I have been trying to figure out what the GRY 2/ AUX button is for on my Convenience Panel. I see a button for both grey tanks to check the level of each. I also have seen others post on the Coachman Owner's FB page asking the same thing. I have a 2019 Coachman Chaparral 298RLS, with 2 grey tanks and 2 drain valves.
Thanks for any info! Pic attached
Just a guess here, but I suspect it switches the gauge reading between the grey 2 and aux tanks. With the switch in the aux position, when you press the GRY 2/AUX button you are checking the level of the aux tank. With the switch in the GRY 2 position, when you press the GRY 2/AUX button you are checking the level of the GRY 2 tank.
Linear Mode
