6.2 Engineering
6.2.1 KNX S-mode engineering
The VAV compact controllers are certified KNX devices. For engineering and
commissioning, the ETS software is used. The parameters and S-mode datapoints
are documented in chapter Fehler! Verweisquelle konnte nicht gefunden werden..
The required product data (*.vd5 or *.knxprod) can be downloaded from the
Siemens website and imported into the ETS device catalog. To obtain the product
data, navigate to www.siemens.com/hvac-td or www.siemens.com/openair and
locate the “Downloads” section.
6.2.2 KNX LTE-mode / Synco 700 engineering
Engineering in KNX LTE-mode environments (Synco 700) is performed with the
tool ACS790 [8].
During mounting of the VAV compact controllers, the address labels can be
removed from the devices and attached to e.g. the building/floor plan to map KNX-
IDs and physical location of the devices.
After mounting and installation is completed, the installed devices are found when
the ACS790 device list is refreshed. In the device list, the collected IDs can be
used to identify the devices and to assign physical addresses according to the
intended plant topology. With this approach, commissioning can be done without
much effort. For an alternative commissioning procedure, cf. section 6.3.3.
Plants with supply air and extract air control in KNX LTE-mode environments with
Synco 700 must be realized as a Master/Slave configuration (cf. section 5.3.4). All
devices have to be in the same air distribution zone which has to be set to “8” in
Synco 700 systems.
The Slave-VAV compact controller’s air volume flow limits (V
min
and V
max
) have to
be set to 0 % and 100 %. The VAV compact controllers have to be configured as
Master and Slave in ACS790 (in “Plant engineering”, navigate to VAV compact
controller / “Operation settings”).
The Master-VAV compact controller must be associated with “Supply air”, and the
Slave-VAV compact controller must be associated with “Extract air”.
