NIBE · SMO 20 Control Module
An alarm occurring in the F2120 outdoor unit could trigger a translation error, which then incorrectly reported a communication error to the NIBE Uplink system. This false error could also affect functions like periodic increase.
Click steps to track your progress.
Check the F2120 outdoor unit for any specific alarms or status messages on its display.
Verify the communication cable between the F2120 and the indoor unit/control module is secure.
Update the NIBE SMO 20 firmware to version 9303R7 or later.
If the error persists, contact NIBE support or a qualified technician.
