Hi,

Was at a job today with multiple mitsubishi electric PKFY-P40VGM-E wall units controlled from G-50A central controller. The problem raised from the client is the fans constantly run all day, even when rooms are at temperature. Right enough fans stay on, at a lower speed than when heating or cooling.
Is this normal function on these units or can fans be stopped and only come on when heating or cooling is required. Most units I know work on this principle with pre heat and pre cool functions as well. This is raised as an energy saving issue.


Regards
