Solar Controller SR-R400 with 2 Outputs, 4 Inputs and Energy Yield for installation on a DIN rail

The solar controller SR-R400 is a high-performance, microprocessor-controlled unit for controlling solar thermal systems. It has two outputs and 4 inputs allowing additional featers like reheating and yield measurement.  

- Intuitive operating menu with graphic symbols and four operating buttons  
- Adjustable values  
- Integrated operating hours counter for storage tank charging  
- Start function for systems equipped with tube collectors  
- Integrated energy yield measurement    
(optional, only in conjunction with the yield measurement set)
- Solar circuit pump RPM controll or switching controll  
- Extensive functions for system monitoring that display symbols to indicate errors and faults
- Storage of all values even during a prolonged mains power supply outage  
- Various protective functions, such as system protection, collector protection, recooling and flow monitoring
- Generous wiring space
- Thermostat function (output 2).

 





If the collector temperature exceeds the storage tank temperature, the solar circuit pump is switched on. Monitoring and protection functions ensure safe operation.
The output A1 can be operated using an RPM control.
