The range of communication between thetransmitter and the receiver in an open area is up to 60m. The radio transmission is influenced by many factors that can shorten the working distance, suchas thick walls, drywall covered with aluminum foil, metal objects such as cabinets, general radio interference, etc. However, the range is sufficient for mostdomestic use. It is recommended to test the radio transmission between devices before mounting the regulator on the wall. The test can be performed bychanging the set temperature, i.e. by activating or deactivating the heating.1 2 34 5If you purchased an RXRT510 or RT510TX and intend pairing with other devices in the 5x5 range, please refer to the Receiver Units manual or therelevant manuals available at www.salus-controls.eu
