System diagrams Operational safety for the controller/system is only 1 collector, 1 storage tank guaranteed if these are used for the intended purpose and if no wiring errors have been made. Failure to follow the connection diagrams and safety instruc- tions can endanger the pump/ system and human life. -
Page 10: Controller Functions
Controller functions 7.1 General controller functions The controller compares the temperatures of the various measuring points and charges the storage tank optimally. If the collector temperature exceeds the storage tank temperature, the solar circuit pump is switched on. Monitoring and protective functions ensure safe system operation. -

Page 13: Protective Functions
7.2 Protective functions The controller is equipped with the following protective functions. 7.2.1 Collector protection If the storage tank has reached the set maximum temperature and the collector temperature exceeds the set collector protection temperature (line 1), the solar circuit pump is switched on. The solar circuit pump is switched off once the col- lector temperature is 10 K below the maximum value. -
Page 14: System Monitoring
System monitoring The occurrence of errors is generally indicated by a flashing symbol. 8.1 Sensor monitoring The connected sensors and sensor cables are monitored for interruptions and short-circuits. Errors are indicated by the symbol. The source of the error can be found by paging up or down in the Info menu. -
