Explanation: The controller has not received temperature data from the weather station in the past 24 hours. If more than 5 days pass after communication was lost, the controller will return to basic mode.
Resolution: Relocate the weather station so that it can communicate with the controller more easily. Perform the Blink Test to confirm communcations from the intended mounting location. If the 4th Blink is green, you can communicate to the SLHUB inside the controller's cabinet from the designated location. If not you may have to reset the SLW5 hardware and try again. NOTE: **If you are getting this fault code and the "SLW Low Battery" fault code, the batteries will need to be replaced and relocation of the weather station is not necessary. If this issue persists or can not be resolved by moving the weather station, it may be necessary to replace the weather station.**
