Strange problem today
I went to a job today because the owner was unable to control his T-Stats remotely for his country home and when he went there to check the house after a few 0 degree days he reported that the T-Stats, most located in the boiler with the rest up in the attic were cycling or initializing in a slow delayed sequence. This made me think it was an AMX related issue cuz I couldn't think of anything else that could trigger this delayed sequence. Fortunately when I was there the rack UPS started beeping so I reset it and they it alerted me that the batteries were low, fortunately I brought batteries, transformer, etc so I replaced the batteries in the UPS the problem went away. I can only think it was some kind of under voltage issue because the dead batteries were draining voltage to the master and that caused the com port to cycle on/offline which in turn triggered the ViewStat comm module to init the T-Stats over and over again. Strange thing is that everything else seemed to be working fine, not that I checked very well.
