using the [Up] and [Down] buttons, and press [OK]
to switch to the corresponding menu.
There are two types of access rights:

operation.
The owner of access rights may do the following:

all settings including calibration data.

• parameterise the controller
• alter alarm settings
• run the device manually.
2. Select the desired type of access rights, and
press [OK] to get to the corresponding menu.
3. If an old code exists, confirm the old code
number first (on first use, confirm code 0000).
4. Select "change".
5. Enter the old code in the submenu (see the
comment line at the bottom of the display) using
the [Up] and [Down] buttons, and press [OK] to

submenu.
• Entering a valid four-digit code number gives the
operator access to the corresponding functions
for a limited time of 60 minutes.
• If no code was entered previously, the desired
menu can be accessed without restrictions. The
code number 0000 will not be displayed / the
operator will not be asked to enter it.
11.5.9 Reset function
• Entering the code number "1998" deletes all
previously entered code numbers.

to the "display"
menu using the [Up] and [Down] buttons, and
press [OK] to confirm.
11.5.11 Saving / accessing user settings
In the "factory setting" submenu, the current device

from the menus (not just the "setup" settings).

saved setup.

Note
If a wrong code is entered, access to the
corresponding menus is denied. An error
message is triggered (duration: five
seconds), and the device will return to
"main menu".
Note
If the contrast setting is too high, it may not
be possible to read the display. Hold down
the [Down] button until the contrast setting
is low enough to be read again.
Note
In this menu, save your device settings
once you have set all the values in the
"setup", "controller" and "alarm" menus.
You can then activate them again at any
time (even after a factory reset)!
