Display Units: %

CLG-ABSERROR (Cooling Absolute EWMA Error)

 

Provides an EWMA based on the absolute value of (Cooling Setpoint - Process Variable). The PID computes this value.

0.0

Display Units: °C, °F

CLG-ERROR (Cooling EWMA Error)

 

Provides an EWMA based on the difference of (Cooling Setpoint - Process Variable). The PID computes this value.

0.0

Display Units: °C, °F

CLG-EWMA (Cooling EWMA Present Value)

 

Provides an EWMA of the Present Value. The PID computes this value.
