Time setting and block out time setting
Current time setting
As part of the water heating cycle the system references the time on the controller.
The system operates at its optimal design if the clock is set before starting to use the
product, however if the clock is not set the unit will still operate. The current time can be
set in the Clock Setting Mode as described below. (Refer to figure 13)
*Note
There is no need to adjust the time setting for the daylight saving period. Even if the
installation is conducted during the daylight saving period, setting the clock to the ordinary
time (not daylight saving time) is preferable.
1. Switching to Clock Setting Mode
Press the "Enter" key in the Clock Display Mode to switch to the Clock Setting Mode.
Time Display starts flashing once the mode is switched.
2. Setting the Clock
The time setting can be adjusted by pressing "Up" and "Down" keys. Fast forward
and rewind are available by pressing and holding down a key.
3. Confirming Time Setting
After the clock is adjusted to the current time, press the Enter key to confirm the
setting. 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 is performed 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
is switched to the Display Sleep Mode and turns off. Display Sleep Mode is
cancelled when Up, Down or Enter key is pressed.
