____________________________________________________
The ECC/WCC II is a microprocessor based energy management
and temperature control system designed to minimize the energy
usage of a building and maximize the occupant comfort.The ECC/
WCC II system provides the building owner with a means of
monitoring and controlling building mechanical systems from one
central location. The ECC/WCC II system provides computerized
control of building mechanical systems, but requires no computer
experience to operate or program the system.
Diagram of WCCII System
The “front end” of the ECC/WCC II system consists of a personal
computer with custom communication boards. See Diagram that
follows. The computer is referred to as the Central Processing
Unit (CPU), and the computer, keyboard, monitor (screen), printer
(optional), and modem (optional) together are referred to as the
Operator Control Console. The CPU communicates with the
remote satellite controllers using a two-wire communication loop.
