The Wireless Solar Sync Receiver and Sensor are already paired with the same frequency for an easy installation. When installed, the wireless Receiver will automatically go into a “search” mode looking for the signal from its paired Sensor. However, it is a good idea to initialize communication manually between led the wireless Receiver and Sensor during installation to verify correct signal transmission.
Note: In the event of a power outage (or any other reason when the receiver loses radio contact with the wireless Sensor) the receiver will automatically go into search mode to re-establish communication with the Sensor once power is restored. However, when power is restored the controller will automatically go into rain shut off mode until communication with the sensor is re-established, which may be up to 60 minutes (maximum). Performing the steps listed above to validate receiver/Sensor communication will remove the controller from rain shut off mode and will return to its programmed irrigation schedule.
