Features
M odular hardw are components to match
equipment to initial control requirements w hile
providing for future expansion
M odular, snap-in design simplifies installation and
servicing
Transparent view ing panels on the enclosure door
to view the status indicator LEDs and override
sw itch positions
Integration platform for communications and
interoperability w ith other systems and devices

Description
The M odular Building Controller (M BC) is an integral
part of the APOGEE® Building Automation System.
It is a high performance, modular Direct Digital
Control (DDC) supervisory field panel. The field panel
operates stand-alone or netw orked to perform
complex control, monitoring and energy
management functions w ithout relying on a higher
level processor.
The M BC provides central monitoring and control for
distributed Floor Level Netw ork (FLN) devices and
other building systems (e.g., chiller, boiler, fire/life
Advanced Proportional Integral Derivative (PID)
loop tuning algorithm for HVAC control to
minimize oscillations and guarantee precise
control
Built-in energy management applications and DDC
programs for complete facility management
Modem
Comprehensive alarm management, historical data
trend collection, operator control and monitoring
functions
Support for peer-to-peer communications over
Industry standard 10/100 Base-T TCP/IP netw orks.
