Hello Mike,
Your Advanced Control Module can be reprogrammed to run in position mode, yes. The system has four programmable position stops, so you would actually want to set your RV-10 flaps up for reflex, 0, 15, and 30.

You can engage this mode from the SET--> CAL--> Flap Position menu. Change Operation Mode from "MOMENTARY" to "POSITION", and press SAVE. From this page you will also need to program the calibration points for each of the four stops by physically moving the flaps to the reflex position for FULL UP, 0 degrees for POSITION 1, etc., and then pressing COPY for each position stop which corresponds with the physical flap position you are trying to record.
