Unitary Equipment Controller
The Unitary Equipment Controller (UEC) is a BACnet MS/TP only controller (TC-16/24
hardware platform). Although intended primarily to be connected as an FLN device
(shipped from the factory in FLNnode mode), the UEC can be switched to run in
ALNnode mode and connected as an MS/TP ALN device. In which case the UEC
behaves like an ALN device.
● The UEC can reference external objects using either Device Specific Name or
BACnet Encoded Name.
● Functionality of the UEC Ethernet port is limited to Telnet and FTP.
NOTE: Newer models do not support Ethernet ports.
● The UEC supports the PXM10S and PXM10T controller mounted operator display
modules.
● The UEC does not support HOA modules (PXA8-M, PXA16-M, PXA16-MR).
● Scheduling, trending, and alarming are limited to local objects. The following
BIBBS are not supported:
– AE-N-E-B (External Algorithmic Alarming)
– T-VMT-E-B (External Trend)
– SCHED-E-B (External Schedule)
NOTE:
If a Host/Supervisory field panel references a UEC subpoint, the Host panel must be
upgraded to Firmware Revision 3.2.2 or later.
