Advanced Option (Upgraded EC Fan Coil Unit)
Symbolizing by outstanding energy-saving effect, the EC fan coil unit saves more than 30% energy compared with traditional fan coil units at the same motor speed. When the fan motor operates at mid or low speed, the effect of energy-saving is more remarkable.
Intelligent control by standard smart thermostat, with microprocessor technology, effectively permits to achieve the stepless speed variation with automatic adjustment of motor charges and electrical dampers by detecting the ambient temperature and the set-point, significantly improve energy-saving, comfort and reliability.
Traditional fan coil unit is normally operating in 3-variable-speed with a range of ±2oC for room temperature fluctuation. The upgraded EC fan coil unit features continuous automatic adjustment technology and stepless speed variation, which controls the room temperature fluctuation under ±0.5oC.
Operating with small vibration and any electromagnetic noise ensures a quiet operation and improves the tranquility and comfort for room environment.
Using electronic commutation module, reducing the abrasion of electrical components, makes EC fan coil units with higher quality and longer life than traditional AC motor fan coil units.
