Evening All, long time lurker, first time poster!
I've a customers who's just had 3 LG MB09AHL's installed.
The ducting run lengths are causing pressure drop, and more of a drift of air from the diffuser!
I intend to fit an in-line booster fan, but to ensure it wont run all the time I'm trying to pick up a fan run signal from the unit.
I know the LG has an expander pcb for dry contacts (PQDSB) which will give me a run signal, but I'm concerned this will only supply an indication that the unit is on, and give rise to some nasty draughts when in defrost from heating!
Anybody any experience or thoughts with this?
