Auto Addressing
Manual Addressing
- If the auto addressing does not work according to the indoor unit capacity, model or installation
condition,apply the manual addressing.
When SW01 set "0"on Auto address mode,it means you install the maximum number of indoor unit.
1) Installation ID Unit Number=MAX Installation ID Unit Number of OD Unit.
Don't need set SW01.
2) Installation ID Unit Number<MAX Installation ID Unit Number of OD Unit.
Pls set SW01 as the number of which you install the indoor unit.
On Manual address mode,you must set SW01 as the number of which you install the indoor unit.
- This mode is for finding the combination between indoor unit and each valve on the outdoor unit. Because refrigerant
flow is controlled with EEV in the outdoor, controller should know which EEV will control which indoor unit.
- Once "PIPE CHECK MODE" is done normally, each indoor unit will remember the given address number by the outdoor
unit and no need to do this checking. But in case of listed below, PIPE CHECK MODE should be done again.
- On this mode the controller will ignore the manual address number set on the rotary switch on the indoor PCB.
- To confirm the indoor address number assigned by this mode, use "TESTMODE" and the address number will be
displayed on the LED display on the indoor unit.
