Veterans Medical Center Northport
Long Island, NY
Optima
Controls, Ltd. designed and installed an Energy Management and Control
System (EMCS) utilizing a combination of Direct Digital Controls (DDC) and
pneumatic controls for the facilities temperature control system using
Teletrol System, Inc. equipment.
The
system is installed in the campus’s main chilled water plant, 2 patient
housing buildings, 2 outpatient service buildings and the new patient
clinical facility.
The
EMCS is comprised of 36 primary nodes consisting of Integrator186, AHC186
and IntegratorCS controllers with 37 ValuTRAC Controllers and 45 TSC
controllers comprising of over 2000 physical points controlling.
Completed a 5 year service contract in September 2000 and it was
renewed for an additional 5 years.

computer on the facility LAN.
-
Long
term customer relationship continuing with maintenance service and
building renovations
The
control program for the air handlers provide the building engineers with
vital information such as point history samples, differential static
pressure of the filters, fan status alarming and user changeable control
set points. The air handlers operate continuously to maintain either a
constant discharge temperature for the VAV systems or an adjus table space
temperature.
The
graphical interface was developed using Teletrol Systems, Inc., Panorama
software. From the graphical interface the user can get instantaneous
point data and have full control through the following graphics:
