I have a Pentair Water Pool and Spa Automation unit with 4 function remote. The in-laws stayed while we were away on Spring break and now the spa blower doesn't work. I can get the blower to work in Service Mode, but it will not work in Auto Mode. I think they turned a function or something on the remote off, and I don't know how to fix it. There is a button on the remote that you press to turn on the blower. Need help please!
