In addition to sensor B6, sensor B31 at the bottom is used for solar charging control. If
that sensor is not available, sensor B3 at the top is automatically used. If both storage
tank sensors are not available and the solar diagram is active, an error message is
delivered and the collector pump deactivated, irrespective of collector temperature.

Note!
If both storage tank sensors are not available (short-circuit or interruption), the
collector pump is deactivated. If the collector sensor is not available (short-circuit or
interruption), the collector pump is switched off also. In both cases, an error message
is displayed.
