7.8.1.2.1.1.2.3 Dependent Parameter
Valve drive opening/closing time
Options:
With this parameter, a time is set in seconds that the connected valve requires to move from posi-
tion 0 % (valve closed) to position 100 % (valve fully open), or the valve requires to move from
100 % to 0 %.
The time should be taken from the technical data of the valve, and it corresponds with the total
runtime.
7.8.1.2.1.2 Use as VAV damper output

7.8.1.2.1.2.1 Dependent Parameter
Voltage range VAV damper control value
This parameter is visible if the Use as VAV damper output option has been selected in the Valve
output parameter and the output is used as a valve output.
Options:
This parameter defines the function of the damper control value. Depending on the selection, the
control value is converted to the corresponding voltage range.
On the selection of the 1 - 10 V and 2 - 10 V options, the output voltage is limited to this range. To
make sure that the damper is always closed completely, on the actuation of the output with 0 % (=
closed), the control value 0 V is output nevertheless. If the control value is greater than 0 %, the
lower limit (1 V or 2 V) is used directly for the actuation.
If the DPT 5.001 (percent) is used for the actuation, the value of the group object may be displayed
as 0 %, but the actual value of the group object may be slightly above that and a 0 is only dis-
played due to the rounding to integer values. This situation can be detected by viewing the hexa-
decimal value (this is then e.g. 0x0001) or changing to a different DPT (e.g. 5.005).

7.8.1.2.1.2.2 Dependent Parameter
Behavior after bus voltage recovery, ETS download and ETS reset
Options:
The reaction of the VAV damper output after bus voltage recovery, ETS download and ETS reset
is specified using this parameter.
• Unchanged: If this option is selected, after bus voltage recovery, ETS download and ETS reset
the output provides the same voltage as before the event.
• Select: If this option is selected, it is possible to set the output voltage after bus voltage recov-
ery, ETS download and ETS reset in the Control value parameter.
