How to measure the indoor air wet-bulb/dry-bulb temperature difference
1. Attach at least 2 sets of wet-and dry-bulb thermometers to the indoor air intake as shown in the figure, and at least 2 sets of wet-and dry-bulb thermometers to the indoor air outlet. The thermometers must be attached to the position where air speed is high.
2. Attach at least 2 sets of wet-and dry-bulb thermometers to the outdoor air intake. Cover the thermometers to prevent direct rays of the sun.

(4) The initial set temperature is decided by the initial room temperature.
❈1 When the system is restarted with the remote controller, the system operates with the previous set temperature regard-
less of room temperature at restart. The set temperature is calculated by the previous set temperature.
(5) TEMPERATURE buttons
In “I FEEL CONTROL” ( ) mode, set temperature is decided by the microprocessor based on the room temperature. In addition, set temperature can be controlled by TOO WARM or TOO COOL buttons when you feel too cool or too warm. Each time the TOO WARM or TOO COOLbutton is pressed, the indoor unit receives the signal and emits a beep tone.
• Fuzzy control
When the TOO COOL or TOO WARM button is pressed, the microprocessor changes the set temperature, considering the room temperature, the frequency of pressing TOO COOL or TOO WARM button and the user’s preference to heat or cool. So this is called “Fuzzy control”, and works only in “I FEEL CONTROL” mode. In DRY mode of “I FEEL CONTROL”, the set temperature doesn’t change.

2. Coil frost prevention
① Temperature control
When the indoor coil thermistor RT12 reads 3°C or below(MSH-18/24RV)/ RT12 or RT13 reads -1°C or below(MSH-30RV), the coil frost prevention mode starts immediately.
However, the coil frost prevention doesn’t work for 5 minutes since the compressor has started.
The indoor fan operates at the set speed and the compressor stops for 5 minutes. After that, if RT12 still reads below 3°C(MSH-18/24RV)/ RT12 or RT13 still reads below-1°C(MSH-30RV) this mode prolonged until the RT12 reads over 3°C(MSH-18/24RV)/ RT12 or RT13 still reads over-1°C(MSH-30RV).
② Time control
When the three conditions as follows have been satisfied for 1 hour and 45 minutes, compressor stops for 3 minutes. a. Compressor has been continuously operating. b. Indoor fan speed is Low or Med. c. Room temperature is below 26°C. When compressor stops, the accumulated time is cancelled and when compressor restarts, time counting starts from the beginning. Time counting also stops temporarily when the indoor fan speed becomes High or the room temperature exceeds 26°C. However, when two of the above conditions (b.and c.) are satisfied again. Time accumulation is resumed.

3. Outdoor fan speed control <MSH-24/30RV>
Outdoor fan speed is controlled according to the temperature of ambient temperature thermistor RT63. Outdoor fan Low operation : When the outside temperature decreases to 28°C(MSH-24RV)/ 23°C(MSH-30RV) or less.
Until the outside temperature goes to 31°C(MSH-24RV)/ 27°C(MSH-30RV).
Outdoor fan High operation : Until the outside temperature decreases to 28°C(MSH-24RV)/ 23°C(MSH-30RV) or less.
When the outside temperature goes to 31°C(MSH-24RV)/ 27°C(MSH-30RV).
NOTE1. : If the temperature of RT63 reads from 28: to 31:(MSH-24RV)/ from 23:to 27:(MSH-30RV) at the air
conditioner starting outdoor fan speed is High.
NOTE2. : <MSH-30RV>
When indoor fan speed is Low except HEAT operation mode and the outside temperature is 29: or less, the outdoor fan operates at Low.
Outdoor fan Low operation is cancelled according to the following conditions(
1 or 2): 1 When the operation is not changed and the outside temperature goes to 31: or more. 2 When the operation is changed. (Change to HEAT operation mode / Change of the indoor fan speed)
4. Discharge temperature protection <MSH-30RV>
The compressor is controlled by the temperature of discharge temperature thermistor RT62 for excess rise protection of compressor discharge pressure.
• Compressor When the temperature of discharge temperature thermistor RT62 goes to 120: or more, the compressor is turned OFF.
After 3 minutes since the compressor has been turned OFF, if the temperature of discharge temperature thermistor RT62 becomes 100: or less, the compressor is turned ON.
9-1-2. DRY mode of “I FEEL CONTROL”
The system for dry operation uses the same refrigerant circuit as the cooling circuit. The compressor and the indoor fan are controlled by the room temperature. By such controls, indoor flow amounts will be reduced in order to lower humidity without much room temperature decrease.

Set time : 1 minute ➔ 1-second Set time : 3 minute ➔ 3-second (It takes 3 minutes for the compressor to start operation. However, the starting time is
shortened by short circuit of JPG and JPS.)
10-4. P.C. BOARD MODIFICATION FOR INDIVIDUAL OPERATION
A maximum of 4 indoor units with wireless remote controllers can be used in a room. In this case, to operate each indoor unit individually by each remote controller, P.C. boards of remote controller must be modified according to the number of the indoor unit.
How to modify the remote controller P.C. board
Remove batteries before modification. The board has a print as shown below :
The P.C. board has the print “J1” and “J2”. Solder “J1” and “J2” according to the number of indoor unit as shown in Table 1. After modification, push the RESET button.
52
NOTE : For remodelling, take out the bat-
teries and push the OPERATE/STOP(ON/OFF)button twice or 3 times at first. After finish remodelling, put back the batteries then push the RESET button.

NOTE : At power supply failure or installation, indoor unit deletes the memory about remote controller. When the power supply
is turned on and indoor unit receives the first signals from the remote controller, the remote controller number is desig­nated as the indoor unit number. Therefore at and after the second time indoor unit accepts the remote controller of the initial setting number. At setting - error, turn the power supply off to cancel the individual operation and then turn the power supply on to restart the setting.
10-5. AUTO RESTART FUNCTION
When the indoor unit is controlled with the remote controller, the operation mode, set temperature, and the fan speed are memorized by the indoor electronic control P.C.board. The “AUTO RESTART FUNCTION” sets to work the moment power has restored after power failure.Then, the unit will restart automatically. However if the unit is operated in “I FEELCON­TROL” mode before power failure, the operation is not memorized. In “I FEEL CONTROL” mode, the operation is decided by the initial room temperature.
How to set “AUTO RESTART FUNCTION”
1Turn off the main power for the unit. 2Pull out the electronic control P.C.
board and the display P.C.board. (Refer to page 73 or 75.)
3Cut the RESISTOR JR06 (MSH-
18/24RV) / JR07 (MSH-30RV) on the indoor electronic control P.C.board. (Refer to page 69 or 70.)
Operation
1If the main power (220-240V AC) has been cut, the operation settings remain. 2After the power is restored, the unit restarts automatically according to the memory.(However, it takes at least 3 minutes
for the compressor to start running.)
NOTE
•The operation settings are memorized when 10 seconds have passed after the remote controller was operated with the
remote controller.
•If main power is turned off or a power failure occurs while AUTO START/STOP timer is active ,the timer setting is
cancelled.
•If the unit has been off with the remote controller before power failure, the auto restart function does not work as the
power button of the remote controller is off.
•To prevent breaker off due to the rush of starting current, systematize other home appliances not to turn on at the same
time.
•When some air conditioners are connected to the same supply system, if they are operated before power failure, the
starting current of all the compressors may flow simultaneously at restart. Therefore, the special counter-measures are required to prevent the main voltage-drop or the rush of the starting current by adding to the system that allows the units to start one by one.

11-1. Cautions on troubleshooting
1. Before troubleshooting, check the following:
(1) Check the power supply voltage. (2) Check the indoor/outdoor connecting wire for mis-wiring.
2. Take care the following during servicing.
(1) Before servicing the air conditioner, be sure to first turn off the remote controller to stop the main unit, and then after
confirming the horizontal vane is closed, turn off the breaker and / or disconnect the power plug.
(2) Be sure to turn OFF the power supply before removing the front panel, the cabinet, the top panel, and the electronic
control P.C. board.
(3) When removing the electronic control P.C. board, hold the edge of the board with care NOT to apply stress on the
components.
(4) When connecting or disconnecting the connectors, hold the housing of the connector. DO NOT pull the lead wires.
3. Troubleshooting procedure
(1) First, check if the OPERATION INDICATOR lamp on the indoor unit is flashing on and off to indicate an abnormality.
To make sure, check how many times the abnormality indication is flashing on and off before starting service work. (2) Before servicing check that the connector and terminal are connected properly. (3) If the electronic control P.C. board is supposed to be defective, check the copper foil pattern for disconnection and the
components for bursting and discolouration. (4) When troubleshooting, refer to the flow chart on page 55 or 56 and the check table on page 57 or 58.
4. How to replace batteries
Weak batteries may cause the remote controller malfunction. In this case, replace the batteries to operate the remote controller normally. 1 Remove the front lid and insert batteries.
Then reattach the front lid.
2 Press the RESET button with tip end of ball point
pen or the like, and then use the remote controller.
NOTE1. : 1. If the RESET button is not pressed, the remote controller may not operate correctly.
2. These illustrations of remote controller are MSH-18/24RV.
NOTE2. : INFORMATION FOR MULTI SYSTEM AIR CONDITIONER
(OUTDOOR UNIT : MXZ-32NV- MXZ-32NV- MXZ-32RV- MXZ-32SV- )
Multi system air conditioner (Outdoor unit MXZ-32NV- MXZ-32NV- MXZ-32RV- MXZ-32SV- ) can connect two or more indoor units with one outdoor unit.
According to the capacity, two or more units can operate simultaneously.
•When you try to operate two or more indoor units with one outdoor unit simultaneously, one for the cooling and the other for heating, the operation mode of the indoor unit that operates earlier is selected. The other indoor units that will start the operation later cannot operate, indicating as shown in the figure below. In this case, please set all the indoor units to the same operation mode.
E1E1E2E1
Operation Indicator
•When indoor units starts the operation while the defrosting of outdoor unit is being done, it takes a few minutes (max. 10 minutes) to blow out the warm air.
•In the heating operation, though indoor unit that does not operate may get warm or the sound of refrigerant flowing may be heard, they are not malfunction. The reason is that the refrigerant continuously flows into it.

● Normal life of AIR CLEANING FILTER is 4 months. However, when it becomes dirty, replace it as soon as possible.
● Clogged AIR CLEANING FILTER may reduce the air conditioner capacity or cause frost on the air outlet.
● DO NOT reuse AIR CLEANING FILTER even if it is washed.
● DO NOT remove or attach AIR CLEANING FILTER during unit operation.
14-2. DEODORIZING FILTER
● DEODORIZING FILTER removes ammonia and hydrogen sulphide emitted from tobacco, and odor of pets.
● Clean DEODORIZING FILTER every two weeks. If the filter is particularly dirty, clean the filter more often.
● For cleaning, soak the filter in warm water for a while, and then wash and rinse it. Dry the filter in the shade thoroughly.
● When the filter color is still dark even after cleaning, replace the filter with a new one.
Replace the filter at least once a year.
