About this product
The Inkbird ITC-306A is an aquarium thermostat rated at 1100 W for use with heaters only. It ships with two probes, which the directions say to place in the tank apart from each other, and two relays let it switch the plugged heater off when overheating is detected. The setpoint can be dialled anywhere from 20.0 to 35.0 °C (68.0 to 95.0 °F).

Power, relays and heating time
The controller is rated at 1100 W and carries two relays. Heating time is adjustable across 1 to 72 hours, so the timed window can be set to match the tank. If that time runs out before the water reaches the expected temperature, an alarm sounds.
What is in the box
The package holds the temperature controller itself along with two probes. The unit is rated at 1100 W and requires no assembly: it is plug and play, so the heater goes into the controller and the controller into the mains.

How the controller behaves in use
Two probes sit in the tank, spaced apart as the directions specify, and the controller compares the readings. Should the gap between the two exceed 3 °C (5 °F), an alarm goes off and the app sends a notification to the phone at the same time. Overheating triggers a different response: the plugged heater is turned off. The setpoint range runs from 20.0 to 35.0 °C (68.0 to 95.0 °F), while the probes themselves can register from −40 to 100 °C (−40 to 212 °F).
Checks before you buy
The thermostat is made for heaters only, and the manufacturer lists it as compatible with most kinds of heaters; check that your heater's wattage stays within the 1100 W rating. Two probes have to be placed in the tank at a distance from each other, which means the tank needs room for both. The alarm for a probe difference is fixed at 3 °C (5 °F), so readings that drift further apart than that will sound it. A setpoint can be entered only between 20.0 and 35.0 °C (68.0 to 95.0 °F).
