13.8.4.2 Procedure for parameter
update
The information below explains how to work
with the "Update_function" parameter (see
parameter row 26 in the table above).
The update function makes it possible to
overwrite parameter settings with a parame-
ter set which is saved on an external USB
flash drive. As a result, the operator can
make a change without having to change the
parameters by themselves. The modified
parameter set can be provided by HygroMa-
tik.
The procedure is as follows:
» With the unit switched on, insert the
USB stick into the socket on the
mainboard.
» Call up the "Update function" in the
services submenu.
The status of the update process is displayed
(see table). Its successful completion is dis-
played by the "Update successful" status
message.
» Switch the unit off and on again. The
loaded parameter set is activated.
» To reload the parameter set at a
later date if required (e.g. after a fac-
tory reset), the "ImportDone.txt" file
on your USB stick must be deleted
beforehand. To do so, the stick must
be inserted in an external device
(e.g. PC).
If the status "Invalid data" is output after the
update operation, a compatible parameter
set is not available on the USB stick.
The parameter set that is stored on a USB
stick is always linked with a unit serial num-
ber and can only be used for this unit.

described for the basic level in Section

advanced level.
