Control Center Screens shown may NOT represent the exact screens according to the software version utilized.

overvieW

This screen displays the present tuning parameters used

by the Leaving Chilled Liquid Temperature, Evapora-

tor Pressure, Condenser Pressure, Hotwell Level, and

Subcooler Level PID controllers. Each of the control-

ler boxes displays the input process variable

(PV)

that

is being controlled as well as the controller output sig-

nal

(CV)

that repositions the controlled device to main-

tain the process variable at setpoint

(SP)

. The response

time of each controller is determined by the Propor-

tional

(P)

, Integral

(I)

, and Derivative

(D)

tuning set-

points entered. In some cases, different tuning parame-

ters must be entered to match the process response time

depending on the controlled device. The black text to

the right of the data fields changes to

SPD

PRV

, or

HgV

depending on the mode selected with the

Select

Control

key. In some cases, a setpoint ramp rate

(RR)

is also available. All setpoints require a login access

level of Service or higher. Service Technicians refer to

YORK Service Manual 160.67-M3 for operation and a

detailed explanation of the tuning parameters.
To view the results of a setpoint change, the applicable

Screen name is also referenced.

This box displays parameters pertinent to the Leaving

Chilled Liquid Controller used to maintain the liquid

temperature (PV) at the setpoint (SP). The setpoint of

this controller is changed locally on the Setpoints Screen

or remotely via one of the available remote setpoint op-

tions. The output (CV) displayed will decrease to un-

load the chiller if the Leaving Chilled Liquid Tempera-

ture is below the Setpoint. The setpoint ramp rate (RR)

determines the rate at which the setpoint ramps to a

new value. The black text to the right of the data fields

changes to SPD, PRV, or HGV depending on the mode

selected with the Select Control key. The green Active

text changes to yellow Inactive text to display if the

controller is presently controlling the chiller capacity.
