## Overview

The JBJ Lighting JB1235 True Temp Digital Heater Controller is a state-of-the-art temperature management solution designed for precision and convenience. With its advanced microprocessor calibration, remote probe, and impressive 1000-watt capacity, this controller ensures your space maintains the perfect temperature effortlessly.

## Description

The true temp digital heater controller is one of the most accurate and precise controller in the aquarium industry. The all new true temp boasts amazing +/- 0.5 F accuracy, a calibrating setting, smart memory chip, led heating indicator, 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 provide consistent water temperatures with minimal fluctuations. Majority of fish cannot cope with the stress from constant temperature fluctuations, which leads to a compromised immune system. This increases the probability of avoidable diseases, parasites, and bacterial infections. Let the true temp digital heater controller help you keep a nice and stable environment for your wet pets!.

## Features

- All digital temperature controller with advanced microprocessor
- Calibration feature to allow for adjustments in temperature differentials
- Remote probe with five (5) feet cord for easy placement of main unit
- Plus/Minus 0.5 Degree f for extreme accuracy temperature reading
- Up to 1000 watt capacity for heater

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Just what I wanted.
  

*by M***K on Reviewed in the United States on April 29, 2015*

Don't spend very much time looking at others that can't be calibrated. It is easy to use and can be calibrated...but the same product is for sale at $20.00 cheaper and free shipping.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Works great for my salt water tank
  

*by M***H on Reviewed in the United States on October 2, 2021*

Easy to install. Lasted about 5 years before needed replacement.

### ⭐⭐ 2.0 out of 5 stars







  
  
    Not reliable and no customer support
  

*by M***R on Reviewed in the United States on March 1, 2022*

I currently run seven of these (one shipped with out the temperature sensor, but the seller sent me one), but I'm considering taking them all out of service, because I have to keep a close watch on them after this...I have one that began to show a "HI" error reading which meant that the temperature in the aquarium exceeded 99F. Two different thermometers in the water proved that the water temperature was 78F.  I unplugged the controller and plugged the heater directly into the outlet, because the controller stopped the heater from working once the "HI" error began.  Then, after leaving the controller unplugged for a day, I tried hooking it back up. I noted that the temperature reading was erratic, changing up and down until it finally read "HI" again.  So, I unplugged it.  I emailed the company - no response.  I used their online messaging page - no response. I've called several times - got voicemail.Since most good heaters include a hi temperature cut-off, this product is redundant as well as long as your heater has a high cut-off. And, if the controller stops working then the heater stops heating as well.So far the others I have are still working, but I'm going to keep a close watch on them.
