Figure 4-5 - Hydraulic diagram with DHW production plus semi-rapid puffer tank plus solar (optional)
LEGEND of Figure 4-5:
1 - Heat pump
2 - Filter
3 - Pressure safety valve
4 - Pressure meter gauge
5 - Water inlet
6 - Puffer tank
7 - Domestic hot water outlet
8 - Diverter valve
10 - System filling water inlet
11 - Non-return valve
12 - Heating / cooling supply manifold

14 - “Tw” DHW temperature sensor
Except for items "1" and "14", all items must be field supplied.
The “Tw” sensor (14), supplied with the appliance, must be positioned on the tank using the extension cable connected
to the “Tw” terminal (Figure 5-10), present in the electrical connection compartment (Figure 3-1). Enable DHW operation
via the system settings: Parameter “08” = 2. (section 7.5).
Connect any integrative electrical resistance (17) to a thermostat (15).
Set the integrative electrical resistance point (17), using the Integrative electric resistance thermostat (15), at 5 ° C lower
than the domestic hot water set point.
