Description

The Johnson digital temperature controller is used to control the temperature of a refrigerator, or similar cooling or heating device. Enter your desired temperature, called set point, and how tightly you want your temperature maintained, called differential, and let the controller do the rest.

Ranco Vrs. Johnson 
This Johnson digital temperature controller is very similar to our popular Ranco brand controller (FE610) in application and appearance. The advantage of the Ranco is being able to switch between cooling and and heating from the digital interface, while with the Johnson you have to take the cover off and physically remove a jumper. The advantage of the Johnson is the very attractive price.

For technical aficionados the Johnson does have a feature called Anti-Short Cycle Delay. Cycling is the rapid turning off and on of an electrical device. Over time cycling can harm your appliance. The Johnson controller allows you to set a time interval, in minutes, that keeps the controller from turning on right after it shuts off no matter what the temperature reading is. This can be very useful when you are using a 1 degree of differential setting for tight control but want your compressor or power supply to have a minimum time period of rest before it turns back on. Temperature Range of -40 to 212F.

To make a chest freezer into a fridge for a mobile cafe. This conversion is more space saving than a regular fridge.

I read you no longer have to remove a jumper to change from heating to cooling. It can be done from digital interface. Is this true?
Kenneth Kahle on Jan 20, 2018
BEST ANSWER: Yes it’s true. But remember you can only monitor one or the other. In my case I have two units. One that’s controls heat and a separate unit that controls cold temperatures. I also thought that the instructions were a bit more technical and hard to follow unless you set up refrigeration systems for a living. It took me a couple of days to figure them out. My best tip and the one I missed at first (being a guy) is there is a picture of a flame or ice to help you know whether you are controlling hot or cold temperatures.

Works great
I use one on a freezer for cold stabilization, and one on a fridge for cold fermentation. It is fairly easy to set up, keeps cool at a consistent temperature, and is well manufactured. Recommended!

Missing part
Seems solid but it’s missing the jumper inside which prevents me from changing the settings. The settings are locked without the jumper. I will re-review after getting a 30 cent jumper from here or the manufacturer. Luckily I had a backup controller for my keeper!

Works great.
Works great for fermentation temp control, keeps the temp within a degree or less of the setpoint using a thermowell on the fermenter and an older Kenmore fridge. Super easy to use and install.
