Have a Down East hottub, either 2001 or 2002. Was playing with the panel the other evening and it popped up with F1 thru F12. I didn't know what this was and now the tub is running constantly and I cannot figure out how to get back to the F's which I now know is for pump duration. This was a used hot tub and did not come with the owners manual and the company says they do not have one?!? So, does anyone have an owners manual that you can help me with the programming. It has 4 buttons, up and down arrow, jet and light button and a temp readout.
