Forgot to mention something else, putting the thermostat probe under the panel and setting to 90F works much better if your room is relatively warm (75F+ consistently) HOWEVER, putting the thermostat probe on the cool side and setting to 80F seems to work better if your room is cooler (65F-74F). This is just what Ive found from years of tinkering with the setup. Others might have something different.
