Additional Information and Considerations
If the device should go offline, the communicated value from the front-end Tracer SC will be
released:
Room Temperature
Outdoor Temperature
Occupancy
Device Nameand DeviceID propertiesare writablein BACnetdevice object.Bothproperties can
be renamed from any BACnet network management tool as long as the tool itself give access
to write to these properties.
The BACnet Data Link layer has two key parameters: the device object name and the device
object ID. The device object name must be a unique BACnet device object name within the
BACnet network (i.e. not just the MS/TP sub-network). The device object ID must also be a
unique BACnet device object ID in the entire BACnet network (i.e. not just the MS/TP sub-
network).
The following items apply to fan coils only.
Enumeration sets for System Mode MV16 depends on Sequence of Operation (MV15) value
upon devicediscovery. If required enumerationsare not present,set MV15 to desiredvalue and
rediscover MV16 object. Available enumeration will now reflect required configuration.
Enumeration sets for MV16 depends on Fan Mode Sequence (MV58) value upon device
discovery. If required enumerations are not present, set MV58 to desired value and rediscover
MV16 object. Available enumeration will now reflect required configuration.
Enumeration sets for MV26 and MV27 depend on Control Type (BV75) value and Pipe Number
(MV52) valueupon devicediscovery. Ifrequired enumerationis notpresent, set BV75and MV52
to desired value and rediscover MV26 and BV27 object. Available enumeration will now reflect
required configuration.
To assign manually a Room Temperature (AV7) value, users must first enable the Override
mode in the Room Temp Override (BV8) object.
To assign manually a Room Humidity (AV10) value, users must first enable the Override mode
in the Room Humidity Override (BV11) object.
