Hello there
Thank you very much for this well detailed and well presented video. I recently bought this amazing pump controller and am yet to install it.
I have a question. On the terminals 1,2 3 how do i connect a float switch ? i intend to install a float switch as opposed to the liquid level probes

We want to know how to install it in line with timer and also without any liquid level control
