What is the Aquarium Heater Controller & Why you Need it?

Aquarium heater controllers are indeed a life-saving device. This device and aquarium heater goes hand in hand. It is very important to have a heater controller in your aquarium along with the heater.

Nothing is flawless in this world, the same goes with an aquarium heater. Sometimes they can’t sense the temperature of the water and hence are unable to regulate the water temperature. Here comes the role of the heater controller. The heater controller will sense the water temperature and will control the heater to regulate the water temperature accordingly. Otherwise, you will get yourself ready for the biggest nightmare in the face of dead fishes.

In a nutshell, these heater controllers are really very useful when an aquarium heater gets malfunctioned. That is the reason they are used in aquarium tanks.

Parts of the Heater temperature controller

Let’s talk about its operation! It has three important parts that are Controller, Socket, and Temperature sensor Probe.

1. Controller

One of the most important parts. You can call it the brain of the heater controller. It has an LCD display that lets you set your desired temperature. The controller ensures either the water in the tank is of appropriate temperature or not.

2. Socket

The socket is a point where you will connect your heater. It has to be there otherwise you will not find any place to plug in your heater.

3. Temperature sensor probe

It’s last but not least is the temperature sensor probe. It will sit inside the water tank and will tell you about the temperature of the water.

How Aquarium Heater Controller Works?

These three parts work in collaboration to set the desired temperature tank. You just have to set your desired temperature on the controller LCD screen. Once you are done with it, the controller with the help of its temperature sensor probe, will read the inside temperature of the tank and compare it with your pre-set temperature.

If the controller finds the tank temperature is lower than your desired temperature, it will start its working by turning on the heater.

But once the temperature of the tank reaches the desired point, it will shut off the heater, until the temperature drops again.

Wow! Quite simple and impressive working.
