hey there
just recently purchased the 2500
I'm not sure if anyone knows much about them as they are a new unit. But i was fidling around with it and i set the fan mode to cont. Which in the manual says it runs the fan continuosly. When i set it to it i couldnt for the life of me hear the fan. I know on my old 1400 i could hear the fan distinctly but not so much on the 2500. Could it be that the fan is so quiet you cant hear it? Or is it somthing else?
