Ok... so right now I am seeing what I guess is an ambient temp of 79 degrees inside my tub with a humidity of 61%. I have a space heater in the room as well. I have the flexwatt set to 92 degrees. What is going on? I thought I would be seeing 90 degrees on the hot side and low 80s on the cool side with my accutemp digital thermometer? If 79 is the ambient how do I find out the real temps?
