Time Setting And Block Out Time Setting - Sanden GAUS-315EQTA Installation Manual

Time setting and block out time setting
Current time setting
This product contains a built-in clock IC. 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 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. 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 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.
