Select the power cable in accordance with relevant local and national regulations. Wire size must comply with local and national code. Power Supply cords of parts of appliances for outdoor use shall not be lighter than polychloroprene sheathed flexible cord. (Code designation IEC:60245 IEC 57 / CENELEC: H05RN-F or IEC:60245 IEC 66 / CENELEC: H07RN-F) You should connect the power cable into the power cable terminal and fasten it with a clamp. The unbalanced power must be maintained within 10% of supply rating among whole indoor units. If the power is unbalanced greatly, it may shorten the life of the condenser. If the unbalanced power is exceeded over 10% of supply rating, the indoor unit is protected, stopped and the error mode indicates. To protect the product from water and possible shock, you should keep the power cable and the connection cord of the indoor and outdoor units in the iron pipe. Connect the power cable to the auxiliary circuit breaker. An all pole disconnection from the power supply must be incorporated in the fixed wiring(3mm). You must keep the cable in a protection tube. Keep distances of 50mm or more between power cable and communication cable. Maximum length of power cables are decided within 10% of power drop. If it exceeds, you must consider another power supplying method. The circuit breaker(ELCB or MCCB+ELB) should be considered more capacity if many indoor units are connected from one breaker. Use round pressure terminal for connections to the power terminal block. For wiring, use the designated power cable and connect it firmly, then secure to prevent outside pressure being exerted on the terminal board. Use an appropriate screwdriver for tightening the terminal screws. A screwdriver with a small head will strip the head and make proper tightening impossible. Over- tightening the terminal screws may break them. See the table below for tightening torque for the terminal screws.

Advanced function: Controlling cooling/heating current or power saving with motion detect.
(1) Minimizing fan operation when thermostat is off – Fan operates for 20 seconds at an interval of 5 minutes in heat mode.
(2) 1: Fan is turned on continually when the hot water heater is turned on, 3: Fan is turned off when the hot water heater is turned on with cooling only indoor unit Cooling only indoor unit: To use this option, install the Mode Select switch (MCM-C200) on the outdoor unit and fix it as cool mode.

(*3) When the following 2 or 3 is used as external heater On/Off signal, the signal for monitoring external contact control will not be output. 2: Fan is turned on continually when the external heater is turned on, 3: Fan is turned off when the external heater is turned on with cooling only indoor unit Cooling only indoor unit: To use this option, install the Mode Select switch (MCM-C200) on the outdoor unit and fix it as cool mode.

If Fan is set to off for cooling only indoor unit by setting the SEG9=3 or SEG15=3, you need to use an external sensor or wired remote controller sensor to detect indoor temperature exactly.
(*4) Default setting value – 4Way Cassette, Mini 4Way Cassette: 5 °C – Other indoor units: 2 °C

(*5) This function can be applied to 4 Way Cassette and Mini 4 Way Cassette only. If the air conditioner operates the heating mode immediately after finishing the cooling mode, the condensated water in the drain pan becomes water vapor by the heat of the indoor unit heat exchanger. Since the water vapor might be condensed on the indoor unit, which may fall into a living space, use this function to get rid of the water vapor out of the indoor unit by operating the fan (for maximum 20 minutes) even when the indoor unit is turned off after cooling mode is turned to heating mode .

(1) Height difference : The difference of the height between the corresponding indoor unit and the indoor unit installed at the lowest place. For example, When the indoor unit is installed 40m higher than the indoor unit installed at the lowest place, select the option “1”.
(2) Distance : The difference between the pipe length of the indoor unit istalled at farthest place from an outdoor unit and the pipe length of the corresponding indoor unit from an outdoor unit. For example, when the farthest pipe length is 100m and the corresponding indoor unit is 40m away from an outdoor unit, select the option “2”. (100 – 40 = 60m)
(*3) Heater operation when the SEG9 of 02 series installation option is set to using hot water heater or when SEG15 is set to using external heater
e.g. 1) Setting 02 series SEG9 =”1″ / Setting 05 series SEG18 = “0”: Hot water heater is turned on at the same time as the heating thermostat is on, and turned off when the heating thermostat is off.
e.g. 2) Setting 02 series SEG15 =”2″ / Setting 05 series SEG18 =”A”:
Room temp. set temp. + f(heating compensation temp.)
– External heater is turned on when the temperature is maintained as 4.5 °C for 10 minutes.
Room temp. > set temp. + f(heating compensation temp.)
– External heater is turned off when the temperature is maintained as 4.5 °C + 1 °C (1 °C is the Hysteresis for On/Off selection.)
