Automatic address setting for twin system
Procedure:
Turn on the power supply for the indoor and outdoor units.
Operation:
Automatic address setting will start 10 to 30 seconds after the power supply is turned on, and will be completed after about 1
minute.
If the power supplies for the indoor unit and outdoor unit cannot be turned on at the same time, turn on the power supply for the
outdoor unit, the indoor unit which is connected to the remote control, and then the other indoor units in that order.
If the order of turning on the power supply is incorrect, the master unit setting may overlap. In such a case, turn on the power supplies
for all units in the correct order as given above, or carry out a twin/triple automatic address reset (press dip switch 3 on the outdoor
unit continuously for 4 seconds or longer).
• • • • The indoor unit which is connected to the remote control unit (receptor) will have priority for becoming the master unit.
• • • • The master unit thermostat will be used as the indoor temperature thermostat. If the master unit thermostat is turned on, the
slave unit thermostats cannot be adjusted even if they happen to be on.
• • • • DIP switch settings take priority in the setting of twin and triple addresses.
• • • • If address setting using the DIP switches is carried out after automatic address setting has been carried out, use DIP switch
No.3 on the outdoor unit to carry out automatic address resetting.
• • • • If you would like to designate a particular indoor unit as the master unit because no master unit has been set, use the DIP
switches on the slave units to make the setting.
If automatic address setting is carried out once and then the slave unit addresses are set, the addresses will then be stored inside the
EEPROM. Thus it is not necessary to repeat automatic address setting if the power is turned off and back on again.
DIP switch settings for twin slave unit addresses
Procedure:
Turn off the power supply, and then set DIP switch 1-8 to ON.
The unit will become slave unit 1.
Turn on the power supply.
Operation:
The unit will operate as slave unit 1. Automatic address setting is not carried out at this time.
If the setting can be made while the power is still turned on, it is easier to mis-combine the setting with group settings. So, the
setting be made better while the power is turned off.
• • • • Only slave unit addresses can be set in this way. Master unit setting is not possible.
• • • • If you make the DIP switch settings after the power has been turned back on, carry out twin/triple automatic address resetting.
• • • • Be sure to set DIP switch 1-8 to ON when setting twin/triple addresses. If DIP switch 1-1 is set to ON without setting 1-8 to ON
also, group addresses will be set instead, and the remote control open circuit error code (F26) will be displayed.
Automatic address resetting for twin systems
Function
• • • • This clears the current twin addresses which have been set automatically, and causes automatic twin address setting to be
carried out once more.
