I have a AC high flow meter buti get very different results when i use the recommeneded setting of 169 impluses in my aquaero 4.0 and my power adjust 2.0 ultra version.
does the pa2.0 ultra use's a much more precise sensor and thus needs a different calibration setting compared to the aquaero 4.0 or is it simply I have a malfunction sensor as the AQ 4.0 reads around 120l/h where the PA 2.0 reads 300l/h when i switch the flow sensor connection between the two/
