NOTES:

1. Since the outdoor side electric wiring may change be sure to check the outdoor unit electric wiring for servicing.

2. Indoor and outdoor connecting wires are made with polarities, make wiring matching terminal numbers (1, 2, 3).

3. Symbols used in wiring diagram above are, : Connector, : Terminal (block). [Self-diagnosis]

Please refer to technical manuals etc. [Emergency operation procedure]

1.When the indoor unit microcomputer has failed, but all other components work properly, if you set the switch(SWE,SW6)on the indoor control board, the indoor unit will begin Emergency Operation.

2.When you activate emergency operation of the cooling or heating, you have to set the switch(SWE)and switch(SW6)on indoor controller. SWE:ON · Indoor fan is running high speed. · Drain-up machine(optional)is working. SW6-1:ON · Emergency operation of cooling mode. SW6-1,2:ON · Emergency operation of heating mode.

3.Before you activate emergency operation, check the following points:

(1) Emergency operation cannot be activated when:

· The outdoor unit malfunctions. · The indoor fan malfunctions.

(2) Emergency operation becomes continuous only by switching the power source on / off. ON / OFF on the remote control or temperature control etc. does not function. (3) Avoid operating for a long time when the outdoor unit begins defrosting while emergency operation of the heating is activated, because it will start to blow cold air. (4) Emergency cooling should be limited to 10 hours maximum(The indoor unit heat exchanger may freeze). (5) After emergency operation has been deactivated, set the switches etc. to their original positions. (6) Movement of the vanes does not work in emergency operation, therefore you have to slowly set them manually to the appropriate position.

Each function is controlled by the dip switch and the jumper wire on control p.c. board.

8-9. OUTDOOR UNIT SERVICE FUNCTIONS (OUTDOOR CONTROLLER BOARD)

(1) Compulsory defrosting

1When all of the following conditions are satisfied, pressing SW2 starts the compulsory defrosting.

● During HEAT mode

● The compressor is ON.

● The outdoor coil temperature is being displayed by LED. (Outdoor controller board dip switch SW3-1 : OFF, SW3-2 :

ON)

● The outdoor coil thermistor reads 8°C or below.

2The operation state and the termination conditions of the compulsory defrosting are the same as those of the normal

defrosting. As an exception, the defrost interval after the defrosting completion is 50 minutes.

(2) Fixed fan-output

While the compressor is operating (except during defrosting) and the fan output step is indicated by LED, pressing SW2 fixes the fan output. The fixed fan-output can be released when any of the following conditions are satisfied.

1SW2 is pressed again. 2SW3 setting is changed. 3The compressor stops. 4Defrosting operation starts.

(3) Function of switches on the outdoor controller board

SW1: Clears the check code memory (push-button switch) SW2: Switches the output state indication and the check code display (push-button switch) SW3-1,2: Switches the output state indication items (dip switch)

(4) 100% fan output

Fan output is fixed to 100% by shorting the connector CN22. However, the fan stops during compressor OFF or defrosting. Open-circuit of CN22 restarts the normal fan control.

(5) Time shortening

Short circuit of the connector CN21 shortens the time as follows

1Fan control period: 30 seconds → 3 seconds 2Three-minutes time delay function : 3 minutes → 3 seconds 3Max. time of defrosting : 15 minutes → 15 seconds 4Defrost interval : 30 ~ 120 minutes → 3 ~ 12 seconds 5Compressor ON/OFF time for bypass valve ON/OFF : 30 minutes → 3 seconds 6Compressor ON time to start other functions : x minutes → x seconds 7Crankcase heater operation : 1 hour → 6 seconds

(6) Crankcase heater control

1With jumper wire J3

The crankcase heater is ON from when the power is turned ON until the compressor starts, and then turns ON one hour

after the compressor stops.

2Without jumper wire J3 The crankcase heater is ON from when the power is turned ON until the compressor starts, and repeats 1-hour ON and 1hour OFF, after the compressor stops.

• Whenever a power outage or switching of the power supply causes the power supply of an operating air conditioner to go from OFF to ON, this function will automatically restore the operation of the air conditioner to its previous operating mode. w If the power is turned from OFF to ON when the air conditioner is not in operation, the air conditioner will not automatically

be turned on. However, the timer operation will be cancelled if the air conditioner is in timer operation (including when the unit is waiting for its start time). Setting for timer operation must be performed once again.

• If there is a momentary power outage of less than one second while the air conditioner is in operation, there may not be a clear determination of whether or not there was a power failure. When it has been determined that there has been a power failure, recovery will take approximately four minutes after the power is restored. Please wait. (Once "PLEASE WAIT" has appeared on the display, a protection system will operate to prevent the unit from restarting for three minutes.)

When it has been determined that there has been no power failure, operation will continue as is.

• Settings can be made by function selections from the remote controller.

• When there is group control, selection of all refrigerants is required.

10-6. INDIVIDUAL CONTROL OPERATION FROM A SEPARATE ROOM

• By simply centralizing the remote controllers installed in each room in a separate control room, individual control or centralized monitoring of the air conditioners in each room can be attained.

• Air conditioner control can be performed up to a total of 500 meters away by connecting the indoor units and remote controllers with 0.3 to 1.25 mm22-core cable.

• If a remote controller is installed in a room and control room, refer to the section on operating with two remote controllers.

10-7. COMBINED REMOTE/LOCAL CONTROL

• Operation/remote controller prohibit/ stop can be controlled from a remote location by routing the remote stop/start adapter (PAC-SE55RA-E sold separately) through the relay box installed on site. When this remote control is cancelled, the local remote controller can be used for operating and stopping the air conditioner.

1. Basic system wiring

• Use the remote start/stop adapter (PAC-SE55RA-E) and connect the "Start/Stop Circuit From Remote Location" that comes from the relay box and remote/local selection switch and connect it to the CN32 connector on the printed circuit board for the indoor unit

1 Match the rated power supply voltage of the remote/local selection switch and relay (X2) with the power supply for the con-

troller.

2 When performing group control of multiple outdoor unit using a timer, be sure to arrange the timer so that all units do not start

at the same time. If this is not performed, all of the units will start at one time creating an over current that will cause the circuit breaker to operate.

3 An on-delay system is one that includes specifications for operating a limited time when an on signal is received and has a tem-

porary off timer for recovery operations.

4 Use a connecting relay when the wiring length exceeds 10 meters, such as when performing remote wiring. If this is not pro-

vided, abnormal operation will occur.

2. Examples of system applications

In any of the following examples, there is a five to six second delay from the time the operating command is issued until the operation begins. 1 This is when starting and stopping is performed by remote operation or external timer and when starting and stopping by

the remote controller is to be prohibited.

2 This is when starting and stopping is performed by remote operation or external timer and when starting and stopping by

the remote controller is to be separated.

3 This is when starting and stopping is performed by remote operation and then allowing starting or stopping by remote con-

trol at any time.

4 This is when permitting or prohibiting operation by remote controller is performed by external circuit.

Use momentary switch for SW2. (Manual operation/automatic recover switch on time is more than one second.) Press SW2 (on time is more than one second) and operation starts. After this has been done, stopping or restarting can be down by remote controller.

If SW2 is on, operation by remote controller cannot be performed. If SW2 is off, operation by remote controller is permitted.

separately) to the CN2L (Remote kit) on the circuit board of the indoor unit. This function must be selected from the remote controller.

1 Summary of wiring

● Connect the Lossnay linkage cable (Model PACSB81VS) connector to CN2L on the indoor unit on the circuit board of the indoor unit.

● Connect the lead wire of the Lossnay linkage cable to the Lossnay external control input terminal blocks (1) and (2) (At this time, the input terminal blocks (1) and (2) have no polarity.)

2 Precautions when wiring

● The Lossnay linkage cable can be extended up to a maximum of 500 meters. When extending the Lossnay linkage cable, be sure to connect securely and take proper steps to ensure insulation. (Extension cable specifications: Sheathed vinyl cord or cable 0.5 to 0.75mm

● Lossnay linked cable

● Arrange wiring so that there can be no contact between the Lossnay linkage cable and the power supply cord. Contact

may cause malfunctioning. (Separate by 5cm or more.)

)

10-11. OBTAINING HUMIDIFIER SIGNAL

● The humidifier signal that is linked to the AC heating operation (indoor unit ventilator) can be obtained by connecting the adapter for the humidifier signal to connector CN25 on the printed circuit for the indoor unit and wiring it to the humidifier unit via the on-site relay box. There is no output when the thermostat is off, during heating preparation and during defrosting.

W Please consult your nearest Mitsubishi Electric

representative for information about obtaining the adapter for humidifier signal.

10-12. EXTERNAL MOUNTING OF TEMPERATURE SENSOR
