This symbol (see pic) showed up on my Intermatic RC2163BFE Pool Controller. I have no idea what it is and I can't find any useful instruction manual online. There was a power outage the day this symbol appeared, but I have had plenty of power outages since I've lived here and this is the first time I have seen this symbol. The pump did not turn on when it should have today, but I was able to start it manually and since then it seems to be working correctly (it shut off at the correct time today). Any ideas?
