<p>The system comprises at least one solar collector connected to the pump of a fluid circuit. The pump is controlled in relation to the difference in temperature measured by sensors attached to the collector and to the hot water storage tank, each using appropriate modes for the specific purposes. A permanent supervision protects the system from being operated with the sensors installed at the wrong device and initiates an immediate emergency action. The mistake is recognized by a comparison of the obtained value with a saved specific temperature threshold.</p> |
