kitControl-SetpointLoadShed

This component provides a convenient way to implement load shedding strategies. It causes a specified setpoint to be raised or lowered by a specific amount in response to an input link, that enables the SetpointLoadShed component. Generally, this component solves the problem often found in temperature control sequences where shutting down an output directly may be complicated by other control dependencies. By changing the setpoint based on a shed request, the control sequence directs the output when to shut down and maintains the interdependencies.

SetpointLoadShed is available in the Energy folder of the kitControl palette.

PropertyValueDescription
Enabledtrue (default) or false and null definitionTurns changing the setpoint on and off.

true adjusts the setpoint by the offset value.

false ignores the setpoint.

When null is checked, the value displayed defaults to the incoming value from the device. If you remove the check mark you can configure theIn value.

Setpoint Innumber of degrees of temperature (defaults to 0.0 F) and null definitionDisplays the normal setpoint value to be adjusted by this object.

When null is checked, the value displayed defaults to the incoming value from the device. If you remove the check mark you can configure theIn value.

Htg Offsetsigned (+ or -) number of degrees of temperature (defaults to 6.0 F) and null definitionDefines the amount by which to adjust the setpoint when in heating mode.

When null is checked, the value displayed defaults to the incoming value from the device. If you remove the check mark you can configure theIn value.

Clg Offsetsigned (+ or -) number of degrees of temperature (defaults to 3.0 F) and null definitionDefines the amount by which to adjust the setpoint when in cooling mode.

When null is checked, the value displayed defaults to the incoming value from the device. If you remove the check mark you can configure theIn value.

Mode InStatusEnum (drop-down list) with three options and null definitionSelects the current need: Off, Heat, Cool.

When null is checked, the value displayed defaults to the incoming value from the device. If you remove the check mark you can configure theIn value.

Offset in Effecttrue or false (default) and null definitionIndicates if the Setpoint Out property value has been adjusted.

When null is checked, the value displayed defaults to the incoming value from the device. If you remove the check mark you can configure theIn value.

Setpoint Outnumber of degrees of temperature and null definitionDisplays the adjusted setpoint value, if active, otherwise it passes through to the original setpoint.

When null is checked, the value displayed defaults to the incoming value from the device. If you remove the check mark you can configure theIn value.
