Information and remedy
Errors F0-, EP- and E2 can only be repaired in the factory, if the function cannot be restored by switching it off and on. Errors F2, F3 and F4 can appear on equipment with external or analogue nominal value statement as "Setpoint error". In this case, the connection must be checked.
If variable values are shown with "L--" or "H--", this is usually due to a fault occurring where the value range shown is not reached or is exceeded. Here, you can try to restore the desired value by holding down for a longer period the SET + ON or SET + OFF buttons.
Unlisted messages are usually EEPROM errors. There are different error messages for the ranges TRK, TRL, TRM, TRS and TRW.
There are additional controller-specific error messages in the data sheet for your controller.
This error is caused by fault spikes. Please isolate the controller from the mains for approximately 20 minutes. There is more information in the installation notes for your controller.
