•
The time line indicates the upper level operating
mode, as it would be viewed in the Tracer®
AdaptiView™.
•
The shading color of the cylinder indicates the
software state.
•
Text in parentheses indicates sub-mode text as
viewed in the Tracer® AdaptiView™.
•
Text above the time line cylinder is used to illustrate
inputs to the UC800. This may include user input to
the Tracer® AdaptiView™ touch screen, control
inputs from sensors, or control inputs from a
P o w e r U p
generic BAS.
•
Boxes indicate control actions such as turning on
relays, or pulsing compressor load or unload
solenoids.
