the room temp. ranges from 70-75 depending on if i turn on my heater or not. The humidity is good i know how to control it for the most part .. 50-60 perfect imo. the Temp im having difficulty with since i dont have anything reading the Hot side, im totally relying on the control unit probe. The cool side therm seems to be reading 75.6 and the dig thermometer/hydrometer inside is reading .4 more 76.0.
