I have one in my 50 and the difference between thermometer and controller is way off....tank is 83 & controller is 89. I have 2 others still in the boxes which I'll be using in my 90 so I'll see what happens with them.
Has anyone use this tititatum digital heater with crontroller? I found that when I set my my desire temp the controller is usually 2-3 degrees higher than my what my other thermostats read. For example I set my temp to 82 degree but my glass thermostats reads at 84-85degree. Is there a way to calibrate it? For now I just lower the controller 2 degrees lower in order to get my thermostat to read 82. Just in case you ask I did test with more than one thermostats. Same result.

FYI I have two glass thermometers in a 100 gallon if you put then next to each other they will show two different readings.

I trust the thermometer. Out of all my heaters, I think all of them are off at least 1-2 degrees and a couple are off by more. I don't know which as I don't pay attention to the setting any more... I just adjust one direction or the other based on the thermometer.
Also, two thermometers might be off by a little if you have them on opposite sides of the tank and don't have the best circulation. This can also occur with your thermometer and controller being at different parts.
The differences are also based on technology and how well they're calibrated.

I have two of Jehmco's 500 watt Titanium Heater w/ ETCI Controllers on two tanks and both have been great. They are +/- a degree after a year plus, my experience has been that they are good quality controls.
Give John a call, always helpful!
