Elitech EK-3021 110V Temperature controller is a smart communication temperature controller, used for temperature control of cold storage and heating devices. It could be connected to the internet as control terminal and could control and set parameters remotely.
It has the function as below: measure, display and control temperature; temperature calibration; forced defrost; over temperature alarm and sensor failure alarm; one key recovery of the factory default value, parameters preset and one key recovery; key lock function, dual-way digital input, engineering password function.
Communication protocol adopts MODBUS protocol, TTL serial interface. Communication adapter card is optional to converse to 485 communication interface.
Dual-way sensor input: cabinet temperature sensor and defrost sensor. Two digital input.
Three way control output: Refrigeration/heating output, defrost and fan.
