    LG Multi R32 Aggressive Air Offs in heating mode



    Anyone had complaints about R32 air offs being too hot in heating. Compressor discharge is 94c and pipe in temp to indoor units at 71-75c meaning air off of nearly 60c indoors it's an uncomfortable heat. Indoor units just cycle on and off as never ramps down, uses more energy than the R410A unit that it replaced.

    I'm using a Daikin R32 split at home in our rear lounge and don't have any unusual system temps.

    High discharge temps can be a symptom of a lack of lubrication in the compressor, causing the comp to run hot, thus increasing discharge temps.

    Normally, when the discharge temp reaches 103/106C the comp starts to ramp back in protection mode.

    Is this something that has occured recently ?
