TimeDelay_Normal

This property specifies the minimum time in seconds that Present_Value must remain within the range defined by the properties High_Limit and Low_Limit, including the Deadband property, before a TO-NORMAL event is generated.

Please note: up to BACnet revision 12, only Time_Delay was available in the BACnet standard for the two transitions TO_OFFNORMAL and TO_NORMAL. From revision 13, this optional TimeDelay_Normal property is used to specify a separate hysteresis for TO_NORMAL events.
