R4 Demand
By means of the flow sensor S1 and the outdoor temperature sensor S2, a mixed
weather-compensated heating circuit can be controlled. Boiler demand via the po-
tential-free relay is triggered depending on the temperature difference between
the set flow temperature and the value measured at the backup heating sensor S3.
