3. D.H.W. setting (basic setting 65˚C). Only with sensor.
Operation is as follows:
Imagine: the setpoint for D.H.W. temperature has been
preset at 65°C, the D.H.W. cut-in temperature differen-
tial at 5°C, and the maximum flow temperature during
D.H.W. operation at 80°C (factory settings).
The appliance will modulate at the preset maximum flow
temperature during D.H.W. operation, and will shut down
at a D.H.W. temperature of 70°C (preset value +5°C).
The appliance will cut back in at a D.H.W. temperature
of 65°C (preset D.H.W. temperature
+5°C - D.H.W. cut-in temperature differential).
Both the D.H.W. cut-in differential and the maximum flow
temperature during D.H.W. operation can only be set via
the service menu (para. 10.3.9 and 10.3.10).
