Infra-red communications head WFZ.IRDA-USB
When communicating via the infra-red communications head
WFZ.
IRDA-USB
with an
EWA600C-RF...
, an unintentional communication
attempt with the heat meter is possible.
This generates a temporary hardware error in the heat meter and this is indi-
cated in the
HMA suite
.
This error is reset in the heat meter after approx. 1 minute.
To avoid this we recommend covering the IrDA interface of the heat meter
during communication via the infra-red communication head
WFZ.IRDA-USB
.
Change between S-mode and C-mode
To change the modes, you need the
HMA suite
, a PC and the infra-red com-
munication head
WFZ.IRDA-USB
.
