Elitech EK-3030E is a temperature controller with touch screen buttons. It is suitable for temperature control of refrigeration, defrosting and fan 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.

Compare to the EK-3030 temperature controller, EK-3030E Add 485 communication interface, the communication protocol adopts MODBUS. EK-3030E can be connected to the network as a control terminal device and has the function of remote monitoring and setting.

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.

Elitech EK-3030E temperature controller is suitable for temperature control of medium and low-temperature cold storage, freezer, operating console and other refrigeration equipment.

Two-way sensor inputs: temperature probe sensor and defrost probe sensor.
Two-way digital signal input: DI1, DI2
Three-way control outputs: refrigeration, defrosting and fan equipment.
