The control of the Condair GS/Condair GS...OC checks whether there is a temporary problem (e.g. gas supply interrupted for a short time) or whether it can re- solve the problem by taking necessary measures. If the cause of the malfunction disappears of its own accord or if the control can repair the malfunction, the alarm message will automatically switch off. If the cause of the malfunction does not disappear even after a longer period of time, a fault message is triggered. – Fault message (additionally to the fault message the red LED lights) Fault OTF: Over Temperature Lockout Menu Info Further operation is not possible any longer, the unit is blocked.
