It looks like the difference is the 4006 is a SPST and the 6006 is a SPDT. How many things are you controlling with the aquatstat. if it is only the fan then the 4006 should be fine.
I need help troubleshooting my fan. I can't get it to kick on. It was working fine before the OWB overheated. Any suggestions where to start?
