Frequently Asked Questions

How does aquarium temperature controller work?

In order to keep the temperature of the aquarium within a certain range, a heater or a refrigerator can be connected to the controller. The controller detects the ambient temperature and decides whether to turn on cooling or heating to achieve the set temperature.

Do I need an aquarium controller?

Of course, having a controller is an extra layer of protection for your aquarium. You can monitor the real-time aquarium temperature intuitively through the screen and receive an alarm when the temperature is abnormal. Take ITC-306A as an example. When the temperature is detected to be too high, it will immediately sound an alarm and automatically turn off the heating power.

Bryan L
ITC-306T- Wifi

I got the 306T. It works well once you can figure how to get it going. Make sure your wifi is strong where ever you have it.

Do the probes go inside the tank or on the outside pane of the tank

Where do the probes go ?
Inside the tank, or
Outside on the pane
Or, one inside one outside ?

Mark Dearborn
Great addition

Works as advertised. I was able to use an old heater that wouldn't shut off. Now, the controller shuts it off.

Brian Shrimpton
Excellent heater controller

I have been building my supply of these controllers. I now have 12 of them controlling tanks with high value fish such as imported Plecos, Discus and Rams.

Ethel Barone
Great multiuse device

Use it to incubate eggs, in the brooder, to germinate seeds, and control cooling or heating in greenhouse and chicken coops. The ad said it would have a wet and a dry probe, but it only came with the wet temp. probe (sensor).
