Inverter Products Control
Inverter Product Range Operating Mode • There are 5 operating modes: • Cool mode • When Tr ≥ Ts - 1.5°C -Comp, ID Fan and OD Fan ON • When Tr ≤ Ts - 2°C ** -Comp and OD Fan OFF, ID Fan remain ON • **When room temperature falling below compressor cut off • point even on the lowest operation frequency, compressor will • stop operates. Tr = Room Temperature Ts = Set Temperature Tr <= Ts - 2°C Comp will stop Lowest Freq Time
Inverter Product Range Operating Mode • There are 5 operating modes: • Heat mode • When Ts > Tr - 1.0°C -Comp, ID Fan and OD Fan ON • When Tr ≥ Ts + 1.5°C ** -Comp and OD Fan OFF, ID Fan remain at lowest speed if ID coil ≥ 27°C • **When room temperature rising above compressor cut off • point even on the lowest operation frequency, compressor will • stop operates. Tr = Room Temperature Ts = Set Temperature Tr - Ts ≥ 1.5°C Comp will stop Lowest Freq Time
Inverter Product Range Operating Mode • There are 5 operating modes: • Fan mode • Only High, Medium and Low fan speeds are allowed • Changing cool mode to fan mode; the compressor and outdoor fan will stop • Compressor will only ON if the minimum stop time is > 3 minutes if the user change back to cool mode
Inverter Product Range Operating Mode • There are 5 operating modes: • Auto mode (for single split) • Mode switching point: • Heating Cooling • Tr ≥ Ts + 2.5 • Cooling Heating • Tr ≤ Ts – 2.5 • During initial operation • Cooling operation: Tr > Ts • Heating operation: Tr < Ts Tr = Room Temperature Ts = Set Temperature
Inverter Product Range Operating Mode • There are 5 operating modes: • Auto mode (for multi split) • Without Priority Room Setting • If more than 1 indoor is operating, priority is given to the first unit that was turned on • If a unit is turned on later to the same operating mode as the first unit, the unit will operate as normal • If a unit that are turned on later to the different operating mode as the first unit, the units will enter Standby mode • With Priority Room Setting • Unit operation subjected to Priority Room operating mode
Inverter Product Range Communication • Communication between ID and OD • Master by outdoor unit • Indoor PCB transmits signal to outdoor PCB every 0.5s. Outdoor unit will response to indoor once the valid data is received • If the data communication line between indoor and outdoor disrupted for 15s continuously; Compressor will stop, OD fan will stop with fan delay timer. ID LED starts blinking error • If the communication resumes within 15s; error code will be cleared and compressor restarts after 3 minutes • If the communication does not resume after 15s; unit unable to restart and ID LED continues to blink
Inverter Product Range Minimum Run Control • To prevent frequent compressor ON/OFF and to allow pressure equalization • The compressor will be on 3 minutes stand-by after turning OFF before it is allowed to turn ON • OD fan delay by Off timer to improve pressure equalization and to prevent refrigerant from entering into evaporator
Inverter Product Range Auto Restart • Allow unit to automatically resume the same operating mode it was in before a power failure • Factory pre-set • Change over switching is only carried out during operation 4 Way Valve Control
Inverter Product Range Defrost Cycle
Inverter Product Range Defrost Cycle- A5LCY Series I • Condition for entering defrost • Compressor minimum run time of 6 minutes; OR • Compressor accumulated run time of 45 minutes if OD coil < 3C • When OD coil < 0C AND OD coil < OD air - 10C • Condition for terminating defrost • OD coil > 12C; OR • Total defrost timer of 650 seconds
Inverter Product Range Defrost Cycle- A5MSY • Condition for entering defrost • Compressor minimum run time of 6 minutes; OR • Compressor accumulated run time > 38 minutes • Based on OD coil temperature, output frequency & OD air temperature • Condition for terminating defrost • Minimum run time of 120 seconds; AND • Determine based on OD ambient, in the range of 4C ≤ OD coil ≤ 12C; OR • Totaldefrost timer of 650 seconds
Inverter Product Range Indoor coil freeze prevention • Outdoor fan control is carried out: • Only available in cooling mode • When the indoor coil temperature < 2°C, the compressor starts to drop the frequency • This protection will cut in when: • Indoor coil temperature < 0°C for more than 180s. • Compressor will stop, OD fan stop after 30s and indoor fan can only run at lowest fan speed • The unit can only be restarted after 3 minutes • When the indoor coil temperature > 13°C, the compressor frequency will be reset based on the OD ambient, room and set temperature
Inverter Products Troubleshooting Guidelines
Inverter Product Range Error Indication • From Indoor panel • When error occurs, indoor LED display will start • blinking continuously: Green light • The blinking pattern does not indicate of error details • The error details could be retrieved from handset
