Rear Heat Controls

This was my test wiring for rear heat control.

Rather than using old fashioned cables to open/close the heat valve, we are using a Linear Actuator Motor (Firgelli L12-P 30mm) to open & close the valve. This gives us the option of mounting the control anywhere we like. Including the overhead console.

There is a separate valve for heat going to the rear seats. The rear passengers will have their own heat control, but if there is no one in the rear seats the pilot might want to turn on/off heat in the rear without needing to reach into the back to turn the control knob. So this motor has 2 knobs... 1 for the rear passengers, and another for the pilot. A switch is used (by the pitot) to toggle which control know is active.

It works!
