Note: An optional output PCB for the indoor unit can be added to provide output
for external device. The output PCB will trigger in case a leak is detected. For exact
model name see option list of the indoor unit. For more information about this
option, refer to the installation manual of the optional output PCB
Note: iTM and WAGO module can also be connected to generate an output signal
in case of leak detection. E.g. it can be used at a supervised location. Please refer to
installation manual of the iTM for further details.
NOTICE
The R32 refrigerant leakage sensor is a semiconductor detector which may
incorrectly detect substances other than R32 refrigerant. Avoid using chemical
substances (e.g. organic solvents, hair spray, paint) in high concentrations, in the
close proximity of the indoor unit because this may cause misdetection of the R32
refrigerant leakage sensor.
