Now don't ask me why this happens given the program is supposed to be in static memory, but these programming problems seem to occur mostly with program A (resetting or just not working). Also had my share of problematic weather stations.
I have one right now the weather station (wired commercial grade) is no longer being seen by the controller. Haven't tried to troubleshoot it yet.
With all the bells and whistles they packed into the SL I never understood why there was either no battery-recharging circuit like the old ESP's or a lithium battery for the backup. Stupid to count on an HO to replace an alkaline battery twice a year. Also think the shut- down- when- opening- face plate thing is dumb.
The loss of comms with the weather station was the #1 problem with the WS - never had any problems with the SL using a Mini-Clik.
