Do you have a CHE? Get a thermostat. put a CHE towards the cold side and put it on the thermostat. set your UTH at 94 degrees. Set the thermostat at 82, and put the probe in the cold corner.
I would not move the UTH in the middle. 1.) you will proably destroy the UTH. 2.) If you are able to move it without destroying it, you setup will be WRONG. There needs to be a hot side.... and a cold side. not a hot middle, with warm sides.
