Error Filter-H1 The filter heater is always in
operation when connected to
the system. However, it is only
monitored during active gas
aeration. In this case, it is
important that the filter
heater functions and this is
measured via the power
consumption. If filter heater 1
is disconnected from the
system (or defective) while the
Gasflow1 controller is active,
this alarm is triggered after a
few seconds. This does not
deactivate the controller. This
alarm message is only used 1x
per gas flow controller start.
You can acknowledge this
alarm message via the "Home"
button.

If the error continues to be
displayed even after a device
restart, you should contact a
service technician.
Make sure that the filter heater
is connected to the correct
output. If this error should
continue to occur, test the
function using another filter
heater.
