I hooked up my Ranco thermostat tonight and got my thermometer in there as well. Now I have a couple questions about it all....

First, when setting the temp on the actual thermostat do you select heating or cooling? I put my temp in at 94 degrees with a 3 degree differential. Is that ok or should I change it?

Second, I have the thermostat probe between the tub and the UTH. I have the thermometer between the tub and substrate. Thermostat says 95 degrees and thermometer says 88 degrees. Should I bump up the temp on the thermostat til my thermometer reads 94? I am a tad confused.

Third, in my glass tank set up our hot side is staying at 93-94, our cool side is at 78 degree with a heat lamp on it. Our humidity level is at 38%. Top is covered with foil, the heat lamp is partially on the foil and on the screen top to not add too much heat and kill our humidity. Any advice on making the temp and humidity better? And what is a good humidity level?

Thanks in advance for any and all help!
