Technical Information

6. Electric Heating Function of Chassis
(1) When Toutdoor amb.≤0 , the electric heating of chassis will operate;
(2) When Toutdoor amb.>2 , the electric heating of chassis will stop operation;
(3)When 0 <Toutdoor amb.≤2 , the electric heating of chassis will keep original status.
7. Electric Heating Function of Compressor
(1) When Toutdoor amb.≤≤-5 , compressor stops operation, while the electric heating of compressor starts operation;
(2) When Toutdoor amb.>-2 , the electric heating of compressor stops operation;
(3) When -5 <Toutdoor amb.≤-2 , the electric heating of compressor will keep original status.
