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.
WARNING !!! If you use this scheme,
you must to provide a sanitization system
against the Legionella bacterium.
