9. Priority Setting
You can only set the operation mode and unit temperature setpoint from one specific controller (the main
controller) in the same refrigerant system without having to use the central controller. The operation of sub
controller is decided by the priority setting and power saving details setting of the main controller.
Example

:

NOTES:
•
This controller comes normally pre-set with factory-supplied default settings. It is possible to set, depending
on what is pre-set in the priority settings of the Test Run menu.
•
Only the temperature setting cannot be set as priority. Also, even if operation mode is set as priority, in the
case of COOL/HEAT Automatic Mode, the priority is temporarily overridden.
•
It is not possible to set the "Cool/Heat Auto Changeover" and "Priority Setting" at the same time. In addition,
the priority will be removed once the "Cool/Heat Auto Changeover" takes effect.
•
When using two controllers, it is not possible to set priority.
•
If one of the devices in the same refrigerant cycle is connected, the main function cannot be used.
