About priority room function

INFORMATION
▪ The priority room function requires initial settings to be
made during the installation of the unit. Ask the
customer in which rooms he plans to use this function
and make the necessary settings during installation.
▪ The priority room setting is only applicable for an air
conditioner indoor unit and only one room can be set.
The indoor unit for which the priority room setting is applied takes
priority in the following cases:
▪ Operation mode priority: If the priority room function is set on an
indoor unit, all other indoor units enter the standby mode.
▪ Priority during high-power operation: If the indoor unit on which
the priority room function is set operates at high power, the other
indoor units will run with reduced capabilities.
▪ Quiet operation priority: If the indoor unit on which the priority
room function is set to quiet operation, the outdoor unit will also
run quietly.
Ask the customer in which rooms he plans to use this function and
make the necessary settings during installation. Setting it in the
guest rooms is convenient.
To set the priority room function
1 Remove the switch cover on the service PCB.
2 Set the switch (SW4) for the indoor unit for which you want to
activate the priority room function to ON.
