6.1.2 System description
6.1.2.1 Distributed system
CSNET WEB is an independent centralised control system which can control an H-LINK communication line. When it is
connected to a system with Packaged units, it can control up to 160 indoor units and 64 outdoor units.
CSNET WEB connects to a Local Area Network or Internet (using a DSL Router) by means of its Ethernet port, so that the
parameters can be adjusted and monitored at a distance.
The internal memory for adjustments to the timer and the units allows CSNET WEB to perform independently after initial
adjustment through a personal computer or similar device.
CSNET WEB does not need a dedicated computer to operate.
The physical device (hardware) of CSNET WEB is called PSC-A160WEB1.
