the thermoSTAT probe is placed between the UTH and the glass, the UTH is plugged into the thermoSTAT and monitors the UTH temp and the thermoSTAT adjusts accordingly to what it's set at.
the thermoMETER probe is to get the temperature of the inside enclosure floor.
my thermoSTAT is set to 94°, and by the time it reaches the thermoMETER probe inside the tank, it's at 90°.
thermostat controls temp, thermometer reads temp.
does this make sense? it is vital to have the UTH controlled by a themoSTAT.
