At 17:29 had a Air handler MY alarm handler alarm go off. Attached last weeks trend of the MY temperatures: Blue: Heater temp, Orange: VEA temp, Green: Outside temp.

It seemed Bubba changed the heater temp on the 15th (13:30 UTC)  as in alog 54516 but since the 16th 13:00 UTC the temp of the heater has been cycling every ~5-7hours from 80deg to 115deg. Is this expected?
