Why does the
slave
window contact/occupancy contact
have no effect?
The slave window contact can only be integrated via the CFC.
The corresponding compound is available on Swan Web: [WndStaDtr], [OcStaDtr].
For one slave controller:
Create group addresses for window contact and add communication object of master
and slave.
For one ore several slave controllers:
In CFC by means of compound [WndStaDtr], [OcStaDtr].
Why does the
ACS plant graphic
not always display all values (e.g. room operating
mode)?
The controller is configured as a slave. These values are not available with slave
controllers.
Why doesn’t the
ACS operator book
show the current data?
After a change of application (e.g. from FNC12 to FNC18), you must update the
reference data points.
ACS
: CLC01 shows the lower limit of 21°C for the Comfort cooling setpoint.
Setpoint data are only updated when the application (RAD01, CLC01, ...) has been
selected.
Why doesn't an RXB controller transmit S-Mode communication objects that it has
received?
RXB controller do not work as bus relays
.
If a communication object is required, the binding must be to the source, not to the RXB
controller.
Example: an RXB controller receives the room temperature from a bus sensor.
A bus display is used to display the room temperature.
Æ
The display must get the signal directly from the bus sensor.
