Alert: SLW Communication Error
This alert is generated when the weather station has failed to communicated with the controller.
What might happen as a result of the issue?
The controller will continue to operate in Auto Adjust mode, calculating run times as normal based on the last data received, for 5 consecutive days without communication.
After 5 days, controller will automatically change to Standard mode and begin watering based on standard run times.
After 5 days, you will also receive a NORMAL to NONE SLW error indicating there is no SLW attached and steps must be taken to re-sync devices.
This problem can be caused by a number of different issues.
Poor radio signal between controller and weather station: See here for tips on placement.
Weather stations batteries have failed: See here for battery replacement.
SLW hub not fully inserted: Check hub connection.
Damage to weather station antenna: Replace weather station.
Local radio signal interference: Weathermatic's weather stations operate at 900 MHz. This band is used by some walkie-talkies, older cordless phones, and some amateur radio operators. This devices will need to be turned off or relocated if possible.
Damaged wire path (wired models): The damaged wires will need to be cut and spliced into new wires.
Alert: SLW Temp Data Error

Reboot of weather station internal processor: See here for battery replacement.
