I'm trying to track down a replacement controller for an older Velux electric skylight, originally a WLC 160/100 which isn't made any more. Some of the more recent ones like the KUX 110 aren't compatible any with older skylights, but slightly older ones like the KLC 500 apparently are. Does anyone know what can be used to replace a WLC 160, what's in one (it looks like it's just a 24VDC power supply controllable by a remote), or anything else that might help getting the skylight operational again? The original WLC 160 it came with is (physically) gone so it's not a case of repairing it, unfortunately.
