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.
- If address setting using the DIP switches is carried out after
automatic address setting has been carried out, use DIP switch
No. 3 (SW3) 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 setting.
If automatic address setting is carried out once
and then the slave unit address are set, the
address 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.
20.1.3. DIP switch settings for twin/triple 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. / (Set DIP switches 1-1 and 1-8
both to ON. / The unit will become slave unit 2.) / 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 is made while the power is still turned
on, it is easier to mis-combine the setting with
group settings. So, the setting should be made
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 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,
