2000 Ovation Pitot Heat Question Flying in light icing conditions near Rock Springs WY yesterday with OAT -1C I had pitot heat switched on. And the TKS in operation. Everything going fine, the protected areas were clear and ASI normal. But after a few minutes I for some reason happened to touch the area under the panel lower edge just above my left leg. I felt a metal box or bracket that was quite warm, too warm to touch for more than a few seconds, so I guess it was at least 50-60C. I aimed some air from the left vent at the hot spot. A few minutes later and out of the clouds I turned off the pitot heat. The metal cooled off rapidly. i took a picture of the area. It is an aluminum bracket with some electrical component bolted on the top, non-visible side. Anyone know what this is, or have a schematic for the pitot heat? Is it a thermal switch or current sensor? And should it be so hot in normal operations? The part is marked 802338-501 but that is just the metal bracket number.

Does anyone know if there is a limit on the number of pitot / static requiring devices ? Looks like more and more devices need those inputs . Encoder, VSI , altimeter , airspeed switch , G5 or SAI-340 . whats the cleanest way to install in order to avoid a bunch of tee union ?
