The regulator determines the temperature
difference between the collector sensor S1
and the store sensor S2. As soon as the
difference is higher than or identical to the
adjusted value of the switch-on temperature
difference (DTon), the pump (R1) is
activated, the primary circuit is heated. At
the same time the temperature difference
between S4 and S2 is determinated in
comparison with the second adjusted
temperature difference (DT2on). If this
temperature difference is higher than the
adjusted value, the valve is switched by relay
2 (R2), the store is loaded. By means of the
feed and return flow temperature sensors S4
and S5 and the flow measured by the
flowmeter and adjusted in the menu
Adjusted Values, the quantity of heat is
calculated.
The temperature sensor S3 is an additional
measuring sensor, that e.g. can measure the
temperature of the upper part of the store.

1. Set the mode switch
in position ON
2. Regulate resp. check
