What to do if my Wolf BM-Solar displays 'EEPROM fault'?
If your Wolf Control Unit displays an 'EEPROM fault', it indicates that parameter values are outside the valid range. To resolve this, reset the unit to its standard values by briefly interrupting the power supply, then check the values.
What does it mean if the Wolf BM-Solar shows 'DCF signal or reception interference'?
If your Wolf Control Unit shows 'DCF signal or reception interference', it means there is no BUS connection or no DCF reception. Check the eBUS connection and DCF reception to resolve this issue.
What should I do if my Wolf BM-Solar displays 'SM1: Terminal SFK, solar sensor Collector faulty'?
If the Wolf Control Unit displays 'SM1: Terminal SFK, solar sensor Collector faulty', it indicates a faulty sensor or lead. Check the sensor and lead, and replace them if required.
What should I do if my Wolf BM-Solar displays 'SM2: Terminal RLF, return sensor faulty'?
If the Wolf Control Unit displays 'SM2: Terminal RLF, return sensor faulty', it indicates a faulty sensor or lead. Check the sensor and lead, and replace them if required.
What should I do if my Wolf BM-Solar Control Unit displays 'SM2: Terminal E3, sensor on input E3 faulty'?
If the Wolf Control Unit displays 'SM2: Terminal E3, sensor on input E3 faulty', it indicates a faulty sensor or lead. Check the sensor and lead, and replace them if required.
What should I do if my Wolf BM-Solar displays 'SM1: Terminal SFS, solar sensor Cylinder faulty'?
If the Wolf Control Unit displays 'SM1: Terminal SFS, solar sensor Cylinder faulty', it indicates a faulty sensor or lead. Check the sensor and lead, and replace them if required.
What to do if the Wolf BM-Solar Control Unit pulse generator is faulty?
If the pulse generator of your Wolf Control Unit is faulty, it means that either the pulse generator or its cable is defective. Check the pulse generator and the cable, and replace them if necessary.
