To reset the system, disconnect the power supply for at least one minute.
If 10 minutes elapse after an alarm without any other malfunctions occurring, the alarm counter is reset
and three new attempts are possible.
If two or more alarms are triggered simultaneously (e.g. due to motor overtemperature and lack of water),
only the first malfunction signal received by the control board is signaled.
WARNING ! The converter does not have a non-erasable alarm log, we therefore recommend that you
observe the flashing frequency carefully before disconnecting the power supply to the TKS
system.
For further information refer to chapters 8.1 and 12.
