SELF-DIAGNOSIS AND TROUBLESHOOTING

Abnormality display

None

F1 F2

Meaning of abnormality display and abnormality troubleshooting

Indoor/outdoor connection erroneous wiring, too many indoor units (5 or more)

1.Outdoor controller board automatically recognizes the number of connected indoor units. However, when the number of connected indoor units cannot be set due to erroneous indoor/outdoor connection, erroneous wiring, etc. even after 4 minutes have elapsed since the power was turned on, an abnormality is recognized.

2.When the outdoor controller board identified “5 or more” connected in- door units, an abnormality is recognized.

Indoor/outdoor connection erroneous wiring

The outdoor controller board automatically sets the unit No. of the indoor units. However, when the unit No. of the indoor units cannot be set due to indoor/outdoor connection erroneous wiring even after 4 minutes has elapsed since the power was turned on, an abnormality is recognized.

Start-up time over

When start-up processing does not end even through 4 minutes has elapsed since the power was turned on, an abnormality is recognized.

faulty, or disconnected.

c. Missing phase (R or S phase)

(2) No electricity at controller board power

supply connector.

a. Power supply connector contact

faulty.

b. Terminal R/1 or S/2 on controller

board disconnected.

(3)Outdoor unit controller board faulty.

a. Blown fuse on controller board. b. Part faulty.

Judgment method and remedy

(1)

a. Check power supply circuit breaker. b. Check power supply terminal block

connections.

c. Check power supply terminal block

connections.

(2)

a. Check power supply connector board

connections.

(3)

a. Replace fuse. b. Replace controller board.

(However, when cannot be repaired even through the check above was carried out.)

(1)Check if indoor unit or outdoor unit in-

door/outdoor connection wire disconnected or loose. Also check polarity.

(2) Check indoor/outdoor wire diameter

and wiring length. Outdoor-indoor: Max. 50m Indoor-indoor (span): Max. 30m Also check that VVF and other flat cables are connected in S1, S2, S3 order. (S2 in the middle)

(3)Check number of indoor units con-

nected to outdoor unit.

(4)Check by turning power off and on.

If abnormality is displayed again, replace outdoor controller board or indoor controller board.

* LED3 of the indoor controller board

flashes when communication is being performed.

(1) Check power supply terminal block

connections.

During thermostat OFF mode, low speed air operation will take place. During thermostat ON mode, low speed air will switch automatically to set notch (fan speed) on the basis of time or piping temperature. During defrosting, the fan will stop. After the switch is turned ON, low speed air will take place, for 7 minutes (or after pipe temperature reaches 35˚C, 2 minutes) before automatically switch to set notch (fan speed). (Hot adjustment) There is a risk of the power to the outdoor unit being connected in reverse phase. Be sure to check that the phase is correct.

When the switch is turned ON, the fan does not begin to operate. (PEH-8, 10)

The outdoor unit fan turns in reverse or stops, and an unusual sound is heard.

The fan setting changes during heating. (PEH-8, 10)

The fan stops during heating.

Note: If the fan in the indoor unit does not operate, check the over-current relay on the fan motor to determine whether it has been tripped. If the over-current relay has been tripped, reset it after eliminating the cause of the problem (e.g. motor lock). To reset the over -current rela y, open the control box and press the green claw on bottom-right of the relay until a c lick is hear d. Release the claw and check that it returns to its original position. Note that if it is pressed too hard it will not return to its original position.

13-5. GROUP CONTROL

(1) Notes on performing group control

• Up to 16 indoor units can be sequentially started up with each remote controller.

• The ON/OFF control of the room temperature is performed individually for each refrigerant system with the inlet

thermistor that is built-in on the unit.

• Up to two remote controllers can be connected to each group. (Up to two wired remote controllers can be connected. There are no restrictions on the number of wireless controllers that can be connected.)

When connecting two remote controllers, the two controllers cannot be daisy-chained. Make the connections through indoor units.

2 Make the refrigerant address setting for each indoor unit, and turn on the power.

Set the refrigerant address before turning on the power. *The remote controller power supply unit is automatically set to the indoor unit with the refrigerant address of 01.

(LED 2 comes on.)

Refrigerant addresses are also used by the sequential start up timer (4 second interval) to prevent rush current. If any of the indoor unit addresses overlap, correct indoor unit cannot be identified during self-diagnosis or function

selection. Assign a different refrigerant address to all indoor units, following the setting procedures below.

At factory shipment, switches 3 through 6 of SW1 are all set to OFF, and the refrigerant address is set to “0.” In this case, the delay time will be between 0 and 9.

* Varies depending on the number of connected indoor units and remote controller operation timing.

According to the combination of switches 3 through 6 above, units can be sequentially started up at 1-second intervals between address 1 and address 15 (Delayed time between 10 and 24 seconds).

(Example) Sequential start up timer set to 12 seconds

Address setting of outdoor unit

Address setting of M-NET (MELANS) [Option]

· Address setting of each outdoor unit is required when group control is used.

· Dip SW1 (3-6) on the circuit board < All are set to OFF at factory shipment. > is used to set the address of outdoor unit.

(Address setting is not required for 1: 1 system and Free Compo Multi.)

· Address setting with SW1 is shown below.

Set M-NET (MELANS) address among 1~50. Assign the smallest address in a group to the M-NET (MELANS) connected with the outdoor unit whose address is 0. (Refer to the wiring connection sample.)

Use the rotary switches SW11 and SW12 inside the control box on the M-NET circuit board to set the address. (SW11: 1's digit, SW12: 10's digit < They are set to 0 at factory shipment. >)

Note that 10's digit is on the right, and 1's digit is on the left on the actual switch.
