Warning level 3 is not output in the default parameter set (not configured).
Example for parameter set 1 'Balanced EU2' @ 55 ±5 ppm CO:
At 50 ppm CO, alarming must take place after between 60 and 90 minutes.
At an ambient temperature of ≥ 80 °C, the CO sensor may not function reliably.
Irreversible signaling of a critical fault therefore follows.
The FDOOTC241 may only be used in continuous operation within the specified
temperatures!
