Daikin Binding in OH2?

The wiki

// mode of operation - one of Auto/Dry/Cool/Heat/Fan/Night
String  DaikinMode   "Mode [%s]"       { daikin="<name>:mode" }

appears to disagree with the code:

    public Class<? extends Item> getSupportedItemType() {
        switch (this) {
            case POWER:
                return SwitchItem.class;
            case TEMP:
            case TEMPIN:
            case HUMIDITYIN:
            case TEMPOUT:
            case MODE:
            case FAN:
            case SWING:
            case TIMER:
                return NumberItem.class;
            default:
                return StringItem.class;
        }
    }

What does your items file specify as an item type?

I intend to overhaul this binding once I have the hardware to integrate my heat pump with openHAB.
