2-store-solar system with valve logic with
2 stores, 3 sensors, 1 solar pump and 1 3-way-
valve. The sensors S4/TFL and VFD/TRF can op-
tionally be used for heat quantity measurement.
In systems without a VFD sensor, heat quantity
measurement can be carried out using the sen-
sors S4/TRF and S1/TFL.
