JBJ True Temp Digital Controller w/ Heater Information

Part #: T3-150

JBJ introduces the TRUE TEMP digital heater controller and titanium heating system. The TRUE TEMP is the most complete heating system to date with the most advanced features that set it apart as the leading heater for professional hobbyists.

Our digital microprocessor boasts amazing +/- 0.5 F accuracy, a calibration setting, indestructible titanium heating element with thermal shut off, smart memory chip, LED heating indicator, safety guard, remote temperature probe, and a large constant LED display of the current temperature.

Maintaining the correct temperature for tropical fish may be the single most important factor for a successful aquarium. Since fish do not have the ability to regulate their own body temperature, it is crucial that we can provide consistent water temperatures with minimal fluctuations.

Majority of fish cannot cope with stress from constant temperature fluctuations, which leads to a compromised immune system. This increases the probability of avoidable diseases, parasites, and bacterial infections.


Don’t be fooled, some controllers still incorporate analog dials and knobs without the precision accuracy of TRUE digital controllers. Our advanced microprocessor constantly reads and displays the correct temperature to a tenth of a degree with a large LED display. Easy push buttons make setting your desired temperature simple and easy.

The perfect submersible element for fresh or saltwater aquaria. Virtually indestructible with the benefits of fast heat transfer without any corrosion. Integrated thermal shut off and out of water safety mechanism.

Most heaters have an integrated temperature probe within the same heating element. This can lead to false readings and premature ON/OFF cycles. The TRUE TEMP digital controller is equipped with a remote quick disconnect temperature probe that can be placed up to 5 feet away from the heating element for a comprehensive temperature measurement of the total volume of water. Quick disconnect temperature probe grants easy replacement without the need to replace the entire controller in the event it fails.

All titanium heating elements are securely placed inside our safety guards that protect you and your livestock from the heating core. Our flow thru design grants continuous water contact without interruption.

Have you ever noticed that majority of heaters cannot be calibrated. Often times, errors do occur during the calibration process. The ability to cross reference ensures your temperature is accurate and always correct.

An integrated smart memory chip will restore the previous temperature set point and calibration to the last stored setting once the power returns after a failure. This alleviates having to manually reset settings forever.

Great Heating System Product Review by Fish Lover's of N.E. PA (Posted on 2/26/14)

Comments: My husband has 4 fish tanks - the biggest being 175 gallons. It's been very difficult keeping it heated properly. The JBJ True Temp Heating System has been an excellent answer to the problem! Instead of buying many smaller, breakable heating sources he decided to invest in this heating sytem - all in one - and easy to manage. Thanks! Sincerely,Fish Lover's of N.E. PA

Controller failed twice in 5mo Product Review by NATHAN SMITH (Posted on 2/26/14)

Comments: I've been keeping tanks since 2008 and have heaters fail in the past but never like this. I relieved this product for Christmas, but when I installed it the controller would not power on. JBJ replaced the unit, but 5 months later it failed again and this time cooked my established reef at 97.5 degrees. I contacted the company and they will only replace the controller again, not any of the livestock that I've kept for the last 8 years. NEVER trust this controller, only use the heater if it's attached to a controller like a reefkeeper or equivalent

Very Poor Long Term Product Review by PDCCO (Posted on 2/26/14)

Comments: I have had multiple units fail after around six months of use. I would recommend everyone avoid this product. I in each case the controller would not register the correct tempature (usually the controller would report a temp 10 to 15 degrees too high); Controller reported water temp at 83, actuall water temp was 71. If you are currently using this product please verify your water temp with an accurate thermometer!
