Won Brothers D-58 LED Digital Display Temperature Controller Information

In this digital age of the Internet, fast computers, and handy gadgets, it only makes sense that even aquarium equipment gets an upgrade. Gone were the days when you had to squint at a thermometer to check the temperature of your water tank. Now, you can look at the digital display for the exact reading. Goodbye, guessing games!

The Won Brothers D-58 LED Digital Display Temperature Controller from Pet Store has a digital display from which you can easily read off the measurements. The readings of the built-in thermometer with a remote sensor are reliable and precise. That's great, but it's not the best thing about it.

The Won Brothers D-58 LED Digital Display Temperature Controller is not just a reader - it's also a regulator. You can use this device to bring your tank's temperature to an ideal level for your pet fish, corals and plants. Once at that level, this device keeps the measurement that way for as long as you have set it to. This eliminates frequent changes in the temperature, which is a good thing because frequent fluctuations can be a cause of stress for fish if not managed right away. Stress in fish leads to disease, something you want to avoid - and you can do that with the Won Brothers D-58 LED Digital Display Temperature Controller.

Comments: Worked fine for the first year held settings ok. Came home one day to find my tank looking strange I put my hand on the glass and it was hot to the touch! I look at the setting and it changed the set point to 110. I put a probe in and my water was at 88 so I pulled the canopy up and put some fans to cool it back down. I had some bleaching but everything did come back. DON’T BUY THIS IT WILL LET YOU DOWN.

Comments: The controller or sensor went haywire. I started getting tempature readings bouncing all over the place. The unit was great for about a year and a half and that was it. It's shot and ready for the garbage. Kind of expensive to last such a short time.

Comments: This unit kept me happy for about a year, then I looked at the teparature and it said it was 84 deg F (set for 75 deg F). I was concerned and noticed it claimed 91 deg F a few hours later. I began looking for a clogged pump or other problem and finally stuck a thermometer in the tank to find it at 76 deg F. The sensor has gone bad and cannot be replaced.

Comments: Have had this d58 controller for 1.5 years, and the temp sensor was off 1.5 degrees when I bought it. Still within there specs. Now the temp is 9 degrees off. Clean the probe, nothing helped. Unit is basically shot. Can't replace the probe.

Comments: Other than recieving it with the default temp setting of 96*f and being a whole 4*f off on the temp sensor, it seemed ok. Oh ya, is it normal for it to kick on the heater at almost a full degree below what you set it at and kick off almost a full degree above? We'll see if the second one works better.
