JBJ True Temp Digital Controller w/ Heater Information

Product Manuals & Documentation

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.

Comments: What a beautiful package. The heater works great just as advertised what makes it special for me is the magnet holders a breeze to set up. The controller makes the whole thing work set it and forget it.

Comments: I run a maintenance business and one of my clients had only had this heater for less than a year. Like others it totally failed and their reef crashed due to cold temperatures (hence why they called me to begin maintaining their aquarium). After getting the unit back to my shop the heater coil was completely broken and inoperable. So I decided to test the control unit. It would cut on and off at the specified temperature that I set on it, however after using a digital medical thermometer as well as a standard glass aquarium thermometer (both it and the medical digital were within .5°F of each other) the JBJ probe was reading 5 full degrees OFF to the high side. After reading through other reviews and my double, triple and quadruple checking of the control unit I would advise people to stay away from these units where stability matters.

Comments: I just upgraded my tank with new LEDs so out with the chiller. Which this meant I would need a heater. It was very easy to setup and after plugging it in I felt there was no way that temp could be right. I then went and bought an old school thermometer after leaving it in my tank for a few minutes I pulled it out and the temp was correct. I didn't have to calibrate it or anything. Well wrth the money.

Comments: I purchased the t3-800. I would not recommend it. Works great but! The controller connection is horrible. It constantly reads error at the slightest touch the connections aren't great. I took the heater rod and hooked it up to my controller instead. Worked great until yesterday. out of the blue it just crapped out. doesn't heat up at all. I bought the 800W even though my tank only needs about 500W so the heater doesn't have to work as hard. dead after 2 years. Better off sticking with a different less expensive titanium heater. and get two smaller ones instead of one big one.

Comments: I have had this heater for 3 months. I have to say that this heater works really well. I have the temp set to 77 and my tank stays in between 76 and 78. I have a second temp probe in the tank also and both probe read the temperature within .2 deg. The only thing that is upsetting is the JBJ didn't come with the magnets to attach just suction cups, but its not a deal breaker. I push in the suction cups every week when doing a water change no problems.

Comments: I have JBJ 28gal LED tank. I just got a Cbreeze fan to cool the tank during the hot summer days. This 150W heater unit works well with the Cbreeze fan, keeping my tank set at 79° - 80° temp during the day. I guess you can say they battle each other. I used to have a Marineland 100W Stealth pro heater but it seemed to have a 4°-5° temp change in the day time. I much prefer my new digital temp controller for the summer months. This is a much cheaper option than purchasing a water chiller. The only deal I did notice was that on a more regular basis I now have to regulate my water evaporation with the Cbreeze fan hooked up. LED's are the future for growth!

Comments: I've had this product (TT-800) for 1 year and 2 months. It had been working great, but as of three days ago the calibration temp has gone from my set temp of 77.7F to 92.4F for no reason. I've unplugged the unit and waited a day but no change, I have also tried to re-calibrate but the unit will not allow my to go any lower then 82.4F, and then it climbs back to 92.4. I have written the company and no response yet. At a 180.00 per unit I would recommend buying something that will last, I can not afford to buy one every year!
