Change of value, COV

Change of value, COV defines the change in the value for room temperature that triggers the sending of the value for room temperature.

Range: 0.1...100 [K]

Fan speed actuator (FSA)

Property	Description	Default value
Number of stages	Number of stages defines the number of stages in a fan with staged speed control. Range: 1…3	3
Boost time	The motors of some staged fans do not have a sufficiently powerful torque to set the fan in motion at the lowest speed. Therefore, multi-speed fans are started at the highest speed and then switched back to fan speed 1. Boost time defines the time the motor runs at the highest speed before it is switched back to fan speed 1. Range: 0…50 [0.1 s]	20
Backup mode	Backup mode defines the behavior of the fan speed actuator if the timeout for receiving a Fan speed setpoint or a value for OnOffCtrlFan has passed. Mode 0: The actuator is set to the value defined in Backup value. Mode 1: The actuator returns to the last valid value. Mode 2: The actuator is switched off.	Mode 1
Backup value	Backup value defines the value of the fan speed actuator if the timeout for receiving a Fan speed setpoint or a value for OnOffCtrlFan has passed. The value is only relevant if the property Backup mode is set to Backup value. Range: 1…100 [%]	1

HVAC valve actuator (HVA)

Property	Description	Default value
Neutral zone	Positioning Neutral Zone (0…100%) If the difference between the stroke model and the process value (DY) is more than half the deadband plus the hysteresis, this generates an OPEN or CLOSE pulse which is long enough to return the actuator to a position within the deadband. The minimum pulse length is equal to Rise time or Fall time, multiplied by the hysteresis. (See figure Hysteresis and Neutral zone below). This property is only meaningful if the property Signal type is set to 3-position. Range: 0...100 [%]	0
Maximum pulse rate	Maximum pulse rate defines the pulse rate for a process value of 100 %. This property is only meaningful if the property Signal type is set to PWM constant period. Range: 0...100 [%]	80
Start synchronization	Start synchronization defines the method for synchronization of the actuator’s stroke model at startup. Synchronization is automatically initiated at start up. This property is only meaningful if the property Signal type is set to 3-position. StartSynchronization 1: None StartSynchronization 2: Single Close (CLOSE command during 1.5 x FallTime) StartSynchronization 3: Single Open (OPEN- command during 1.5 x RiseTime)	StartSynchronization 1
Backup value	Backup value defines the actuator position if the timeout for receiving a setpoint for the actuator position has passed. The value is only relevant if the property Backup mode is set to Mode 0. Range: 0...100 [%]	0
Backup mode	Backup mode defines the behavior of the HVAC valve actuator if the timeout for receiving a setpoint for the actuator position has passed. Mode 0: The actuator goes to the value defined in the property Backup value. Mode 1: The actuator keeps the last valid value. Mode 2: The actuator goes to 0 V in case OutLevel0Percent >0.	Mode 1
Signal type	Signal type defines the type of valve that is controlled by the actuator: None 3-position PWM constant period PWM variable period	None
Rise time from 0 to 100%	Rise time from 0 to 100% defines the time needed for the valve to travel from 0 [%] to 100 [%]. This property is only meaningful if the property Signal type is set to 3-position. Range: 0…360 [s]	150
Fall time from 100 to 0 %	Fall time from 100 to 0% defines the time needed for the valve to travel from 100 [%] to 0 [%]. This property is only meaningful if the property Signal type is set to 3-position. Range: 0…360 [s]	150
Polarity inverse	Polarity inverse logic defines if the connected physical output is handled as normally open or normally closed. : The connected physical output is handled as normally closed. : The connected physical output is handled as normally opened.	: The connected physical output is handled as normally closed.
Reaction time	Reaction time defines the additional runtime when traveling to 0 % or from 0 %. The reaction time compensates for the clearance between motor and drive. Note: The internal stroke model is not changed during the reaction time. This property is only meaningful if the property Signal type is set to 3-position. Range: 0…360 [s]	0
Minimum period	Minimum period defines the length of the superordinate period for thermal actuators. This property is only meaningful if the property Signal type is set to PWM variable period. Example for a process value of 60 % and a Minimum period of 400 [s]. - Maximum pulse rate (e.g. 50%) with a fixed period of 1 s during 240 s. - Minimum pulse rate (e.g. 5%) with a fixed period of 1 s during 160 s. Range: 0…32767 [s]	400
Minimum pulse rate	Minimum pulse rate defines the pulse rate for a process value of 0 %. Pulse rate to preheat a thermal actuator. This property is only meaningful if the property Signal type is set to PWM variable period. Range: 0...100 [%]	0
Pulse period	Pulse period defines the length of a switching cycle. This property is only meaningful if the property Signal type is set to PWM constant period. Range: 0…32767 [s]	1800
Hysteresis	Hysteresis in the stroke model This property is only meaningful if the property Signal type is set to 3-position. Range: 0…100 [%]	0
