The time display stops flashing and comes on once the setting is finished.
*Caution
The display automatically goes back to the Clock Display Mode when no panel
operation occurs for more than 60 seconds in the Clock Setting Mode.
If this occurs, changes made will not be reflected to the setting.
If the clock setting is rewound to a time that is earlier than the time when a heating cycle
is triggered, the system will start the heating cycle.
*Note
When no panel operation is performed for more than 60 seconds the display switches to
the Sleep Mode and turns off.
Sleep Mode is cancelled when Up, Down or Enter key is pressed.

This mode is used to set the blackout time that stops the heat pump unit operation within the
selected time.
Blackout times can be used if the customer has a time of use tariff.
Change the mode
Press and hold down Up and Down keys together in the clock display mode to go to the
blackout time setting mode.
Once the mode is changed, 'bo' and '00XX' (00 = start time, XX = end time) are
displayed. (Initial setting = 00 o'clock for both start and end)
Adjust set blackout start time
Press Up or Down key and '00' (start time) in '00XX' starts flashing and 'XX' (end time)
illuminates.
Now the blackout start time can be adjusted.
Setting can be changed only in hour increments, not in minutes.

Press the Enter key to set the desired time setting.
