Figure 58: Unit Sequence of Operation - Cool Mode (continue)
Keep pump output on while
chiller is enabled and either
running or ready to run.
Is there enough load to
start chiller?
Yes
Start rst circuit.
Maintain unit capacity.
Additional capacity
needed to satisfy load?
Yes
Has the stage up time
delay expired?
Yes
Increase unit capacity.
Unit at full capacity?
Yes
IOM 1206-13 • TRAILBLAZER
No
The chiller is now ready to start if enough load is present. If the LWT is not higher
than the start up temperature, the unit status will be Auto:Wait for load.
If the LWT is higher than the start up temperature, the unit status will become
Auto. A circuit can start at this time.
The rst circuit to start is generally the available circuit with the least number of
starts. This circuit will go through its start sequence at this point.
No
The unit capacity can be increased if the LWT is above the stage up temperature.
No
No
A minimum time must pass between the starting of circuits.
If the second circuit is not running, it will be started now. The unit will try to keep
the load balanced between circuits as the unit capacity is increased.
If both circuits are running, then additional compressors will start based on the
sequencing logic.
