12. Operation Mode / Setting Temperature Priority Setting
It is feasible only to set the operation mode and unit temperature setpoint, from one specic controller (the main
controller) in the same refrigerant system without having to use the central station. The sub controller acts in
accordance with the settings of the main controller which is effective management of temperature depending on the
interval of the priority operation mode and power saving settings.
1. Press and hold “Menu” and “Back/Help” simultaneously for at least three seconds while in the normal mode (when unit is
not operated). The Test Run menu is displayed.
2. Select “Priority Setting” from the Test Run menu and press “OK”.
5. Press “Back/Help” on the Test Run menu to return to the normal mode.
3. Press “
” to change the settings in the following order “Not available” ↔ “Operation Mode” ↔ “Operation Mode” +
Setting Temperature”.
4. Select “YES” and press “OK” to conrm and display the Test Run menu. If “NO” is pressed, the screen returns to “3”.

1. 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.
2. 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 temporary overridden.
3. When using two controllers, it is not possible to set priority.
4. If one of the devices in the same refrigerant cycle is connected, the main function cannot be used.

5. It is not possible to operate at the same time cooling and heating mode in the same refrigerant system. If multiple
RC exist within the same refrigerant system, only one RC can give the right to set the operation mode.
