I'm looking for a little help regarding my recent install of my gretz heated pitot. I installed it in my RV4 per the plans. The control box is mounted inside the wing near the pitot, and the optional LED light system is run to the panel. I am using a 10amp breaker switch at the main bus. When I switch on the master followed by switching on the pitot heat, I see two lights, red and orange. If I understand correctly, this indicates that the unit senses a low temerature environment and it's calling for heat. All seems to be working normally except the pitot does not even get slightly warm to the touch.
My questions are, what temperature does the unit ask for heat at? Current OAT is approximately 45 degrees farenheit.
Where would you start troubleshooting at this point?
Thanks in advance. Hopefully one day I have learned enough to be able to contribute more to these forums.
