The standard time switch with practical display enables the time control of tubular motors with mechanical end position adjustment. It is not only suitable for the Schellenberg standard and PLUS tubular motors, but also for roller shutter motors from other manufacturers. The setting as well as the manual operation are facilitated by large keys and a well readable display. In addition to manual control, the Standard timer has a daily and random program for automatic time control of a roller shutter.In the day program, individually selected, automatic opening and closing times can be set for working days, Saturdays and Sundays. It is possible to either store two times or activate only one opening or closing time if you want, for example, that only the morning of the roller shutter opens automatically.The random or holiday function can be switched to the day program. The automatic opening and closing times are then selected by chance and deviate by up to 15 minutes from the time set in the day program.Manual operation remains possible at any time despite an active schedule. Depending on the need, it is also possible to switch between manual and timed operation at the push of a button, for example to avoid lock-out. In manual mode, the daytime and random programs are deactivated and the blind can only be controlled by pressing a button. The summer and winter time are independantly set by the time switch and in case of a power failure the data remain stored for 2 hours.The standard time switch is flush-mounted in a switch box with a diameter of 60 mm. With Schellenberg surface frame for control elements, surface mounting is also possible. Two screws are included in the delivery for fastening the time switch in the switch box.This text is machine translated.
