I've had my BP on a 500R thermostat until now and it has been fine, but lately for some reason it hasn't been getting the temp above 88-89f, even with the dial cranked all the way. It's not the mat, because if I plug it in by itself, it reaches well over 100f.

I finally got pissed off this morning after spending an hour screwing around with thermostat probe placement, and ordered a prewired Ranco and an UltraTherm UTH from RBI. I guess I will relegate the old thermostat to a new snake with lower temp requirements (corn) or use it to control a UTH on the cool side of the tub. I'm not sure yet.

Anyway, are there any tips I need to know about setting the Ranco up?

Thanks!
