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

Updated: February 17, 2025

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

The ITC-308 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.

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 ITC-308 Dual Stage Temperature Controller

Updated: February 4, 2025

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

The ITC-308 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.

This controller can control both a heating and cooling device.  Alternatively, it can control a heating or a cooling device.

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.

As of this update, this great controller is on sale for $49.99.

Johnson Controls Analog Temp Controller – $84.99, Save $20 + free shipping, limited availability

johnson analog temp controller

Analog Temperature Controller via MoreBeer

More Info

From the product description, check product page for current description, price and availability:

Use this analog unit to control the temperature of a refrigerator, freezer, or air conditioner. It enables you to ferment and store beer at correct temperatures when the ambient room temperature is too warm.

Your electrical cooling device plugs into this unit which plugs into the outlet. A remote sensor connected by a small capillary tube monitors temperatures. If the temperature rises above your set point, the cooling device is turned on.

The unit features a 4 degree swing to help extend the life of the cooling unit’s compressor. For example, if you had it set at 68 degrees, it would turn on at 68 degrees and go to 64 degrees before turning off. The unit has the potential to regulate temperature from 20 to 80 degrees Fahrenheit.

The sensor tube can be inserted into a refrigerator or freezer, and still allows the door gasket to seal tight. Temperature Range of 20 to 80F.

This Johnson unit can handle 15 amps or 1725 watts at 115 volts AC.

 

The only reason I can think of to go this route vs an Inkbird digital is needing a beefier commercial quality type of unit.
