Hi Bob,
The power supply is good, I have two cork tiles on the back as insulation and a Fotek 60A SSR. At least I thought it was a Fotek, but just recently the relay started to show signs of melting! Last night the hot bet heated and heated ans heated, although the relay controller has commanded the relay off, it continues to heat. A little research shows I have a "knock-off" relay, so that may explain its demise. What relay do you have?

I am building up a MOSFET switch for temp/permanent use depending on performance. That's probably my last work for a while, we're off to our RV on the Alabama Gulf Coast for 3 months, thanks for your help in getting my system up an running over the last few weeks.
