Front Desk Control
With a smart control board, Pioneer air conditioners can be turned on/off via long distance control signals.
46° F Heating
Refrigerant Leakage Detect
Indoor unit shows error code "EC" and stops automatically when refrigerant leakage is detected. This protects the compressor from high temperature damage due to refrigerant leakage.
Anti-cold Air Function
Indoor fan speed is regulated automatically from the lowest grade to the setting grade according to evaporator temperature when the unit just starts heating operation. This function can prevent cold air blowing out to avoid discomfort to the users.
Low Ambient Cooling
With built-in low ambient kit or special designed PCB, outdoor fan speeds can be changed automatically according to condensation temperature. The air conditioner can run cooling operation even when the outdoor ambient temperature is down to -15°C.
Temperature sensor built in the remote controller will sense it’s surrounding temperature. The unit will adjust the room temperature more accurately to give you comfort.
Compared with infrared remote controller, wired controller can be fixed on the wall and makes air conditioner control more convenient.
Remote in Engineer Mode
Central Control Management
