I am using external digital temperature controller (STC 1000) and Humidity controller (WH8040) Temperature controller works great throughout any range from sub zero to 70s. Problem is humidity controller tells me that my internal humidity is at 46 right now and varies to upper 80s for few minutes. I would say my average is about 70 RH. Is this fluctuation acceptable? Freezer is running empty for about 24 hrs. I think my fluctuation is because it's frost free unit and there is humidity on the coil. The heating element does not function because it's to warm inside. Internal fan was wired to run continually. So again is this humidity fluctuation a big issue? Thanks!
