To avoid wrong wiring – the LT & PQ have automatic mode to swap the current line when it feels negative power.
In this auto mode – you can’t read import/export.
You should set the mode to ‘FIX’.
To set this goto Technical menu -> Wirring -> Current Lines and set it to FIX.
To do so in PQ goto Technical menu and when asked for password
Enter code 201 – for auto mode
Enter code 202 – for fix mode
Now – when the system is in FIX mode – double check the L&K current wiring – as the Elnet don’t swap it to correct wrong wiring..
In FIX mode the Elnet works correctly with Import / Export energy.
To check correct wiring you can also enter code 11 when asked for password.
