[Emergency operation procedure] ()Set the dip switch (SW3<I.B>) on the indoor controller board to on and off for cooling and - on for heating. ()Turn on are outdoor unit side circuit breaker, then indoor unit side circuit breaker. (3)During emergency operation indoor fan runs at High speed but auto-vane does not work. ()Thermostat will not function. Cold air blows out for defrosting during heating thus do not operate defrosting for a long time. (5)Emergency cooling should be limited to 0 hours maximum. (The indoor unit heat exchanger may freeze). (6)After every emergency operation, set all dip switches (SW3<I.B>) to. (7)Movement of the vanes does not work in emergency operation, therefore you have to slowly set them manually to the appropriate position. TE: If the drain water lift up mechanism is identified to be defective with the microcomputer doctor during cooling, do not use emergency operation (it causes drain overflow) 6

() Compressor control 3-minute time delay To prevent overload, the compressor will not start within 3 minutes after stop. The compressor runs when room temperature is higher than set temperature. The compressor stops when room temperature is equal to or lower than the set temperature. The compressor maintains the previous state when the discharge temperature minus the set temperature is 0 C or more, or lower than C. 3 The compressor stops in check mode or during protective functions. Coil frost prevention To prevent indoor coil frost, the compressor will stop when the pipe thermistor (RT) reads C or below after the compressor has been continuously operated for at least minutes or more. When the pipe temperature rises to 0 C or above, the compressor will start in a 3-minute(w) time delay. w When the pipe temperature is - C or less, the compressor starts in 6 minutes. TE : By turning the dip switch SW-3 on indoor controller board, the start temperature of coil frost prevention changes from C to -3 C. 33

34 5 Coil frost protection When the pipe temperature becomes -5 C or below,coil frost protection will proceed as follows. <Start condition> After the compressor has been continuously operated for 3 minutes or more,and the pipe temperature has been -5 C or below for 3 minutes,the coil frost protection will start. <Coil frost protection> Compressor stops for 6 minutes, and then restarts. lf the start condition is satisfied again during the first 0 minutes of compressor operation, both the indoor and outdoor units stop, displaying a check code of P6 on the remote controller. <Termination conditions> Coil frost protection is released when the start condition is not satisfied again during the allowance, or when the COOL mode stops or changes to another mode. () Indoor fan control Indoor fan speed LOW/HIGH depends on the remote controller setting. However, if an outdoor unit abnormality is detected, the indoor fan speed will be LOW, regardless of the remote controller setting. ( i ) Fan speed LOW/HIGH depends on the remote controller setting regardless of the thermostat /. (ii) Fan speed will remain on LOW if an abnormality in outdoor unit is detected. (5 minutes) TE : Fan stops immediately if the unit stops or the check mode is started. (3) Auto vane control Auto vane position is set to degrees airflow at the start-up of COOL operation.

One hour later, the airflow direction returns to degrees automatically and Hr will disappear. If the airflow direction is set to degrees during Hr indication, the time counting for AUTO RETURN is cancelled. 3

35 () Detecting abnormalities in the outdoor unit After the compressor has been continuously operated for 3 minutes, if the difference between the pipe temperature and room temperature is out of RANGE C for minute, the indoor fan speed will turn to LOW. Five minutes later, if the difference is still out of RANGE C,the outdoor unit is functioning abnormally. Thus, the compressor stops and check code P8 appears on remote controller.

72 SYSTEM CTROL. VARIETY OF SYSTEM CTROL FUNCTIS Group control with a single remote controller (See page 73.) Unit Remote controller Unit Unit Many units, installed at different locations, can be started and controlled with a single remote controller. The remote controller can be mounted in a different location using a non-polar two-wire cable, which can be extended up to 500m. A maximum of 50 units can be controlled with a single remote controller. All units operate in the same mode. Control using two remote controllers (See page 7.) Unit Unit Unit Two remote controllers can be used to control either one unit or a group of units. Units can then be controlled from a distance or at close range. Units operate according to the latest command from either remote controller. Remote controller 3 Both remote / and individual controls (See page 7.) w Timer adapter (PAC-SA89TA-E) is needed. Individual control by grouping remote controllers (See page 75.) Optional adapter Remote / switch Remote controller Unit Remote controller Unit Unit Relay box Unit All units can be turned on or off simultaneously using a remote - switch. Also, each unit can be controlled individually by each remote controller. Dunning remote - control, a message of CENTRALLY C- TROLLED is displayed on the LCD of the remote controller. This is available for both one unit control and several units control. By grouping the remote controllers in one place, several units installed at different locations can be controlled individually, and operation conditions of all units are visible without a special control board. The control method is the same as that of the single unit with a single remote controller. 5 Multiple remote control display (See page 76.) w Multiple display adapter (PAC-SA88HA-E) is needed. Remote controll display board Unit Unit Remote controller Unit Several units can be controlled with a remote control display board. Operation conditions of all the units are visible with the remote control display board. Individual control by each remote controller is also possible. 6 Auto restart function (See page 76.) Circuit breaker Remote controller A unit can be started or stopped with the circuit breaker on or off. Remote controller is also available. With this function, when the power is restored after power failure, the unit will restart automatically. (However, when the remote controller POWER / button is, the unit will not start.) 7

73 . GROUP CTROL WITH A SINGLE REMOTE CTROLLER A maximum of 50 units can be started in order according to the dip switch settings - How to wire () Connect the remote controller to the double terminal block on the indoor controller board of the master unit (No.0 unit). (See Figure.) () Connect the double terminal block of the master unit to the double terminal block of No. unit. (3) Connect the double terminal block of No. unit to the double terminal block of No. unit. () Continue the process until all the units are connected with two-wire cables. (See Figure.) (5) Remove the connector CN0 from the indoor controller board of each unit except the master unit. (See Figure 3.) (6) Set the unit-address of each unit with SW on the indoor controller board following the instructions below. - How to set unit-address The unit-address also serves as a successive-start timer which starts each unit at intervals of second. If two or more units have the same unit-address in a group control, operation stops due to system error. Be sure to set SW correctly following the instructions below. () Each lever of SW shows the number as follows. SW- : SW- : 8 SW- : SW-5 : SW-3 : SW-6 : 3 () Total number of levers turned to shows the address of the unit. For example, to set No.3 unit, turn SW- and SW-. (3) In this way, set from the master unit to the last unit. Do not forget to set the master (No. 0) unit.

74 3. CTROL USING TWO REMOTE CTROLLERS : OPTIAL REMOTE CTROLLER (PAR-JA0KA) Two remote controllers can be used to control either one unit or a group of units. Units operate according to the latest command from either of the two remote controllers. Before operation, be sure to set one remote controller as the main controller and the other as the sub controller, using dip switch SW7-7 of the remote controller. Figure Individual operation Multiple operation Remote controller Remote controller Remote controller Remote controller 3- How to set SW7-7 (See Figure 5.) () For the main remote controller, turn SW7-7. () For the sub remote controller, turn SW Remote controller LCD indication () The same indications always appear on both the main and sub remote controllers, except during the timer operations. () Timer operations can be set with either of the two remote controllers. However, LCD indication appears only on the remote controller used for timer-settings. (3)If both remote controllers are set for timer operation with different time-settings, the timer operation with the shorter remaining-time is effective. () Self-diagnostic function is available with either of the two remote controllers. If one of the remote controllers is used for the self-diagnostic function, the other remote controller displays the check mode. If the self-diagnostic function is reset by either of the two remote controllers, both remote controllers are reset. Figure 5 Main remote controller Remote controller SW7 Sub remote controller Turn SW7-7.. REMOTE - AND INDIVIDUAL REMOTE CTROLS This method is available to control one unit or any number of units. The following operations are available by connecting a relay, a timer adapter (PAC-SA89TA-E), and a remote / switch to the system. Timer adapter is an optional part. Other parts are available on the market. (A) To start all units in order by remote - switch (B) To stop all units simultaneously by remote - switch (C) To switch between the remote - control and the individual remote control - System Figure 6 shows the case of three units. The same is the case with any number of units.

75 TE : Install the relay box where you can be serviced it easily. TE : For control circuit wiring, use a wire of No. AWG or a control cable according to the power supply of control circuit. TE3 : When the power supply of the control circuit is 0/0V AC, Do not connect the control circuit wire to the remote controller cable directly. Do not place the control circuit wire and the remote controller cable into the same conduit tube. - Basic wiring Caution : Before starting all units simultaneously by the remote - switch, be sure to connect a sequence-start timer into the remote - circuit. Otherwise, a rush of starting current may damage the power supply.

INDIVIDUAL CTROL BY GROUPING THE REMOTE CTROLLERS Grouping the remote controllers allows individual control and centralized monitoring of units installed in different places without a special control board. Remote control cables are extendible up to 500m. When the cable length exceeds m, use the double-insulated two-care cable such as Belden 907. Also, the cable thickness must be No. AWG or above. When gathering the power / switches of air conditioners near the remote controllers, you should also install the power / switch near each unit to prevent electric trouble during servicing.

AUTO RESTART FUNCTI By setting the dip switch SW-8 to, the air conditioner can be started/stopped by power supply /. If the air conditioner is before the power failure, it will not start operation by power restore. This function is mainly to emergency performance when the power supply stops temporarily. Therefore, since the protection function (for example, clank case heater and prevention from restarting in 3 minutes, etc.) of the device is not operated, this function should not be used mostly. 8.
