I have a 1994 U280 Unihome. It has a hydro flame monitor with 4 sensors. #1 monitors the propane tank for leaks, #2 is the CO monitor, #3 is labeled Aux 1 and #4 is labeled Aux 2.
Aux 2, #4 is on displaying a red light. Does anyone know what Aux 2 monitors and why it might be on. Any info on what Aux 1 monitors would also be appreciated.
Thanks, Dick Boggs
