RESET - Deregistering all devices paired with the RTH receiver In order to deregister all devices paired with the RTH receiver, simultaneously press both the pairing and the deregistering button and ) and hold them for at least 5 seconds until the LED flashes alternating red and green. Then release both buttons. A properly completed process of deregistering all devices is signalled after approx. 2 seconds by the LED colour changing to green and then switching it off fora short period of time. Signalling operation and reception of data packet Each radio transmission received by the AURATON RTH receiver from the paired device is signalled by a temporary change of LED colour to orange. Switching on the relay is signalled by the LED lit red, whereas switching it off is signalled by the LED lit green. LED NOTE: If after executing the RESET function the RTH receiver is disconnected from power supply and then connected again, the receiver will automatically enter pairing mode for 120 seconds. A newly purchased RTH receiver without any factory-paired devices (i.e. not the one bundled with the regulator) will behave the same way.
