- Outline forced operation mode includes forced cooling and forced heating operation mode can be selected by the operation mode switch sw2 on the outdoor unit press the forced operation on off switch sw1 on the outdoor unit to start the operation 452
- Wiring error check function 453
- Basic knowledge 454
- Checking the current setting data on the microcomputer memory 454
- Example ex suppose the led indicators are blinking as follows 454
- Refrigerant flows from port a and on the temperatures of the indoor heat exchanger thermistors are detected one by one to check up the matching between the piping and wiring 454
- The above means that port a is connected with port b and port b with room a or self corrected this way 454
- The indoor fan is made to turn on and off at the same time 454
- Those data can be checked by looking at the service monitor led indicators when the wiring error checking is over during forced operation at the stop of the system the led indicators stop blinking when the forced operation is over led1 room a wiring led2 room b wiring 1st blinking led port a piping 2nd blinking led port b piping the 1st blinking led means the room that is connected with port a the 2nd blinking led means the one connected with port b 454
- Trial operation and field settings 454
- Wiring error check function sibe121021_c 454
- With this function on freezing crackling noise may be heard from the indoor unit this is not a problem this is because the heat exchanger temperature is made to drop below 0 c in order to increase the detection accuracy 454

- Address and main sub setting for wireless remote controller 468
- After completing setting seal off the opening of the address setting switch ss2 and the main sub setting switch ss1 with the attached sealing pad 468
- Outline if several wireless remote controller units are used together in the same room including the case where both group control and individual remote controller control are used together be sure to set the addresses for the receiver and wireless remote controller for group control see the attached installation manual for the indoor unit if using together with a wired remote controller you have to change the main sub setting on the signal receiver pcb 468
- Signal receiver pcb set the address setting switch ss2 on the signal receiver pcb according to the table below 468
- Ss2 ss1 468
- When using both a wired and a wireless remote controller for 1 indoor unit the wired controller should be set to main therefore set the main sub setting switch ss1 on the signal receiver pcb to sub 468
- Cancellation of control the control function is canceled when the powerful operation mode is switched off or 20 minutes elapse after powerful operation started 471
- Electronic expansion valves are controlled to provide more capacity to the prioritized room 471

- Outdoor unit 471
- Powerful signal from the priority room unit is received 471
- Priority room setting 471
- Priority room setting is made 471
- Setting method turn off the circuit breaker before changing the setting only one room can be set as the priority room by turning on one of the sw4 on the service monitor pcb of the outdoor unit 471
- The control starts when all the following conditions are met 471
- The prioritized room will be heated cooled much more quickly 471
- Cool heat mode lock 472
- Econo mode proof setting 473
- If night quiet mode is to be used initial settings must be made when the unit is installed explain the function of night quiet mode as described below to the customer and confirm whether or not the customer wants to use night quiet mode night quiet mode function reduces operating noise of the outdoor unit at nighttime this function is useful if the customer is worried about the effects of the operating noise on the neighbors however if night quiet mode is running cooling capacity is reduced 473
- Install the removed jumper switch as described below this jumper switch is needed later to disable this setting 473
- Night quiet mode 473
- Operation the econo mode can be switched over between effective and ineffective by pressing the forced operation on off switch sw1 on the outdoor unit and wiring error check switch sw3 on the outdoor unit at the same time and holding them for 5 seconds while the compressor is stopped the leds are lit in turn for 15 seconds to show the econo mode status the factory setting is effective 473
- Outline when installing in hotels you can make econo mode ineffective on the outdoor unit 473
