An astronomical timer is a general term for instrumentation that indicates time ‎signals related to the celestial bodies. Such clocks, which are very much used, ‎are those that indicate the sun’s setting and rising times, and used for ‎determining the times for switching exterior lighting on and off, mainly in urban ‎and inter-urban traffic routes. The B120 is an astronomical timer designed for ‎timing outdoor lighting.‎

A light sensor can be damaged by exterior events (such as, for example, bird ‎stools or ‘Graffiti’ spray paint), that will cause the lighting to switch on for a longer ‎period of time, which wastes electricity and energy. The B120 does not require ‎connection with exterior light and therefore is not affected at all by any exterior ‎phenomenon.‎

With a Shabbat timer, changing the switching on and off times is necessary, ‎according to the sunrise and sunset, every time. With a B120, no readjustment is ‎necessary. This advantage saves the time and cost of an electrician’s work and ‎in addition, saves electricity since it switches on and off every day according to ‎the sunrise and sunset.‎

What is the accuracy percentage of the device and which conditions does it ‎withstand?‎
The B120 accuracy is 1 minute per year at 0-40 degrees Celsius, and 1.7 ‎minutes per year at -40 to 85 degrees Celsius.‎

1. The B120 is more accurate than its competitors.‎
2. ‎The B120 is smaller and takes up less space in the electric cupboard panel.‎
3. ‎In order to arrange the deviation times, the B120 has a miniature terminal with ‎a large screen and several buttons. This feature prevents unwanted persons ‎from operating changes on the B120. Additionally although the B120 has small ‎dimensions, the Terminal a large screen, which is convenient to view, and easy ‎buttons for making changes.‎
