I am trying to find the installation / operating manual for my Lossnay MVHR unit model KAR-50RSDC I have the manual already for the LGH-50RSDC which seems easy to find and download, but it is different, with a different type of controller PCB.
The issue I am having is I cannot manually select summer bypass mode. My unit has two inputs called "heat" and "cool" (which the connection diagram says refer to bypass condition select) and it does not matter which I select, the bypass mode does not turn on.
I have just finished the ducting and giving the unit a basic operational check and frustrated I can't operate the bypass mode.
Anyone have the manual for the KAR unit or have one working please?
