Programmer for a doorkeeper

Doorman timer: The dust-proof timer is required to control the electronic doorkeeper and thus the door at a programmed time (opening and closing of the door at a preset time or opening the door at a programmed time and closing it at dusk).
When, in June in the northern hemisphere, it gets dark around 10.30 pm, you can, for example, use the timer to close the hatch automatically at 10 pm (factory setting). This makes it possible to close the hatch automatically before dusk arrives. If, a few weeks later, dusk arrives earlier, the flap will close automatically at dusk

The timer can power up to 3 electronic doorkeepers
