Reading a stealth temp control

i got so sick of that with all of the heaters ive tried in the past.
throw that thing away and get a rena smartheater. best heaters ive found, set them on 80, put them in the tank, and thats it. never have to mess with them or adjusted them, EVER. tanks stay between 80.1 and 8.9 all the time (digital thermometers).
not to mention, it can replace your filter intake tube. if you have an aqua clear or something similar, it will usually slide right over it snugly.

Go digital and go rena! The dials are dumb for the very reason you've pointed out. It's probably not what you wanted to hear from anybody but it will be worth it. Use the stealth in a different "not so important" tank or donate it to a school. Not mine though.

A black bar before the value 76 would be 75, and the one after, 77. If the numbers printed are in increments of 5, then the black bars indicate values half way between the printed values. Doing it any other way would require font sizes so small that you wouldn't be able to read them. Make sense?
If you are seeing a temperature swing of 4 degrees ( + or - 2 degrees from the set point) you needn't worry. Heaters as a rule are designed to operate this way particularly those that have bimetal thermostats. Once turned on, it will continue heating until it reaches a temperature 2 degrees above the setpoint and then shut off. It will then not turn on again until the temperature drops 2 degrees below the setpoint.
They are built this way to prevent early failure caused by a high number of switching oprations, and reduce the amount of contact bounce or 'buzzing' that we sometimes hear when a heater is turning on.
Tighter temperature control requires application of solid state relays, thermocouples, and a PID controller.
I am impressed with the accuracy of my Ebo Jagers. the number on the dial actually matches up with my tank temp! and it has an indicator light to boot
Wow thanks for all the input guys. I was planning on buyin another stealth today for my new 20 gallon. Maybe ill buy a smart heater for the 55 and put my 200 watt stealth on my 20 gallon .
And thank you potts050 for the post I really appreciate you putting that down for me buddy. I know that took a few minutes but it helped me understand this damn dial.
