ResMed S10 warming up question ??

[GrammaBear]

After using my 'gently used' ResMed Airsense S10 Autoset for Her for several weeks now, I find that each morning I have to refill the humidifier tank.  I have the humidity level set at 5 which was basically a number I picked out of the blue sky.  Is this normal for the machine to use that much water in one evening?

I also think the machine is set to 'warm up' and I don't know if that is a good thing or a bad.  Should I be turning off this feature and if so, how do I do that?

I dont use the warm up . I also have mine on auto with heated tube. In 8 to 9 hrs i use about 3/4 or so of water. To adjust it it under my options the climate control

Thank you for your help, it is nice to know how much water someone else's machine uses. I thought mine might be using too much.

I run 1/2 to 3/4 tank in a night.

I would suspect that the more pressure you run, the more air flow going over the water, and hence, more evaporation.  My pressure is 5 and 20, but it pretty much runs around 10-12.  Another factor, is it dry in your room??? 
I have my setting at 8 and I while I only fill the tank half way, I always have plenty of water left over in the morning.
