Elitech EK-3020 is a temperature controller with touch screen buttons. It is suitable for temperature control of cooling and defrosting output. With temperature measurement, temperature display, temperature control, temperature correction, forced defrosting, temperature overrun alarm and sensor fault alarm function. One-touch restoration of original setting values for easy re-adjustment of parameters.

It has the function of defrosting cycle power-off memory, even if the equipment is unexpectedly powered off, the defrosting can still be started in time to ensure the normal operation and cooling efficiency of the unit.

Due to its touch buttons, Elitech equipped the EK series with a key lock function to avoid accidental touches that may cause the parameters to change. The touch button adopts high-precision digital capacitance measurement technology, which can avoid various interferences such as water droplets; compared with mechanical buttons, there is no mechanical action, long life, and stable performance.

Elitech EK-3020 temperature controller is suitable for temperature control of medium and low-temperature cold storage, freezer, operating console and other refrigeration equipment.

One-way sensor input: temperature probe sensor.
Two-way control output: Refrigeration and defrost.
