Inkbird ITC-308-WIFI Temperature Controller

Inkbird ITC-308-WIFI Temperature Controller for Fermentation Control

The Inkbird ITC-308-WIFI temperature controller is a dual-stage digital controller for brewers who want steadier fermentation temperatures without constantly checking the fermenter. Plug your cooling device into the cooling outlet, plug a heater into the heating outlet, place the probe where it can read your fermentation temperature, and set your target range.

For homebrewing, this is one of the simplest upgrades for cleaner fermentation: use it with a fermentation chamber, refrigerator, freezer, heating wrap, BrewBelt, or similar temperature-control setup to help keep yeast inside its preferred range.

Why Brewers Use It

• Dual-stage control: Controls heating and cooling equipment from one controller.
• WiFi monitoring: Adjust settings, monitor temperature, and receive alerts through the INKBIRD app.
• Fermentation stability: Helps reduce temperature swings that can stress yeast and create off-flavors.
• Plug-and-play setup: No wiring required for normal use with compatible plug-in heating and cooling equipment.
• Useful beyond beer: Also works for wine, cider, mead, fermentation projects, and other temperature-control applications.

Important WiFi Note

The ITC-308-WIFI connects to 2.4 GHz WiFi networks only. It is not designed for 5 GHz-only WiFi networks. Check your router settings before setup if your network combines bands automatically.

How to Use It for Fermentation

• Cooling: Plug a refrigerator, freezer, or fermentation chamber cooling source into the cooling outlet.
• Heating: Plug a compatible heater, fermentation heating wrap, or BrewBelt fermenter heater into the heating outlet.
• Probe placement: For better beer-temperature tracking, place the probe against the fermenter under insulation or use a compatible thermowell setup.
• Set the differential: Use heating and cooling differentials to prevent short cycling and keep the system stable.
• Verify settings after power loss: Inkbird notes that settings are saved, but it is still smart to confirm your controller after any outage.

The controller switches power to connected heating or cooling equipment; it does not heat or cool by itself. If you are building a complete fermentation setup, browse our fermentation temperature control gear for heaters, thermowells, and related accessories.
