Lighting & PhotocellAstronomical Time Switch
Without needing to receive light, on any day of the year this device can accurately detect sunrise and sunset using a microprocessor program and control the lighting system with two outputs.
The astronomical clock has no eye sensor and can be installed in any indoor location.
The device's two output relays are independent of each other, and the delay or advance settings for switching on and off are set separately for each one.

Errors
Batt: internal battery depleted¹
Over: voltage rise
Under: voltage drop
1. The Batt error is sometimes caused by the clock settings being disturbed, and is resolved by resetting.
