Separate heat exchangers for heating circuit and d.h.w. heating; instantaneous d.h.w.
heating via storage tank connected to a separate heat exchanger; d.h.w. charging via
charging pump. Temperature sensor B71 can be used as follows:
•
As a d.h.w. temperature sensor, or
•
For maximum limitation of the temperature differential; in that case, the d.h.w. tem-
perature must be acquired with thermostat F1
