Option TKV collector flow sensor. This can
be connected as an additional measuring
point and is then used as a reference sensor
for speed control of the solar charging.

Charging plausibility:
If the TKV option collector flow sensor (08-108) and flow sensor (08-107) options are active, the collector flow and
return are registered by temperature sensors.
The temperature difference between these two values is measured. If this difference is 2 on average, charging is
completed because no sensible charging of the consumer can take place any longer.
Also, the difference between collector sensor TKO and collector flow TKV is monitored. An excessive drifting
apart of these values should be avoided.
If the collector maximum temperature on the TKO (08-011) is reached less 20 K, the minimum speed (08-035) is
increased continuously as the temperature rises. In this way, the temperature at the collector should be forced to
be dissipated.
nmin = (08-035), if TKO < TKmax (08-011) - 20 K
nmax = (08-036), if TKO > TKmax (08-011)
