suse - i have no idea waht it is set at. It is a split system
i cant have the fan on in his room as i have the breathing monitor on and it sets it off....
I think most split systems default to run in 'auto' mode.

Wow, I didn't know that the breathing monitors can be set off by a fan. We never used a monitor, or we would have found that out very quickly; we always used a fan in Euan's room, he was born at the start of the wet.
