5.1.1)
The HP should maximize the use of energy when there is a PV production. For that, “Suel” should be
defined according needs, and in both situations (On / Off), the “Syst” message appears in display
blinking and operation is:
-
the achievement of the “Tma” while PV is available (default is 50ºC, but can be defined between 50ºC –
70ºC);
-
the achievement of “Tmin” to ensure a minimum temperature at the tank when PV is not available (default
is 45ºC but can be defined between 15ºC – 70ºC).
