Uninterruptable Power Supply
The WCCIII-MCD2 system is designed to automatically restart
after a power failure. However, the industrial computer which
acts as the WCC III-MCD2 Master Communications Device will
not automatically reboot unless the power is shut off cleanly and
then restored cleanly. During most power outages, the incoming
115 AC voltage could have great fl uctuations before the power
fi nally fails. In a like manner, brownouts will usually cause the
industrial computer to “lock-up.” That is to say, the screen will
continue to display on the monitor, but the cursor will not respond
to the keyboard commands. To prevent this “lock-up” issue from
happening to the WCC III-MCD2, an Uninterruptible Power
Supply (UPS) is required on each and every WCCIII-MCD2
computer.
An Uninterruptible Power Supply (UPS) provides emergency
power to keep the WCC III-MCD2 Master Communications
Device (personal computer) on-line for several minutes after a
primary power failure. The UPS regulates the incoming power
to the computer and shuts the power off cleanly several seconds
after the power outage, or brownout. When the primary power
is restored, the UPS brings the WCCIII-MCD2 back on-line
automatically. The WCC III system does not lose any information
since all of the programs and user entered data are stored on either
a disk in the MCD, on fi rmware, or on battery backed memory in
the satellite controllers.

System Requirements
Software Updates
WCC III-MCD2 program updates will be made available using
USB “jump” drives and/or internet downloading.
NOTE: As of September 1, 2009, all WCCIII-MCDs will only
be shipped with the Linux operating system installed. Older
Windows XP-based WCCIII-MCDs should be upgraded for
any future support issues from WattMaster. The Windows
XP operating system is at the end of long term support with
Microsoft. Microsoft’s main issues are with continuous
updates, and the multitude of viruses that are written for
Windows XP are also of concern. The Linux operating system
software on the WCCIII-MCD2 must be maintained and
updated periodically. WattMaster Controls, Inc. can do these
software updates and upgrades remotely via the internet only
if the WCCIII-MCD is connected to the internet. This is why
internet access to the WCCIII-MCD2 is so important. Failure
to keep the operating system updated could result in a WCC
III-MCD2 system malfunction. WattMaster Controls, Inc. is
not responsible for a system failure that is so generated due to
lack of upgrading or updating because the end customer does
not provide a static IP connection for the WCC III - MCD2 to
the internet for WattMaster Controls to connect to.
WCCIII-MCD2 Internet Access
The most common question asked is: Why does the WCCIII-
MCD2 computer need to have Internet access?
•
If WattMaster Controls factory assistance or
troubleshooting is required for a WCC III system,
a representative from the factory can access the
system with a remote computer and view the same
WCC III Screens as the end user or contractor
in the building. This allows the end user or the
contractor for the building installation to talk to the
factory representative while they are both viewing
the same screens.
•
The Emailing of important alarm notifi cations for
up to 60 Email Addresses is provided for from the
WCCIII-MCD2 device.
•
The ability to send alarm notifi cation via a text
message to a cellular phone.
•
Secure Remote communications package (WCC
III software) is provided for FREE. A CD-ROM is
supplied for installation.
•
World-wide, multiple remote connections (up to
255 simultaneous connections possible)
•
The ability for internet based tenant override
requires internet access.
