From reading the clinician manual, I understand that when the ClimateControl mode is 'auto', the machine lets you specify a minimum air temperature and the machine will auto-adjust the humidity level throughout the night so that it keeps a constant 80% relative humidity at the specified temperature to prevent rainout. All fine and good. This is actually the mode I've been using so far. However, I think I'd like to try for some more humidity. Cue manual mode...
Now, when ClimateControl is set to 'manual', my understanding goes out the window. In this mode, the thermostat and humidity level controls are broken out separately. Temperature is the same; still makes perfect sense. Humidity though, is just a vague value ranging from "Off" to "6.0" in 0.5 increments. My gut feeling is that you're supposed to just set the humidity to whatever feels right, but then rainout becomes a concern.
Is it correct that manual mode forfeits rainout protection? Are you supposed to figure out an appropriate hose temperature to prevent rainout, and if so, what's the trick to doing that?
Is there a way to avoid all this voodoo and just instruct the S9 to adjust for a higher humidity level in 'auto' mode (without increasing the temperature too much)?
