Output A
Options:
Activated
Deactivated
Use as VAV damper output
This parameter defines the type of use of valve output A.
Note
The control value is assigned to the valve in the
Application – Application parameters
parameter
window. Here it is defined which control value from the controller is to be output on which valve
output.
•
Activated
: The output is used as a normal control value for a 0 - 10 V valve. The group objects
Status byte valve A
,
Status Control value
,
Fault: valve output A
and
Reset fault on valve output
A
are displayed. The dependent parameters are displayed.
•
Deactivated
: The output is deactivated.
Note
Nevertheless, a control value can still be assigned to the valve in the
Application – Application
parameters
parameter window. Because the output is deactivated, this value is not output.
•
Use as VAV damper output
: With this setting the output is used to operate a damper drive using
the 0-10 V signal. For this purpose the parameters and group objects for the valve output are
deactivated and instead the group objects
Control value VAV damper control A
and
Status
Control value
displayed. The dependent parameters
Voltage range VAV damper control value
and
Reaction on bus voltage recovery, ETS download or ETS reset
are displayed.
Note
Nevertheless, a control value can still be assigned to the output in the
Application – Application
parameters
parameter window. Although this control value is output, it can cause malfunctions
due to the lack of adjustment.
Note
In this mode the output behaves like a normal analog output. The control value received via the
bus is output directly in the selected output range. There is no further influence from the con-
troller.

Dependent Parameter
Valve type
This parameter indicates whether the valve output is a normal output or this output is used to actu-
ate a 6-way valve. This parameter can be changed using the
Use 6-way valve
parameter in the
Application – Application parameters
parameter window.
•
Normal
: This option is set if the
Use 6-way valve
is parameterized with the
No
option.
•
6-way valve
: This option is set if the
Use 6-way valve
is parameterized with the
Yes
option.
