Roller shutter controller STR-22 single-button, Un=24V AC, 8A, surface or shutter box mounting

Roller shutter control – simple and functional

The STR-22 shutter controller is a compact device designed for convenient control of roller shutters (up-down) or other electrically driven devices. It is ideal for both new installations and for modernizing existing systems. The possibility of surface mounting or mounting in the shutter box provides flexibility during installation.

The controller allows for local control of a single roller shutter using a connected momentary switch, and also enables connection with other controllers in groups, allowing for central control of multiple roller shutters simultaneously. This solution will be appreciated by both individuals looking for a simple way to control the roller shutters in their home, and installers implementing more complex home automation projects.

Functionality and possibilities

The STR-22 controller offers a range of functions that increase user comfort and facilitate installation:

• Programmable run time: Allows you to set the motor running time, adapted to the size of the roller shutter and user preferences (range 0 seconds to 10 minutes).
• Settings memory: Remembers the last state of the roller shutter, allowing it to be stopped at any position.
• Power indication: An LED indicates correct power supply to the device.
• Universality: Designed for 230V AC motors, making it compatible with most roller shutters available on the market.
• Safety: Made of thermoplastic materials with high resistance to mechanical damage and external factors. Additionally, it is halogen-free, which increases fire safety.
• Compact dimensions: Facilitate mounting even in tight spaces (51x67x26 mm).

Installation and application

The STR-22 controller is designed for surface mounting or mounting in the shutter box. It has screw terminals 4.0 mm² providing safe and durable electrical connections. The device is adapted to work in a wide temperature range (-25°C to +50°C) and has a protection class of IP20, which means protection against touching with a finger and against the ingress of solid objects larger than 12.5 mm.

Thanks to its versatility, the STR-22 controller can be used not only for controlling roller shutters, but also garage doors or other devices powered by a single-phase alternating current motor.
