Schedule function
The schedule function key is used to configure the occupancy
schedule.
This function provides a means to automatically switch the chiller
from an occupied mode to an unoccupied mode.
The schedules consist of eight user-configurable occupied time
periods. The control supports time schedules for local control,
remote control and ice building. These time periods can be flagged
to be in effect or not in effect on each day of the week and for
holidays (30 days).
Ice build control automatically sets the chilled water/brine control
point of the machine to a temperature where an ice building
operation for thermal storage can be accomplished.
Service function
This function allows the technician to view and input configuration
data. Factory configuration data (subfunction 1) cannot be
modified.
Options configuration 1 and 2 (subfunctions 2 & 3) as well as all
the other subfunctions, reset/demand limit (subfunction 4), factory
configuration codes (subfunction 5), transducer calibration
(subfunction 7), manual control (subfunction 8) will need a
password to be entered.
