Thermostats resetting spontaneously

Hi cocconers, for the last few days our thermostats have been resetting themselves to 62 degrees on their own. We had an extended power outage in the early part of the week, and I also installed optical repeaters in the data line between our OP2 and an expansion enclosure in another building. I have a feeling it has something to do with the power outage as only parts of the heating system were functioning during the outage. 

Yeah. I called Leviton and it had to do with the programming of the thermostat itself. Super simple. I forget what the actual steps were but I just called and they walked me through it.
