Transcription

1 0Hz Heat Pump Inverter Single Phase.kW to 8.0kW turn to the experts Product Data FEATURES AND BENEFITS AVAILABLE SIZES: Nominal capacity are available from.kw through 8.0kW to meet the needs of residential applications. CERTIFICATION: All models are registered with MEPS. ELECTRICAL RANGE Units offered in single phase 0V ~ 40V. ENVIRONMENTAL REFRIGERANT The uses R410a, the environmentally sound refrigerant that provides home owners with additional peace of mind because R410a has zero ozone--depletion potential. UNIT DESIGN: The copper tube(i-g), coated fin, enhanced sine wave, aluminum fin coil is designed for optimum heat transfer and corrosion protection. The sereis 0 Hz Split--System of inverter Heat Pumps are designed for quiet, reliable heating during the winter and cooling during the summer. These heat pump systems provide economy of operation through energy conservation when used with components designated by the manufacturer. The series recovers heat for indoor comfort from outdoor air during the heating season and, by automatically reversing the refrigerant system, remove indoor heat and excess humidity during the cooling season. SOUND SHIELD All ODU have compressor sound SHIELD for noise attenuation. OPERATING RANGE: Minimum outdoor operating ambient in cooling mode is -10 C, and maximum is 48 C. Minimum outdoor operating range for heating mode is -1 C, maximum is 4 C. HIDDEN DISPLAY The lights can be turned off by remote controller when the unit is running. -WAY DRAINAGE CONNECTION Both left and right sides of indoor unit are possible for drainage hose connection, easy for installation. LOUVER POSITION MEMORY When starting the unit again after shutting down, its louver will restore to the angle originally set by the user. 1

2 FEATURES AND BENEFITS ( CONT.) REFRIGERANT LEAKAGE DETECT (1)Only be active in cooling mode. ()If the refrigerant have leakage, the display area will show EC and AC will turn off. (3)The refrigerant leakage detect function can better prevent the compressor being damaged by refrigerant leakage or compressor overload. 8 HEATING (1)In heating operation, the preset temperature of the air conditioner can be as lower as 8, which keeps the room temperature steady at 8 and prevents household things freezing when the house is unoccupied for a long time in severe cold weather. ()This function can be memorized if the power fails. QUIET DESIGN Select SILENCE on remote controller to enter silence operation.(press the button for second). Indoor fan will run at super breeze, which can keep indoor in a very low noise level, make a comfortable feeling for sleep. FOLLOW ME ( 1) With this function, the room temperature sensor built in remote controller is activated and replaces the one in indoor unit. Then the air conditioner will regulate the room temperature based on the temperature around the remote controller, just like the air conditioner is following the user. ()Pressing the Follow me button on remote controller to active this function. Then the remote controller will send PCB the signal every three minutes. If the PCB doesn t receive the signal for 7 minutes or pressing Follow me button again, the follow me function will terminate. LOW AMBIENT COOLING The outdoor fan speed can be changed according to the condenser temperature and the AC can run smoothly under the temperature as low as -10.

18 TROUBLESHOOTING For ease of service, the systems are equipped with diagnostic code display LEDs on both the indoor and outdoor units. The outdoor diagnostic display is two LEDs (Red and Green) on the outdoor unit board and is limited to very few errors. The indoor diagnostic display is a combination of flashing LEDs on the display panel or the front of the unit. If possible, always check the diagnostic codes displayed on the indoor unit first. The diagnostic codes displayed in the indoor and outdoor units are listed in the tables below. Operation lamp Timer lamp Display LED STATUS 1 time X E0 Indoor unit EEPROM parameter error times X E1 Indoor / outdoor units communication error 3times X E Zero crossing signal detection error 4 times X E3 Indoor fan speed has been out of control times X E4 6times X E Open circuit or short circuit of indoor room temperature T1 sensor Open circuit or short circuit of evaporator coil temperature T sensor 7 times X EC Refrigerant Leakage Detection 1time O E0 Current overload protection times O F1 Open circuit or short circuit of outdoor ambient T4 temperature sensor 3times O F Open circuit or short circuit of condenser coil temperature T3 sensor 4times O F3 Open circuit or short circuit of compressor discharge T temperature sensor times O F4 Outdoor unit EEPROM parameter error 6 times O F Outdoor fan speed has been out of control 1times P0 IPM malfunction or IGBT over-strong current protection times P1 Over voltage or over low voltage protection 3times P High temperature protection of compressor top diagnosis and solution times P4 Inverter compressor drive error = Flashing, X = Off O = Light For additional diagnostic information, refer to the Service Manual 18
