programmed minimum rotation speed a signal for 0% (corresponding to 0 V output) is
sent.
The calculation is based on a PID algorithm, whose parameters can be customized.

5.7 Collector overheating protection
If the collector temperature exceed this maximum value (default factory setting is 130°C),
it is assumed that steam is already in the system, and therefore no circulation takes
place any more. The collector pump is turned off in this case until the temperature
dropped to a lower value (default factory setting is 110°C).
