    I believe ours is mounted in the vertical configuration and my son thinks the UPM board is on the bottom and very difficult to get at. I can't really tell from the manual where it is, but you'd think there would just be a removal panel on one of the sides you could get at.
    Bosch Water Source Heat Pump Model
    Serial: 2940-457-000001-7735019699

    Each unit is provided with a factory installed Unit
    Protection Module that controls the compressor
    operation and monitors the safety controls that protect
    the unit.

    On another SM Bosch unit, the electronics board seems easily accessible.
