    4 Solar circuit functions 4.1 System diagram Figure 2: System diagram The solar controller SOL3-1 is used to control solar thermal systems with one collector array and one storage tank. 4.1.1 Basic control functions The controller monitors the collector temperature (sensor CF) as well as the storage temperature (sensor SF) and turns the collector pump (CP) on once enough solar energy is available to heat up the storage tank.
  • Page 19 SOL3-1 Figure 3: temperature chart A) The collector temperature exceeds the storage temperature by more than the turn-on threshold (8 K). The collector pump is turned on. B) The collector temperature dropped below the turn-off threshold (SF + 4 K). The collector pump is turned off.
