•Operation modes that are not available to the connected indoor unit models will not appear on the display.
What the blinking mode icon means
The mode icon will blink when other indoor units in the same refrigerant system (connected to the same outdoor unit) are already operated in a different mode. In this case, the rest of the unit in the same group can only be operated in the same mode.

Setback mode |
The setback function automatically switches the operation mode between cooling and |
|
heating to maintain the room temperature within the set temperature range. |

Notes on setback operation
•The setback mode can be set from this remote controller only in the systems that have the following type of units:
·Unit that features simultaneous cooling and heating functions: PURY/PQRY series
·Unit that features simultaneous cooling and heating functions with the use of external heaters (Field supply): PUHY series with external heater
Depending on the production month, the simultaneous cooling and heating function is limited on some PUHY units. For the availability of this function, contact a local sales representative.
Type of units other than the types above cannot be operated in the setback mode. In this case, set “No” in the Setback mode setting. Refer to the Initial Setting Manual for details about Setback mode setting.
For PUHY series of units which do not have simultaneous cooling and heating function with the use of external heaters, make sure to use TC-24A for the setback mode.
When using both TC-24A and PAR-30MAAU in a system, make a setting for the setback function only from one of them. Do not make a setting from both of them.
•When the setback operation is performed on the cooling-only units, the upper/lower limit temperature can be set, but only the upper limit temperature is controlled in the operation.
•If the Operation mode changeover limit is set from the system controller, the Setback mode will be canceled, and the Fan mode will be set.
•If the Maintenance or Service function has started, the Setback operation will not switch the operation mode, and the operation mode will remain the same as the one before the Maintenance or Service function has started.
