2-CHANNEL BUTTON TRANSMITTER WITH TEMPERATURE SENSOR
RNK-22
TECHNICAL DATA
DESCRIPTION
The RNK-22 wall radio transmitter is used to send control signals and temperature value
related information in the extalife system. It is applied to realise the following functions:
switching on/switching off, brightening/dimming, roller blind control. The implemented frame
coding algorithm increases the safety of the transmission. Temperature value is displayed in
the mobile application due to the cooperation of the transmitter with EXTA LIFE controller.
The transmitter resembles a common switch due to its appearance and dimensions. The
battery backup and lack of wiring allows for its wide application. It means the transmitter can
be mounted on any surface (excluding metal surface) and in any place. By assigning a few
controllers to one transmitter it is possible to control the device independently from different
locations. During operation the LED green informs the transmission is in progress. The LED
diode is also used to signal battery discharge.
