How to use

Install the TWILIGHT SWITCH VZH-01 inside a suitable electrical enclosure or control cabinet, following local electrical regulations and safety practices. Connect the device to the lighting circuit and supply according to the system wiring diagram supplied with the product. Adjust placement so the sensor has representative exposure to ambient illumination; avoid directing the sensor toward local light sources that could cause incorrect switching. After wiring, verify correct operation by observing switching at dusk and dawn or by simulating low and high ambient light conditions.

Usage recommendations

For reliable performance, locate the photocell where it senses natural ambient light without direct exposure to nearby lamps, reflectors, or transient light sources. Periodic inspection and cleaning of the sensor area will help maintain correct switching thresholds. Ensure installation and maintenance are performed by qualified personnel in accordance with applicable electrical codes.
