The accpeted policy is to do an ADON learn run, and a shaft learn run, every 6 months. Also, on a KCM831 hydro, if you adjust the valve, you must do a shaft learn run again, because it records the "S-curve" velocities, even though the valve is only 2-speed.
Do you have the newer ADON board, the one with like 40 leds' on it, with each labeled as to function, and the white relays, -OR-, do you have the older one, with the clear case relays, and very few LEDs? The ADON 1 board is superceded, for good reason, not supported any longer, and the ADON 2 board is much more reliable.
