Current time setting
This product contains a built-in clock. As a part of the water heating cycle logic refers to the
current time, it is necessary to set the clock before starting to use the product. The current time
can be set in the Clock Setting Mode as described below.
*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, the clock setting to the
ordinary time (not daylight saving time) is preferable.
1. Switching to Clock Setting Mode
Press the “Enter” key in the 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. Executing Setting the Clock
After the clock is adjusted to the current time, press the Enter key to execute 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 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.
