Chapter 4 – Using the Control Panel
4.4.8 Filter Life Reset
The Filter Life Reset function allows the Filter Life Monitor to be reset after a new
filter has been inserted. As a result, the appropriate filter life LED on the control
panel will be reset to green and the hour count in the Filter Life Reset display will
be reset to the full life span of the new filter.
Note: Resetting the Filter Life Monitor will also cancel the “Replace Filter” warning
from the main display window.
1. To reach the Filter Life Reset function from the main display window, press the
Menu key seven times.
2. Press and hold the Enter key until the flashing cursor appears. The flashing
filter refers to the filter and its position within the system.
3. Press the ▲ key to select filter that has been replaced.
4. Press the Enter key to confirm that the selected filter has been replaced.
5. To safeguard against inadvertently resetting the life of the wrong filter, the
selection needs to be reconfirmed. To reconfirm the filter change and exit the
Filter Life Reset display window, press the Enter key.
Note: If the wrong filter has been selected, or if you wish to exit the enter
mode, press the Menu key. This leaves the Filter Life Reset unaffected.
6. Upon successful reset of the filter life, the new remaining filter life (taking the
currently selected fan speed into account) will be displayed.
4.4.7 Time & Day Setting

disconnected from the power supply for more than an hour.
1. To access the Time & Day function from the main display window, press the
Menu key six times.
2. Press and hold the Enter key until the cursor starts to flash.

setting.

setting.
