Ok so I want to make sure I have things straight. Since the thermostat probe is supposed to be sandwiched between the UTH and enclosure (unless I'm mistaken), doesn't that make it lie against the foil used on the UTH? Is it ok as long as you're not taping up the metal tip of the probe? Sorry if these are basic questions! I've looked at several setup guides and there's some stuff I'm not fully clear on.
