About a week ago, I changed the min pressure from 4 to 5, and changed the ramp from 5 minutes to zero. Ever since then, sleepyhead reports the humidifier as 'disconnected' whereas previously it had reported it as 'connected'. The humidifier light is blue, the level is set to 4. I verified that the water level does drop overnight, but that may not mean anything.
Does anyone know what it means when sleepyhead says the humidifier is 'disconnected' ?
