Features The main features of this series are as follows: 1) No Outdoor Unit: The evaporator & condenser is assembled in a single compact casing. Thus, it eliminates a bunch of additional work to install a separate outdoor unit. 2) Compact & Low Height Profile: MWH-C is a packaged unit consisting of compressor, coil, tube in tube heat exchanger, expansion device and forward curved confrigual fan. All units are designed with low height profile, ranging from 373mm (2.5kW) to maximum 500mm (20kW). 3) Double Isolation Panel: Double layer of innovative basepan design effectively reduce the compressors vibration. 4) Precharged Refrigerant: All MWH-C models come with factory precharged R22 refrigerant. 5) Partial Lonely Capability: For model MWH028/030/040 C/CR, which are having two compressors are able to be controlled at either 50℅ or 100℅ depending on the load requirement. 6) Microprocessor Control: All models are equipped with IC remote controller with the following features:
- 7 days programmable timer
- Auto random restart
- Error self diagnostic
- Competible with MC303 central controller
- Energy saving function
7) LCD Wired Controller as Standard: All models come with a LCD wired handset. 8) Safety Protection:
- High pressure switch
- Low pressure switch
- Compressor overload protection
- Fan motor overload protection
- Water temperature protection
9) Accessories: Spring Isolator kit is offered as an option. This product are applicable for residence, shopping market, hotel and industry area.
