Westinghouse Ducted Split Inverter T1 Cooling & Heating 48000 BTU Capacity (WD48PNCG31UE)
SPECIFICATION
Higher Efficiency & More Energy Saving
Through setting temperature lower limit in cooling or drying mode, and setting temperature upper limit in heating mode, the system is able to operate in a smaller temperature range so as to achieve energy saving. Besides, the unit has got the following energy-saving technologies
The indoor unit and outdoor unit adopt high-efficiency DC brushless motor. The efficiency of such motor will be improved by over 30% compared with conventional AC motor. Therefore, the energy efficiency of the entire unit will be improved by 15% under low frequency operation.
The unit adopts high-efficiency DC inverter compressor self-developed by Westinghouse. The high-efficiency DC inverter compressor self-developed by Westinghouse adopts 180° sine wave space-vector inverter driving technology, so as to realize reliable and stable operation in the frequency as low as 10Hz.
180° Sine Wave Technology
Westinghouse advanced DC inverter 180º vector control ensures the stable operation for compressor, energy-saving up to 20% per year (compared with the common air conditioner).
Precise Temperature Control Technology
Westinghouse intelligent inverter control delivers the required capacity according to the load variation from 10% to 120% and maintains the room temperature within 1℃ of set temperature.
Auto Clean (X-FAN)
Do you know that water in IDU will give birth to bacteria which will affect human health? It will wipe out water, caring for your health!
Building Management System Interface (MODBUS Protocol) and Long-distance Monitoring
The unit is with build-in MODBUS interface. If the unit is to be connected with the building management system, please consult with Westinghouse for the development of MODBUS protocol. In this case, the unit operation information will be sent to the building management system in order to control and monitor the unit.
Centralized Control Function
The indoor unit is equipped with the interface that can be connected with Westinghouse smart zone controller, in order to realize central control of 16 units in maximum without connecting wired controller. It can control the on/off, mode, fan speed, temperature setting and timer of a single unit or a group of units.
Malfunction Relay Output Function
The unit can be connected with the warning apparatus. When a certain unit stops for malfunction, the warning apparatus will give out warning to remind the administrator for maintenance.
High Ceiling Applications
The 24K~48K units are applicable to the height below 4.5m Units below 24K are applicable to the height below 3m. 
Intelligent Defrosting
Did you ever feel annoyed when the air conditioner stopped heating because of defrosting? This problem is already resolved by Westinghouse. Unit will only start defrosting when it’s necessary. More energy-saving and comfortable to you.
