Is it possible to reset a pump to the "00" address after it has already been assigned a number?

The quickest and easiest way to do this is to reset the pump. To do this:

• Turn the pump off
• Hold the right most arrow key down
• Whilst holding the arrow key down, turn the power on and keep holding the arrow key down for 5 seconds.
• Release the arrow key.

Your pump should now be back to address zero.
