Type

Description

Active Cool Setpoint

Numeric

This property indicates the resultant cool setpoint presently in use by the UCM.

Active Heat Setpoint

Numeric

This property indicates the resultant heating setpoint presently in use by the UCM.

Active Min Flow Setpoint

Numeric

This property indicates the minimum flow setpoint presently in use by the UCM. When the VAV is in pressure dependent operation (i.e. it’s using ‘positional control’), this property represents a valve position (percent open). Otherwise, it represents a percentage of nominal flow size.

Air Flow Stpt: Active Min

Numeric

When the VAV is in pressure independent operation, this property indicates the minimum flow setpoint presently in use by the UCM. In pressure independent operation, the minimum flow setpoint will either be the "Air Flow Stpt: Min Cool" setpoint, the "Air Flow Stpt: Min Heat" setpoint or the "Air Flow Stpt: Min Local Heat." Which of the three aforementioned properties turns out to be the active one is determined by the UCM.

When the VAV is in pressure dependent operation (i.e. it’s using ‘positional control’), this property will not accurately reflect the setpoint presently in use by the UCM.

This property has dimensionality of gaseous flow.

Air Flow Stpt: Max

Numeric

When the VAV is in pressure independent operation, this property indicates the maximum flow setpoint presently in use by the UCM.

This property has dimensionality of gaseous flow.
