-
Click on the number of minutes after the hour. The clock display closes, and the user is returned to the Automation Settings
screen.
-
Repeat the above steps for Degas off, Chiller on, and Chiller off.
Note
: The scheduler forces the chiller start time to be at least 30 minutes after the degas start time. Cold bath water does not
degas efficiently. The 30 minute delay permits the water to be sufficiently degassed before it is too cold.
Once degassed, the system will maintain a sufficiently degassed condition regardless of water temperature.
-
Enter the desired chiller set point, in whole degrees, in the Default Temp ºC field.
-
Click on either All, Weekdays, of the single day, in this example Sunday, button at the bottom of the Automation Settings
screen. The Automation Settings screen closes and the Water Works pane is displayed.
In this example, the Weekdays button was clicked.
-
Click Auto Is Off. The button changes to a red Auto Mode button, and chilling and degas will start and stop as
scheduled on weekdays. In Auto Mode, the chiller and degas buttons at the top of the Water Works pane are disabled.

Manual Chiller and Degas Control
: To manually control degassing and chiller operation, click the red Auto Mode button. The
button will change to Auto Is Off, indicating that manual control is enabled.
In Manual Mode, the chiller and degas pump may be toggled on and off by clicking the buttons at the top of the window.
Clicking the “Click for Standby Mode” button places your system and ultraCUBE in standby. The transducer and sample tray move to
the service position, the degas pump turns off, and the chiller heating/cooling unit turns off. The chiller pump will continue to
operate, circulating the bath water through the WCS unit.
Note
: If your system is left in Standby mode, i.e., the transducer is up and out of the water bath, automatically scheduled events will not
occur.
NOTE:
All accounts must be logged out of SonoLab for the automatic temperature control operation. At
the time scheduled for cooling to turn on or off, any logged in user’s method will override the automatic
settings. The automatic settings will not then immediately take effect when this user logs out. The
automatic settings will only take effect at the next scheduled change.
