SECTION 5: COMMUNICATIONS

One ROBERTS GORDON
ing Heating Control per building (called the "central
controller") comes standard with a touchscreen. The
central controller communicates with all satellite con-
trollers, and COMPLETE™ unitary controllers when
applicable. More than one "central" controller can be
used, if desired. If multiple CORAYVAC
Heating Control controllers are being used, the addi-
tional controllers communicate to controller #1
through communication wiring arranged in series
from one controller to the next. See Page 39, Section
5.3. An MS/TP network can be in a daisy-chain or
hybrid configuration if repeaters are used as
described in MS/TP network requirements. Each net-
work segment must be in a daisy-chain configuration.
See Page 16, Section 3.4.2.

5.1 WebCTRL

®
The WebCTRL building automation system offers an
intuitive user interface and powerful tools to help
facility managers keep occupants comfortable, man-
age energy conservation, identify key operational
problems and analyze the results. The optional
WebCTRL ® package allows direct communication via
on-site or remote off-site control to the central con-
troller. WebCTRL ® is an automation system interface
through (HTTP) to communicate over the internet or
®
Ethernet. WebCTRL provides complete access to
all touchscreen features that include but are not lim-
ited to:
• Setting and changing schedules
• Adjusting setpoints and other control properties
• Graphically trending building conditions
• Viewing and acknowledging alarms
• Custom alarm management capabilities to allow
notifications via e-mail, text messaging, etc. for
situations such as when zone temperatures drop
below setpoints or exceed user-defined require-
ments.
• Graphical representation of system(s) status.
• A WebCTRL ® license is issued and software
installed on one computer on network. DIP switch
