance is connected to the hydraulic and electric systems, the water heater must be filled with water from
the domestic water supply network. In order to fill the water heater, it is necessary to open the central tap of the
domestic network supply and the nearest hot water tap, while making sure that all the air in the tank is gradually
expelled.
The product is not supplied with batteries.
In the event of installation with batteries, use 4 type NiMh, AA, 1.2V, 2100 mAh minimum, rechargeable
batteries with a minimum of 1000 recharging cycles and a minimum operating temperature of 55°C (use
batteries supplied from the manufacturer's catalogue). These should be inserted carefully observing the
correct polarity, in the special seat inside the front casing that is accessible by removing only the external
frame (fig. 1). These will ensure correct operation of the impressed current anode also during any electrical
power cuts. The appliance will automatically recharge them.
