Inkbird WIFI ITC-308 Dual Temperature Controller

Inkbird WIFI ITC-308 temperature controller

The Inkbird WIFI ITC-308 is a fermentation temperature controller with one temperature probe and dual relay outputs, so it controls both cooling and heating automatically. It keeps the right fermentation temperature and lets you adjust it during fermentation, for example for a diacetyl rest and cold crash. With WIFI, you can monitor and adjust the fermentation temperature in the "Inkbird Pro" app wherever you are. Brewshop is the Norwegian importer of Inkbird.

How to use the Inkbird ITC-308

1. Attach the temperature probe to the outside of the fermenter with insulation tape, or place it in a thermowell.
2. Set the desired temperature.
3. Plug the heat source into "heating" and any cooling source, such as a fridge you ferment in, into "cooling".
4. The Inkbird then controls the surroundings based on the actual temperature of the beer.

A cool basement room and a panel heater will get you a long way. The app can also control several Inkbird controllers, which is handy if several units need to hold different temperatures.

Note: The probe is not waterproof. Do not place it directly in wort or water.

There is no jack connection for the Inkbird thermometer probe. If you want to use such a probe, you have to join the cables yourself.

Frequently asked questions about the Inkbird WIFI ITC-308

Can I use the Inkbird ITC-308 with an ordinary fridge?

Yes. Plug the fridge into "cooling" and a heat source, such as a heat mat, into "heating". The controller has compressor protection, so the fridge is not switched on and off too often.

Where should the temperature probe go?

Attach the probe to the outside of the fermenter under insulation tape, or place it in a thermowell. That way you measure the temperature of the beer itself rather than the surrounding air. The probe is not waterproof and should not sit directly in wort or water.

How much power can the controller handle?

Maximum output is 2200 W at 220 V, and both the cooling and heating relays are rated at 10 A.

Why does temperature control matter during fermentation?

Yeast generates heat during the most vigorous part of fermentation, and room temperature varies. Too high a temperature produces esters and fusel alcohols, while too low a temperature can lead to slow or incomplete fermentation. A stable temperature is what matters most.
