4.2.7 Date/Time
This page will allow to adjust the time and date in the UC. This time and date will be used in the alarm log and to enable
and disable the Quiet Mode. Additionally it’s also possible to set the starting and ending date for the DayLight Saving time
(DLS) if used. Quiet Mode is a feature that is used to reduce the chiller noise. This is done by applying the maximum
setpoint reset to the cooling setpoint and increasing the condenser temperature target by an adjustable offset.
