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 automati- cally 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.
