9. CONFIGURING THE PID
Use this page to configure the PID parameters for both the heating and cooling loops in a Stryker VAV device.
To set PID:
9.1 Fields
Flow Tracking Offset Represents the flow tracking offset value used when FlowType is configured as FlowTracking. This
offset is added to the value of nviFlowTrack to determine the flow setpoint.
Terminal load calculation Enables you to perform the terminal load calculation. You have the option to select 0 or 1 in the
Terminal load calculation field.
Select 0 to use the conventional zone terminal load calculation.
The conventional zone terminal load calculation uses the PID output of heating and cooling
controls. When the controller is switched to the heating mode, the Terminal load is ? 0.
Select 1 to use the CZS zone terminal load calculation.
The CZS zone terminal load calculation uses the proportional output of heating and cooling
controls. When the controller is switched to the heating mode, the Terminal Load continues to
report both heating and cooling demand. The terminal load absolute value is truncated at 100%.
