In my opinion the original ITC-308 was and is a game changer as far as homebrew temp controllers.  In comparison to available controllers available at the time the ITC-308 was released, it offered loads more features, including dual stage control, for a fraction of the price.  Game changer!  The addition of Wi-Fi control and monitoring to this great controller has made a great temp controller even better.  Check out our Hands on Review of the ITC-308.  That includes a section on the WiFi version.

Hands on Review: Inkbird C909 1,500 Watt Digital Temperature Controller

I’ve used an Inkbird Dual Stage Temperature Controller, model ITC-308 for years on my fermentation deep freeze and have loved it.  Check out my Hands on Review of that game-changing controller.

As part of a move and a resulting kegerator update and refresh, I decided to replace my old temp controller (from a now defunct manufacturer) and ended up settling on Inkbird’s single stage C909.  That model was attractive because I’ve been extremely happy with Inkbird’s gear and I really like the fact that it plugs directly into an AC socket.  The wall I now have my kegerator on has no studs to mount a controller.  Because this is an Outlet Thermostat, the C909 solves that.

Note that the C909 is a swiss army knife of sorts, it has several different modes of operation including – timer, temperature controller, humidity sensor and cooking thermometer.  The C909 recognizes which probe type is plugged in (defaults to timer mode with no probe) and automatically switches to that mode.  For this review, I will be discussing the temperature control mode only.

Why Use an Over-Riding Temperature Controller?

Refrigerators and chest freezers are designed to do particular tasks.  As homebrewers, fermenters and home kegerator owners, we are asking these devices to do slightly different things and operate in different temperature ranges than built in thermostats allow for.  Over-riding temp controllers cycle power on and off to give you more fine tuned control.  This allows you to convert a chest freezer into a kegerator or fermentation chamber.

Hands On Review: Inkbird ITC-308 Dual Stage Temperature Controller +WiFi Version


Inkbird’s ITC-308 Digital Dual Stage Temperature Controller is a dual stage, pre-wired Digital Temperature Controller

It comes in the original version as well as an updated Wi-Fi enabled model.  This review covers both editions of this controller.

Why a Temp Controller?

Temperature controllers, sometimes referred to as over-riding thermostats, can control devices like refrigerators, freezers and fermentation heating devices to provide a consistent temperature for your kegerator, fermentation chamber or brew system. They do this by monitoring the temperature and cycling on and off the device in question. Generally, you will set the device to full cooling or heating power and the temperature controller takes over from there.

Dual vs Single Stage

Dual stage means that the ITC-308 can control both a heating and cooling device.  Alternatively, it can control a heating or a cooling device.  This controller displays in Fahrenheit and Centigrade.  Dual Display shows both measured and set temperature.
