## Long description

FF AZ-112 is an automatic twilight switch designed to control lighting circuits at mains voltage.

How to use
Install the unit on a standard DIN rail inside an electrical enclosure and connect it to the 230 V supply and the lighting circuit following local wiring regulations. Position the external light sensor in a representative outdoor location free from local artificial light sources and pointing away from direct lamp glare. Adjust the threshold control to the desired lux level so the lighting switches on and off at the required ambient illumination. Verify correct operation by observing the relay switching at dusk and dawn conditions.
Usage recommendations
For reliable operation, mount the external sensor where it senses general ambient light without obstruction and away from nearby lights or reflective surfaces. Periodically check the sensor and wiring for dirt and damage and recalibrate the threshold if seasonal or landscaping changes alter ambient lighting conditions.
