2-channel bidirectional radio key transmitter Type: RNK-22 EXL10000005

Radio frequency key transmitter for smart home

This two-way radio frequency key transmitter RNK-22 is an element of the Exta Life system, designed for wireless control of various devices in your home. It allows convenient switching on/off of lighting, blinds, and also adjustment of their intensity. Additionally, the built-in temperature sensor allows monitoring of conditions in the room and using this data to automate the heating system.

The transmitter is distinguished by its easy installation – it can be placed on any surface (excluding metal) and in any location. Battery power eliminates the need to run additional wires, which greatly simplifies installation. The ability to program multiple transmitters to one receiver provides great flexibility when configuring the system.

Versatile application and user comfort

RNK-22 is not only a remote control for devices. The built-in temperature sensor transmits data to the EFC-01 controller, enabling the creation of an intelligent heating system that adapts to current conditions. Thanks to this, you can optimize energy consumption and ensure thermal comfort throughout the year.

• Remote control: Turn devices on and off, brighten or dim the light, and control blinds without having to get up from the couch.
• Temperature monitoring: Track the temperature in the room and use this data to automate the heating system.
• Easy installation: Battery power and no need to run wires make installation quick and easy.
• Configuration flexibility: The ability to program multiple transmitters to one receiver gives great freedom when creating a control system.
• Transmission security: The implemented frame coding algorithm increases the security of signal transmission.
• Optical signaling: The LED indicates signal transmission and battery status.

Technical specification for professionals

The RNK-22 transmitter operates in the ISM 868 MHz band using two-way data transmission at a speed of 9600 bps and coding based on a 128-bit key. This ensures stable and secure communication with Exta Life system receivers. The operating range in open terrain is up to 300 meters, and the temperature measurement range is from -40°C to +125°C with a resolution of 0.1°C and an accuracy of 1°C (in the range of 0-85°C) and 2°C (in the range of -40-125°C). The device has a protection class of IP20 and protection class III, which ensures safe operation in domestic conditions. It is powered by a CR2032 (3V DC) battery. The dimensions of the transmitter are 90 x 80 x 11.5 mm, and its weight is approximately 40 grams. The device meets the standards PN-ETSI EN 300 220-1 and PN-ETSI EN 300 220-2.
