If you are experiencing display problems with your STIEBEL ELTRON Heat Pump, you can try the following steps: * Delete the EEPROM memory of the control unit. * Reset the control unit by briefly interrupting the power supply. * Reconnect the power supply while keeping the 'OK' sensor field pressed during the start screen. * Release the 'OK' sensor field once 'EEPROM RESET TERMINAL' is displayed to complete the reset.
