Calling up Parameters

Upon pressing the "Programming" key one of
the parameters numbers is displayed which are
listed on page 4 of this manual. Using the

Unlock Keys
To prevent un-authorized persons from editing
parameter values, there is a locking function
which allows only the setpoint to be changed at
any time. All other parameters must be unlok-
ked beforehand. This means that at parameter
P33 a certain value is to be set (---88---) :
- Press "P",
- Use " " to select parameter P33
- Press "P" again
- Use " " to set value to --88--
- Press "P" again to select parameter to edit.
If no key is hit for about one minute, the access
code is cancelled and the editing function is
locked automatically.
