The WCC III - MCD
The WCC III - MCD
Overview
The WCC III – MCD was converted from the Windows XP 
operating system over to the Ubuntu version of Linux using the 
command line interface only and was then released by WattMaster 
Controls in October of 2009. The main function of the WCC 
III – MCD is to provide a hardware and software platform for a 
program that WattMaster Controls has developed that is called 
“BACKTASK.exe”. The BACKTASK.exe program is a multiple 
BACKground TASKing application program.
BACKTASK.EXE (SS5009)
The BACKTASK.exe program performs many functions such 
as: 
•
USB communications to the internal MCOMM board
•
Time clock functions
•
Analog/binary global processing
•
Overrides of control points
• Holiday
scheduling
• Optimal
starts
• PID
programs
•
Shed /Restore programs
•
Duty cycle programs
• Proportional
Programs
• Tenant
Overrides
•
Emailing of alarms
The BACKTASK.exe program also provides for remote IP 
connection to a set of windows-based programs generally referred 
to as the WCC III programs. This WCC III – MCD also has 
hardware (WCCIII MCOMM board) that interfaces to a RS-485 
communications loop that connects to SAT III type controllers for 
building automation controls.
Watchdog Circuit/Power Fail
If the BACKTASK.exe program is not running on the WCCIII 
- MCD, there is a watchdog circuit that will restart the WCCIII 
– MCD. This watchdog circuit may interfere with the installation 
of new BACKTASK.exe software. There is a way to disable this 
watchdog circuit. Please contact WattMaster Controls for further 
information on temporarily disabling this watchdog circuit. In 
addition to this watchdog circuit, there is a small wall wart 24vac 
transformer that must be connected to 120VAC or else the WCCIII 
- MCD will restart every two minutes. This is part of the power fail 
design circuit of the WCC III – MCD. This transformer is meant to 
be plugged into a (NON – UPS) 120VAC outlet. The power cord 
for the WCC III – MCD is to be connected to a dedicated UPS 
(Uninterruptible Power Supply) outlet so that the MCD will keep 
running during a minor power outage. The Cable/DSL modem/
router should also be plugged into one of these dedicated UPS 
(Uninterruptible Power Supply) outlets.
MCD-Menu Program Overview
WattMaster Controls has developed a simple setup installation 
program for the Linux command line interface, and this program 
is called mcd-menu. Prior knowledge of Linux is not required, but 
would be helpful. This mcd-menu program has eleven subprograms 
incorporated into it that will allow for the following operations to 
be preformed: 
•
The setup of the Network IP Confi guration of the 
WCC III – MCD network card interface
•
Copying of the BackTask specifi c data fi les to the root 
of the USB Drive
•
Restoring of the BackTask specifi c data fi les from the 
root of the USB Drive
•
The resetting of the WCC III - MCD IP address back 
to the WattMaster factory Default IP Address settings
•
The resetting of the WCC III - MCD DNS settings 
back to the WattMaster factory default DNS settings
•
The restarting of the 2 by 20 line LCD Driver that is 
located on the front of the WCC III - MCD
•
The restarting of the 2 by 20 line LCD Display that is 
located on the front of the WCC III - MCD
•
The testing of the Internet Connection, from the WCC 
III - MCD to the internet 
•
The testing of DNS Settings, from the WCCIII - MCD 
to the internet
•
The shutdown of the WCC III - MCD – properly 
closing down
•
The shutdown and restart of the WCC III - MCD
The Webmin access method can also accomplish all of these same 
tasks, but is a little bit harder to use and is meant to be more of an 
“off site” management tool for the WCC III - MCD. The mcd-
menu program is meant to be used as the initial IP setting tool and 
BACKTASK data fi le loading tool for the WCC III - MCD. For 
this a monitor and keyboard needs to be connected temporarily just 
for the initial IP setup and BACKTASK data fi le loading.
