What is a time/astronomical switch?
A time/astronomical switch is a device designed for control the switching on and off of electrical circuits according to preset times and environmental conditions such as sunrise and sunset. This device combines the functionality of a traditional time switch with that of an astronomical switch, allowing more precise and flexible control of electricity based on both programmable schedules and daylight conditions. Time/astronomical switches are usually used for automated control of outdoor lighting, such as illuminated signs or garden and park lighting. They can also be used to control irrigation systems.
How it works
The time/astronomical switch works thanks to a timer that allows you to set the desired switching on and off times and thanks to a software inside the device, which allows it to calculate when the sun rises and when it sets. This is possible thanks to programs inside the instrument that allow it to analyze the latitude and longitude at which the device is located, depending on the geographical area set. Memo KNX offers the possibility of connecting via BUS a GPS module (GEO-1, purchased separately) useful for receiving signals from the satellite system to acquire precise information about the device in which it is integrated, such as time, date, and geographic coordinates (latitude and longitude).
The astronomical twilight switch battery has a life of five years and can be easily replaced when exhausted thanks to the flap on the back of the device.
Why choose Memo KNX
The KNX system is based on a serial communication bus through which KNX devices can exchange data between each other. This system allows users to integrate and control a wide range of functions within a building, including lighting, heating, and more. KNX devices have the great advantage of being able to be installed and uninstalled without the need to make significant changes to the infrastructure.
Memo KNX allows to drive 9 different channels on Konnex bus; the programming of channel 1 is also replicated on the relay of the KNX memo. Each channel can be associated with a different programming, hourly or astronomical.
