Air Flow Measurement Specifications
Range 0 to 2.0" wc
Accuracy @ low flow (0.008" wc to 0.01" wc)
±3.5%
Accuracy @ high flow (0.01" wc to 2.0" wc)
±2.0%
Maximum distance of the LRC from the air
velocity sensor
50ft (12.2m)
Lab Room Controller Communication
Up to 32 LRCs or other Terminal Equipment
Controllers can be connected to each of a field
panel’s 3 FLN trunks for a total of 96 per field panel.
Communication with the LRC can be initiated from
any APOGEE Automation System field panel on the
system network. The APOGEE Automation System
network does not require additional hardware to
connect Terminal Equipment Controllers. When
Terminal Equipment Controllers are wired to a field
panel, features such as energy management
programs, alarm reporting, centralized control,
modification of the system database, system-wide
troubleshooting and the global commanding of
devices are available to them.

Portable Operator’s TerminalPortable Operator’s Terminal
Portable Operator’s Terminal
The computer serving as the Portable Operator’s
Terminal can communicate with LRCs or any field
panel. The terminal connects to the controller via a
plug-in jack on either the controller, the room
temperature sensor associated with the LRC, or a
field panel. The terminal can be used to remotely
adjust air volume settings or temperature set points,
to troubleshoot, and to start up the system. When
connected to the RS-232 port of a field panel, the
terminal provides system-wide communication. The
terminal uses full English language for all functions,
eliminating the need to remember coded commands.
