  1. James,
    Your Senville mini-split system showing a (df) code usually means it’s trying to defrost itself, thinking there’s ice even if you can’t see any. The double dashes (–), which aren’t explained in the manual, might mean there’s a problem with how the inside and outside parts talk to each other or a small glitch that needs resetting. You can try turning the whole system off and on again to see if it fixes the issue, make sure all the indoor units are set to the same mode to avoid conflicts, and check that all wires are connected properly and not damaged.

  2. I have the Senville 36k BTU compressor with 3 – 9k BTU wall units installed.
    Everything has worked great until but sometimes I get the (df) code and have no reason why because there is no evidence of any icing on the outside compressor unit.
    Also all 3 of the wall units will sometimes display the 2 dashes (- -).
    I’ve looked through the manual and it says nothing about the dashes. HELP !

    Michael Miller,
    An EC error code on a Senville mini split will happen when the unit sees or senses a refrigerant leak.
    This can be from a faulty temperature sensor, leakage or blockage in the lines, or a malfunctioning indoor main board.
