(1) Compressor control 1 3-minute time delay To prevent overload, the compressor will not start within 3 minutes after stop. 2 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. 3 The compressor stops in check mode or during protective functions. 4 Coil frost prevention To prevent indoor coil frost, the compressor will stop when the indoor coil thermistor (RT2) reads 1°C or below after the compressor has been continuously operated for at least 16 minutes or more. When the indoor coil temperature rises to 10°C or above, the compressor will start after a 3-minute time delay. NOTE : By turning OFF the dip switch SW1-5, PKH-2.5/3/4 for J1-5 on indoor controller board, the start temperature of coil frost prevention changes 1°C to -3°C. 33 OC132--2.qxp 1.11.8 10:17 AM Page 34 5 Coil frost protection When indoor coil temperature becomes -15°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 indoor coil temperature has been -15°C or below for 3 minutes,the coil frost protection will start. <Coil frost protection> Compressor stops for 6 minutes, and then restarts. If the start condition is satisfied again during the first 10 minutes of compressor operation, both the indoor and outdoor units stop, displaying a check code of “P8” 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. (2) 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. When the outdoor unit abnormality detection is released and the fan speed returns to the set speed, the quiet cycle control will work. (a) Normal control ( i ) Fan speed LOW/HIGH depends on the remote controller setting regardless of the thermostat ON/OFF. (ii) Fan speed will remain on LOW if an abnormality in outdoor unit is detected. (5 minutes) When the abnormality detection is released, the fan speed returns to the set speed. 5 minutes SET 5 minutes 1 Start-up of outdoor unit abnormality detection. 2 Release of outdoor unit abnormality detection. 3 Unit stop due to outdoor unit abnormality with P8 indication.

When all of the following conditions are satisfied, defrosting will start. However, when the bypass valve turns OFF, defrosting starts 10 minutes later. (a) More than seven minutes have passed since the compressor start-up. (b) The outdoor coil thermistor reads -5°C or below. (c) The outdoor fan motor output step is 100% (d) Total time of compressor operation exceeds 30 minutes, and the outdoor coil temperature has fallen by 8 degrees or more in comparison with that of 10 minutes after the compressor start-up. NOTE: The outdoor coil temperature of 10 minutes after the compressor start-up is memorized until the defrosting operation has ended. B. When all of the following conditions are satisfied, defrosting will start. (a) ~ (c) The same as above (a) ~ (c) in item A (d) Total time of compressor operation exceeds “defrost interval”. Further information on the defrost interval is described in (3). C. After the total time of compressor operation exceeds the defrost interval, the thermostat repeats ON/OFF 3 times. Two minutes after the fourth “ON” of the thermostat, if the outdoor coil thermistor reads -5°C or below and the fan output is 100%, defrosting will start. NOTE: The count of the thermostat ON/OFF is cleared by the compressor-OFF command or defrosting start-up. (2) During defrosting ● Even if the thermostat turns OFF, defrosting continues. ● The 4-way valve, bypass valve, outdoor fan, and indoor fan are OFF. 51 OC132--2.qxp 1.11.8 10:17 AM Page 52 (3) Defrost interval The defrost interval time is determined as follows. ● Initial defrost interval is 50 minutes. ● The defrost interval after defrosting depends on the preceding defrosting time as shown below. Defrosting operation time 3 minutes or below Next defrost interval 120 minutes 3 to 7 minutes 80 minutes 7 to 10 minutes 60 minutes 10 to 15 minutes 40 minutes 15 minutes (Maximum) 30 minutes NOTE1:If the unit stops during defrosting , the next defrost interval will be 50 minutes. NOTE2:If a protection function works for the first time during defrosting, the compressor will stop. After a 3-minute time delay, defrosting will restart. In this case, a 3-minute time delay is included with the defrosting time. If the protection function works for the second time, the unit stops operation and displays the check code. The next defrost interval will be 30 minutes. NOTE3:When the defrosting has ended, the total time of the compressor operation is cleared. (4) Termination conditions Defrosting finishes when any of the following conditions are satisfied. 1Defrosting has continued for 15 minutes. 2Outdoor coil thermistor reads 22°C or above for the first 75 seconds after defrosting start-up. 3Outdoor coil thermistor reads 8°C or above after the 75-second defrosting. 4Power ON/OFF button is turned OFF during defrosting. 3-6 Actuators (1) Bypass valve control <Cooling mode> 1When the unit stops due to the coil frost prevention, the bypass valve turns ON. When one hour has passed since the compressor stopped, the bypass valve returns to OFF. 2When the compressor operates with the bypass valve at ON for more than 30 minutes, the bypass valve turns OFF. 3When the compressor stops with the bypass valve at OFF, the bypass valve turns ON and remains ON for three minutes. <Heating mode> 1When the unit starts for the first time after the circuit breaker has been turned ON, or when it starts after the compressor OFF of 30 minutes or more, if the outdoor coil thermistor reads 12°C or more, the bypass valve turns ON. 2When the high pressure switch (63H1) works, the bypass valve turns ON. 3When the bypass has been ON for 30 minutes: ● If the high pressure switch has already returned, the bypass valve turns to OFF. ● If not, the fan output step keeps 70 for three minutes. Meanwhile, if the high pressure switch returns, the bypass valve turns OFF. Otherwise the normal fan control starts. 4When the operation mode changes or stops, the bypass valve turns ON and remains ON for three minutes. <Defrosting operation> 1The bypass valve is OFF. (2) 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 1-hour OFF. 52 OC132--2.qxp 1.11.8 10:17 AM Page 53 3-7 Service functions (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.

(3) Connect the double terminal block of No.1 unit to the double terminal block of No.2 unit. (4) Continue the process until all the units are connected with two-wire cables. (See Figure 2.) (5) Remove the connector CN40 from the indoor controller board of each unit except the master unit. (See Figure 3.) (6) Set the unit-address of each unit with SW2 on the indoor controller board following the instructions below. 2-2 How to set unit-address The unit-address also serves as a successive-start timer which starts each unit at intervals of 1 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 SW2 correctly following the instructions below. (1) Each lever of SW2 shows the number as follows. SW2-1 : 1 SW2-4 : 8 SW2-2 : 2 SW2-5 : 16 SW2-3 : 4 SW2-6 : 32 (2) Total number of levers turned to ON shows the address of the unit. For example, to set No.3 unit, turn ON SW2-1 and SW2-2. (3) In this way, set from the. master unit to the last unit. Do not forget to set the master (No. 0) unit.

REMOTE ON-OFF AND INDIVIDUAL REMOTE CONTROLS 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 ON/OFF 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 ON-OFF switch (B) To stop all units simultaneously by remote ON-OFF switch (C) To switch between the remote ON-OFF control and the individual remote control 3-1 System Figure 6 shows the case of three units.The same is the case with any number of units.

INDIVIDUAL CONTROL BY GROUPING THE REMOTE CONTROLLERS ● 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 12m, use the double-insulated two-care cable such as Belden 9407. Also, the cable thickness must be No. 22 AWG or above. ● When gathering the power ON/OFF switches of air conditioners near the remote controllers, you should also install the power ON/OFF switch near each unit to prevent electric trouble during servicing. 66 Remote controller cable (2-core) Remote controller OC132--3.qxp 1.11.8 10:44 AM Page 67 5.
