It is possible to connect from two to three indoor units.
The operating range of the system is 50-150% of the rated power of the outdoor unit;
Safe start and operation in the range from 96 V to 260 V;
Stable Frequency Control technology - smooth and stable operation at ultra-low frequencies (15 Hz);
Noise Analysis Technology - virtually silent operation of the indoor and outdoor units;
Wide temperature range of effective operation: from -15ºС for heating and up to +48ºС for cooling;
New generation automatic anti-icing system Intelligent Preheating . Contrary to the usual "timed" defrost scheme - an average of 10 minutes of defrost for 50 minutes of compressor operation, the defrost process is started only when there is a real need. This state of the art technology obviously reduces energy wastage for unnecessary defrost cycles;
Energy efficiency class "A".
