I leave the humidifier on 'Adaptive' and 3 out of 5 setting, sometimes lower if it is hotter and humid in the bedroom (it is summer in the USA).
I thought everything was working OK, and I left the windows open and it got unexpectedly cooler in the room (61 F) as a cold front went through. Normally never gets below 70 F in summer and 65 F in winter.
I woke up this morning with what felt like ice cold air blowing through my full-face mask (no condensation in the hose). I opened the humidifier compartment and felt the water and it was very cold.
The humidifier does heat the water if I place the setting in the 'pre-heat,' setting so it is not dead.
Any idea if this is normal behavior? (The humidifier not heating at all in a cold room). Is it ever normal for the water to be cold?
Any way to test if the humidifier is working correctly in adaptive mode. Is there a minimum water temperature or something that I could measure in the morning?
I am not sure if I would notice if it was not working correctly this time of the year, as it is normally humid and warm in the bedroom.
The machine does have a manual humidifier setting (instead of adaptive) with settings 1-5, but I was advised not to use it by the medical device dealer (said it was hard to control and could cause "rain-out").
Anybody use the Dreamstation in 'manual' humidifier mode? What setting?
What does 'adaptive' adjust (water temperature? exit air humidity? exit air humidity/temperature combination?)
