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 pump is switched on 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 heat quantity
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.

Method of regulating
the flow:
1. Set the mode switch
in position ON
2. Regulate resp. check
the flow by means of the
flowmeter
3. Adjust the value in
