Solar system and after-heating with 1 store,
3 (optionally 4) sensors and 2 pumps (for solar
heating and after-heating) as well as an optional
0-10 V control of the boiler. The sensor VFD/TRF
can optionally be used for heat quantity meas-
urement. Sensor S1 is used as the flow sensor
SVL.

Solar system and store charge in layers with
1 store, 3 sensors, 1 solar pump and 1 3-way-
valve for store charge in layers. The sensors S4/
TFL and VFD/TRF can optionally be used for heat
quantity measurement. In systems without a
VFD sensor, heat quantity measurement can be
carried out using the sensors S4/TRF and S1/TFL.
