ESP+ Tutorial #6 – Changing Superheat Using On-Board Display

KeepRite Refrigeration ESP Tutorial 6

Installing an evaporator utilizing the ESP+ Intuitive Evaporator Control Technology is really quite simple. In most cases, it’s two pipes, two wires and you’re done. No interconnecting control wiring between the evaporator and the condensing unit is required.

Although the physical setup is very easy, sometimes you need a little help learning about the technological side of the setup including how to change superheat using the on-board display. But that’s what we’re here for!

To get started for this specific function you will need to access the Advanced Menu by pressing and holding the “Back” button until “tS” is displayed on the screen. Use the “” and “” arrows to navigate until “Stt” appears which stands for ‘superheat setpoint.’

Once you have “Stt” displayed, press “Enter” to toggle between the setpoint and its current value. Once the current value is displayed use the “” and “” arrows again to change the setting values.

The default setting is always 8 Fahrenheit and is adjustable up to a maximum of 30 Fahrenheit and a minimum of 5 Fahrenheit. To save the changed value, press “Enter” and hold for 3 seconds to confirm the setting. To exit this mode, simply press “Back”.

What does ESP+ control?

Along with superheat, the ESP+ also controls box temperature, defrost initiation, defrost termination, fan motors and defrost heater on electric defrost models. Not to mention users can access operating data directly from the system interface.
