Function PACD011001C2
54 Function Urban Multi “MX1, ME1 Series” Using R-22
1.21 Oil Temperature Sensor (8 and 10 Hp only)
1.21.1 Prevention of Wetness during Heating
‹
Wet operation is prevented by modification of super heating (SH) by oil temperature sensor (R5T).
(Low equivalent pressure = Te)
1.21.2 Prevention of Oil Dilution during Defrost
‹
The unit controls upper limit frequency of the compressor and is designed to prevent oil from being
diluted while defrosting by means of an oil temperature sensor.
‹
Startup subsequent to defrosting is improved by the oil temperature sensor.
