Parameters
7.8.1.2.1 Output A
Options:
This parameter defines the type of use of valve output A.
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.
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.
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.
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.

7.8.1.2.1.1 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.
Activated
Deactivated
Use as VAV damper output
