*Heating or cooling modes selectable
*Fresh air valve control, inlet fresh air, energy saving
*If the room CO2 density larger than the setting value, the fresh air valve will on in order to improve air quality.
*Day or Night modes selectable, energy saving
*Fresh air E-heater to auxiliary heating, avoid temperature unstable.
*Trial run function; Memory function
*Directly control of the condenser fan, free of external pressure switch.
*Support auto restart function, terminal chains control.
*Support timer on /off function, password protection function.
*Compressor pressure load protection and compressor balance spoilage function
*Compressor motor protection and high and low pressure protection.
*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.
