Note: Wire check correction need to be carried out again if wiring is changed or corrected


A5MSY - Features Priority Room Setting

Allow user to set a particular room which takes precedence over the operation mode of other rooms

For example, if Room A is the priority room, when COOL mode is selected in Room A while Room B, C & D are operating in the following mode:

Operation mode in Room B, C & D

Status for Room B, C & D

COOL or DRY or FAN Current operation mode is maintained

HEATThe unit enters Standby Mode. Operation resumes when Room A unit stops operating.

AUTO

If the unit is set to COOL mode, operation continues.

If set to HEAT mode, it enters Standby Mode.

Operation resumes when Room A unit stops operating.

There are 5 operating modes:i. 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.

There are 5 operating modes:ii. 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.

There are 5 operating modes:iii.Fan mode

Only High, Medium and Low fan speeds are allowedChanging 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

Operating Mode


There are 5 operating modes:iv.Auto mode (for single split)

Tr ≤ Ts – 2.5

During initial operationCooling operation: Tr > TsHeating operation: Tr < Ts

Operating Mode



There are 5 operating modes:v. 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

Operating Mode


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

Communication


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 ONOD fan delay by Off timer to improve pressure

equalization and to prevent refrigerant from entering into evaporator

Minimum Run Control


Allow unit to automatically resume the same operating mode it was in before a power failure

temperature Condition for terminating defrost

Minimum run time of 120 seconds; ANDDetermine based on OD ambient, in the range of 4C ≤

OD coil ≤ 12C; ORTotal defrost timer of 650 seconds


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

Troubleshooting Guidelines


From Indoor panelWhen error occurs, indoor LED display will start blinking continuously: Green lightThe blinking pattern does not indicate of error details The error details could be retrieved from handset

Error Indication


Error Indication

From Wireless Handset (GS02) Retrieve error code (steps)i. Hold down On Timer Cancel or Off Timer Cancel

for 5 seconds until “ ” indication flashes on the handset temperature display section

ii. Press again On Timer Cancel or Off Timer Cancel repeatedly until ID buzzer produces a long beep means there is error occur. Error code will be indicates on the display (refer error code table in the manual)

iii. If it is a short beep or two consecutive beeps, indicates No Error on the unit

iv. To cancel error code display, press On Timer Cancel or Off Timer Cancel for 5 seconds or leave the button not press for 1 minute


From Wireless Handset (GS02) Retrieve last state error (steps)i. Remove battery from the handset and put it in back

ii. Immediately press Mode and On/Off button together until “ “ is being

displayed

iii. Press Mode button until 5:00 is displayed

iv. Press On/Off button once

v. Repeat step (i)

vi. Repeat steps retrieve error code above

Error Indication

ON/OFF button Mode

From Wired controller Netware 3C “ “ and error code will be displayed on the last 2 digits

of the clock display Retrieved last state memory by pressing Sleep and Timer Active together and the error will be displayed

Error Indication

Normal operation

From Outdoori. A5LCY Series I: 7 segment display When there is no error, compressor running frequency

is displayed When there is error, it flashes the error code


Error Indication

Flashing error code

From Outdoori. A5LCY Series I: 7 segment display (con’t) Could also retrieve unit operating condition

i. Press the tact switch, the 7 segment will start to flash from “00”. Press again, it will show “ 01” and subsequent running number

shows the parameter numberii. In split second without pressing the tact switch, parameter measurement of the

particular code above will be displayed
