Ive got 3 6100.10 pumps

One of the pumps has a 7240.26 driver
The other two have 7240.27 driver

Whats the difference ?

7240.260 was replaced by 7240.270 in late 2004. This was done to meet the technical needs of the wavebox and 6200. Both needed more power than the 7240.260 could handle reliably, we also added the fish care feature to prevent fish from entering a pump that was switched off.
