The Data Curves screen displays a graphical representation of two pieces of variable data. A ‘red’ trace
for Cooling (Control Valve) Demand and a ‘yellow’ trace for Secondary Supply Temperature T2, both
of which will update in real time (time span of display is 3 minutes).
2.2.5 ALARM Screen
The Alarm screen can be used to view new or active Alarms and to acknowledge these events. Refer
