
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.
