Address code about capacity on the mainboard of indoor unit two 4 bit dip switches are used to distribute the address and capacity of indoor units the 4 bit dip switch marked with capacity below used for setting the capacity of indoor units is factory set before shipment of indoor unit while it is covered by sealant so that it cannot be changed by the user below is factory default setting 214

Dial up value the dial up value of address code is set in binary system the dial up value is 0 when the lever is dialed to on end the dial up is 1 when the lever is dialed to numerical end on opposite side for number 4 1 on the address code the dial up 4 refers to high bit and the dial up 1 refers to low bit 214

Example 1 if the dial value is 0111 this represents that the address is 8 the pins 1 2 3 of the dial switch are dialed to the numerical end and the pin 4 is dialed to on example 2 if the dial value is 1010 this represents that the address is 11 the pins 2 4 of the dial switch are dialed to the numerical end and the pin 1 3 are dialed to on see below 214

The default capacity dial up is the maximum capacity of indoor unit as shown above the capacity is see above for the lever position dial up value the dial up value of capacity code is set in binary system the dial up value is 0 when the lever is dialed to on end the dial up is 1 when the lever is dialed to numerical end on opposite side for number 4 1 on the capacity code the dial up 4 refers to high bit and the dial up 1 refers to low bit 214

Functional description of function dial up dial up switch 1 s r setting of memory mode including the standby mode and restoration mode the standby mode refers to that the previous parameters will be kept but the unit will not run automatically after the power supply is resumed this setting is factory defaulted dial up switch pulled to on position for example if the parameters of an indoor unit set before power shutdown are high fan and 24 the unit will be under standby state after the power supply is resumed and after the unit is manually started the parameters will remain as high fan and 24 the restoration mode refers to that not only the previous parameters will be kept but also that the unit can start automatically after the power supply is resumed but if the unit is under stop state before power shutdown it will be also under stop state after the power supply is resumed dial up switch 2 l i setting of control mode including wired control and remote control the wired control mode re 215
