«Important» Do not install the controller in a place where the difference between the remote controller surface temperature and the actual room temperature will be great. If the temperature difference is too high, room temperature may not be adequately controlled. To avoid deformation and malfunction, do not install the remote controller in direct sunlight or where the ambient temperature may exceed 40°C (104°F) or drop below 0°C (32°F).
■ Direct wall installation • Seal the hole through which the cable is threaded with putty. Remote controller cable Seal the gap with putty. To reduce the risk of electric shock, shorting, or malfunctions, keep wire pieces and sheath shavings out of the terminal block. Route the cable behind the remote controller. «Important» Do not use solderless terminals to connect cables to the terminal block.
Route the wire to the top case. Connect the connector on the bottom case to the connector on the top case. Securely connect the connectors. «Important» To prevent malfunctions, do not remove the protective film or the circuit board from the casing. To prevent cable breakage and malfunctions, do not hang the top controller casing hang by the cable. Route the wire to the top case.
Uninstalling the front cover Insert a flat-tip screwdriver or a Plate service tool into either of the two latches at the bottom of the remote controller, and move it in the direction of the arrow as shown in the figure at right. Note that the top case may also be removed if the driver or the tool is inserted deeply.
6.Connecting the transmission wire The remote controller wiring differs according to whether it is connected to a multi air conditioner or Mr. Slim air conditioner. The method also varies according to the system configuration. Always check before starting. (1) Connecting to a multi air conditioner (a) to (d) in the following figure correspond to (a) to (d) in the explanations.

1. Remote Controller (Standerd) Operation 1-1.
2. 2-remote Controller Operation 2-1.
3. Group Control Operation (Collective Operation And Control Of Multiple Refrigerant Systems (2 to 16)) ● Multiple Mr.Slim air conditioners can be operated with the same settings (e.g., operation mode, preset temperature, etc.) by using 1 remote controller. Each outdoor unit can be turned ON / OFF individually by the intake sensor. ● Up to 16 refrigerant systems can be controlled as a group by 1 remote controller. ● A refrigerant address must be set for each outdoor unit.
• Connect the remote controller to one of the indoor units, and connect each refrigerant system with a crossover wire. Always wire from the indoor unit. • Set the refrigerant address for each outdoor unit, and turn the power ON. Set the refrigerant address before turning the power ON. * The power for the remote controller is supplied from the address 00 indoor unit. (LED2 on the indoor control board will light.
4. Power Outage Automatic Recovery Operation ● 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. ● 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.
6. Mode set by external input 6.1 Low -level sound priority mode (Local wiring) By performing the following modification, operation noise of the outdoor unit can be reduced by about 3-4 dB. The low noise mode will be activated when a commercially available timer or the contact input of an ON/OFF switch is added to the CNDM connector (option) on the control board of the outdoor unit. ● The ability varies according to the outdoor temperature and conditions, etc.
