Transmission range
The radio transmission range is limited by both the distance between transmitter and receiver, and by interference. Indoors, building materials play an important role. Major reflections and signal losses are due to metallic parts, such as reinforcements in walls and metallized foils, which are used on thermal insulation products.

Other interference sources
Common sources of interference are devices that generate high-frequency signals. These are typically computers, audio-/video systems, electronic transformers and ballasts. The distance of the actuator to such devices should be more than 0.5 m.
Loss of communication with the room controller
If the actuator cannot establish a dependable radio communication with the room controller, i.e. more than 6 times in sequence the room controller does not receive a radio signal, then the actuator switches to a reduced radio pattern. The typical 10 minute radio period is extended to one transmission every hour, reducing the energy consumption while radio contact is interrupted. In addition, the actuator enters the safe position. Once the radio contact to the room controller recovers, the actuator reverts to requesting instructions from the controller every 10 minutes.
