- Delta T Cotrol - When the switch-on difference is reached, the pump is
activated until the differential temperature drops below
- Maximum tank temperature - When the adjusted maximum tank
temperature is exceeded, the pump switches off
- Collector emergency shutdown - If adjusted collector temperature
is exceeded, the solar pump is switched off
- System cooling - If the temperature rises to the maximum collector
temperature the solar pump remains on until the temperature drops
- Minimum collector temperature - a minimum set temperature
which must be exceeded before the solar pump is switched-on
- Antifreeze function - If the adjusted temperature drops, the solar
pump is switched on to protect the fluid from freezing
- Tank Cooling Function - In the evening, the solar pump continues
running until the storage tank is cooled down
- Tube Collector Function - The controller measures an increase of heat
rise in the collector and adjusts operation for maximum efficiency
- Heat Generation Measrurement KWh (BTu) - The heat generated is
measured by the flow and the temperature of feed and return sensors
- Operating hours counter - Operating hours counter stores the
solar operating hours of the respective relay
- Manual operating mode - For control and servicing, the operating
mode of the controller can be switched manually
