Quick Summary
The Inkbird ITC-306T is an aquarium heater thermostat temperature controller for managing tank heating with dual heating control and a dual time cycle setting. It uses a submersible probe and includes temperature calibration, along with over-temperature and sensor fault alarm functions.
The stated temperature measuring range is -50~99 °C / -58~210 °F, and the maximum total output load is 2200 W at 220 V or 2400 W at 240 V. It is stated to support two heaters working at the same time.
Key Details

What to Compare Before Buying
- Voltage and load: The stated total output load changes between 220 V and 240 V. Check the supply voltage and the combined heater load before choosing an offer.
- Heating setup: This model supports two heaters working at the same time. Compare that with the number of heaters you want to control.
- Temperature control: The controller includes temperature calibration and dual time cycle setting. Check whether those functions match the way you want to manage tank temperature across the day.
- Probe use: The probe is submersible. Make sure that suits your aquarium setup and where you plan to place it.
Compatibility, Size and Fit
This controller is aimed at aquarium heating setups and is stated to work with fish tanks, pond heaters, tropical shrimp and turtle setups, greenhouse use and reptile vivariums such as snake and frog enclosures. The key fit check is the heating load and voltage, together with whether you need one heater or two.
Because the controller works with a submersible probe, the probe placement also matters. Check that the probe location suits the tank or enclosure layout before ordering.
Using It in Practice
The dual time cycle setting lets the controller use two different temperature bands over a 24 hour period. That is useful when you want a daytime and night-time heating pattern rather than one fixed setting.
The probe and alarm functions make the controller more relevant where consistent temperature control matters, but the exact heater setup still needs to match the stated load limit and voltage.
Before You Decide
Confirm that the ITC-306T is the exact model you need, then check the supply voltage, the combined heater load and whether you want to run one heater or two. If the probe position matters in your setup, make sure the submersible probe suits the tank or enclosure layout before you choose an offer.
