LG Dry Contact Issue

[scottmcgurk]

Hi all,

Im working with 3 units and fitting an LG PQDSB to each indoor coil to switch a booster fan. (The indoor units are MB09AHL's)

Connected to the CN-CC port on the main board, as per the manual - but no life from the board.

I could believe a faulty board, but not 3, and not on every unit!
Is there something I've to do on the controller to enable these boards?

Cheers

Scott
