*Auto duty, auto backup, memory function when cut off electric.
*Fresh air auto control, energy saving.
*Factory trial run function, save testing time for factory when there is a large quantity.
*Probe fault protection; compressor on delay function;
*Compressor pressure high or pressure low protection; Smoke alarm;
*Phase wrong and phase lose protection ; exhaust temp high / low protection;
*Intelligence ambient temp control, make the ambient temp at a balance status;
*Strong stability, 0.15-80MHz interference rejection, 4KV high voltage and surge resistance
*SMT technology, 48 hrs burn-in test for ensuring quality
*MODBUS-RTU RS485 Widely-used communication protocol, up to 1km max distance (Gateway Free);
*PCB Surface painted with CRC, avoid leakage, short circuit, and erosion from acid/ alkali/ alcohol/ humidity/salt spray;
*Featured with tension and torsion resistance probe, long working life
*Wide voltage range, avoid misoperation caused by voltage fluctuation
*Control logic implemented on the control board. Continue working even HMI has fault.
