Hi Guys.
My Daughter in Law works in a Office where they have a AUYG30LRLE Cassette.

As I understand it the louvers are either locked in a particular Position or oscillate up and down.
This is causing issues for the staff in the airstream.
It appears that my answer of lock off the louvers in a new position
Using the control buttons on the controller is not possible as the buttons are inoperative?
(3 Button above flap concealed ceiling type controller)
In an old Manual I have it states that if buttons 13 and 14 are pressed the operation lock display flashes but the air conditioner will not respond?

Their A/C Engineer who I assume installed the equipment, has advised them it is not possible
disable the louvers.

I have no wish to dispute this as I suspect He is a knowledgeable and competent Engineer.

I have been advised that written on the System Information sheets it states that. -

A/C 4 linked to A/C 5 Control and vice versa.

Could this be the reason why the louvers on 1 unit cannot be altered?
Is it possible on this model to disconnect individual louvers within a cassette?

I would like to offer some positive advise but at the same time I have no wish to Diss! another Engineer.

Cheers Grizzly
