Hi, I’m Ryan Kliethermes, the product manager for KE2 Therm Solutions.
We are often asked how to setup the KE2 Evaporator Efficiency for a freezer, so in this video I’m going to walk you through the process of setting the controller for use on a freezer.

Because our default settings are configured for freezer applications, a -10 degree Fahrenheit room temperature, electric defrost and mechanical expansion valve, setup is simply a matter of confirming, or modifying these three setpoints from the intro mode, and enabling or disabling SmartAccess.

Okay, so you’ve already wired the controller, now the controller will prompt you for the room temperature.

As I mentioned, the default value is -10.0 degrees Fahrenheit, and the rightmost 0 will be flashing. If you want the room temperature warmer, press the up arrow, and if you want it colder, press the down arrow. Once you have the room temp where you want it, press and hold the enter button for three seconds.
Next the controller will then display the words “Defrost Type” a couple times, and then display “Electric” for electric defrost. You can change this value by pressing the up and down arrow, or if Electric is correct, press and hold the enter button for three seconds.
The controller will now ask for the expansion valve type, and display “Mechanical” as the default. If you have a mechanical valve, then press and hold enter for three seconds. If you have an electric expansion valve, then use the up and down arrow to get to the correct valve. Then press and hold enter for three seconds. If you use an electric valve, you will then have to verify the refrigerant type.
The last question to answer is whether or not you want SmartAccess disabled or enabled. Make your selection by using the up or down arrow, and then press and hold enter for three seconds.

Your controller is now in charge of your refrigeration system.
The adaptive defrost algorithm means that no defrost schedule setup is needed. There are a number of other parameters that can be adjusted from the generally accepted industry defaults.
I hope this video will help you get your controller, up and running quickly, and help make you more comfortable with navigating the controller from the front panel.

We are happy to provide answers from refrigeration engineers and OEM manufacturers, like Kolpak, International Cold Storage, Crown Tonka, Thermalrite and many more.
