SterlingTek A0551797 User Manual

1.  The system uses a PID control algorithm to regulate the 

chilled water temperature.  As the required control effort 
increases or decreases, the system compressors are turned 
on or off to keep the temperature at the specified set-point 

2.  Compressor anti-recycle time is three (3) minutes. 

 

 

If a fault occurs, that compressor or circuit is deactivated.  The 
load will automatically shift to any other compressors that are 
currently ON-LINE, but not running.  Lead/Lag rotation will 
continue to function.  Compressors that are faulted will be 
removed from the rotation order. 

 

 

The system automatically rotates the compressor order to generate 
a Lead/Lag rotation.  Any time a compressor is faulted or manually 
taken OFF-LINE, it will be removed from the Lead/Lag rotation.  
Once the fault is cleared or manually put ON-LINE, the 
compressor is returned to the Lead/Lag rotation at the end of the 
rotation order.

 

 

The system automatically rotates the pump order to generate a 
Lead/Lag rotation.  Any time a pump is faulted or manually taken 
OFF-LINE, it will be removed from the Lead/Lag rotation.  Once 
the fault is cleared or manually put ON-LINE, the pump is returned 
to the Lead/Lag rotation at the end of the rotation order.
