===== General description =====

The universal lights dimmer LD-P4-HIQ is 4 channels controller for [[en:hiq_hw:lud12-iq|LUD-12]] universal light dimmers.
LD-P4-HIQ supports local control buttons or potentiometers connected directly to it, which can be mixed and are auto-detected.

Many features are available in the stand alone mode, while advanced features like scenes, scheduling, smartphone operation, internet connection are only available when connected to the appropriate Home Controller.

[[en:hiq_hw:lud12-iq|LUD-12]] universal dimmer can be used for any type of dimmable 230 VAC lights. It automatically detects load type (L loads and C loads). Dimmer is electronically protected against overload and over-temperature.
