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. 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.
Remote control
By downloading the Memo application, thanks to the Bluetooth interface, it is possible to pair smartphones and tablets to the device. The possible functions are varied:
- Create programs directly on your smartphone
- Transfer created programs to multiple memo clocks
- Capture programs from a memo and copy them to another memo with the copy/paste command
- Switch the relay outputs manually
- Capture settings such as date, time or coordinates automatically and transfer them to the memo
How the product looks like
The device has the size of 2 DIN. There is a large backlit display on the front of the switch to display the date, time, relay status, and textual guidance.
Keypad lock function
The device has a "keypad lock" function with password, which is useful, for example, for installations in public places, prevents settings from being changed by unauthorized persons.
Vemer also provides Memo BT2, with hourly (daily or weekly) or astronomical programming.
Other power supplies are available for all models on request.
