Priority is given to indoor unit operating in the same mode as the previous cool/heat
master switched OFF operation.
Only no more indoor unit operate in the same mode as the previous cool/heat master,
other RA indoor unit can become cool/heat master to switch to the other operation
mode.
RA indoor unit that is operating, but demanding the other operation mode set by the
cool/heat master, enters the “stand-by mode”: operation LED blinks.
VRV
indoor unit change the operation mode immediately when outdoor unit receives
change of operation mode from the current cool/heat master RA indoor unit.
Field Setting 0:
