• Sleep Mode
  The function enables the air conditioner to automatically increase cooling or decrease heating 1°C per hour for the first two hours, then holds steady for the next 5 hours, after that it will switch off. This function maintains both energy savings and comfort at night.
• Temperature Compensation
  Temperature compensation function eliminates the difference in temperature between the floor and ceiling by mixing the different layers of air. Consequently, the time for cooling the room is reduced, and a cold offset rising stream of warm air by stirring.
• 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.
• Emergency start
• 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 heating operation even when the outdoor ambient temperature is down to -13°F.
• 1W Standby 
  Intelligent on-off technology enables Pioneer products automatically  enter energy-saving mode when standby, cut energy consumption from normal 5W to 1W or 0.5W per hour which counts 80%~90% of saving.
• 2-way Draining 
  Both left and right sides of the indoor unit are possible for outstretch of connective piping and drainage hose for easy installation.
• Follow Me (Remote Thermostat) 
  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.
• 46°F Heating
  In heating operation, the preset temperature of the air conditioner can be as low as 46°F, which keeps the room temperature steady at 46°F and prevents the house from freezing when it is unoccupied for a long time in severe cold weather.
• Chassis Heating Belt
  Heating belt is fitted on the base plate of the outdoor unit to prevent defrosting water accumulation, which improves heat transfer efficiency.
