The glossary lists all words, abbreviations and technical terminology used in this manual, along with a
short description of these terms.

Description
Building Management
System
BMS
WDCMS
A Building Management System is a computer-based control
system installed in buildings that controls and monitors the
building’s mechanical and electrical equipment such as
ventilation, lighting, power systems, fire systems, and
security systems.
The WDCMS Wallgate system is used for standalone
networking of the WDC control units to a dedicated PC or
laptop computer. You can manage the WDC units through
the network. You can also adjust time cycle settings, lockout
settings, remote water isolation on individual units or groups,
RTC settings, etc. You can also view the unit status in real
time and log the data.
Dual Flush
This option is used when both full and half flush options must
be provided, using either one or two pushbuttons.
Exclusivity
This feature prevents more than one water outlet from being
operated at a time.
Full Flush
This feature uses a 6 or 4.5 litre flush.
Half Flush
This feature uses half the quantity of water delivered by a full
flush.
Hygiene Purge
This feature operates services unused for a specified number
of days. This avoids water stagnation when the services are
unused for longer periods.
Latching
A latching switch is a switch that maintains its state after
being activated.
Lockout
The term Lockout refers to regulating services by restricting
the number of usage cycles.
Momentary
A momentary switch returns to its normal OFF position when
released.
Piezo Pushbutton
A piezoelectric pushbutton converts the force applied to the
face of the pushbutton into an electrical signal.
Power Rating
The power rating of a device is a guideline set by the
manufacturer as the maximum power to be supplied to that
device.

Description
Purge Cycle
This feature is used to help remove air trapped in the
plumbing system.
Remote Lockouts
The term Remote Lockout refers to isolating water services
from a remote location.
RJ45 connection
The RJ-45 connector is used for connecting the WDC unit to a
PC or laptop.
RTC
Real Time Clock. This is a 24 hour 7 day clock used by the
WDC400 for program features such as Time Slots and
Hygiene Purge.
System Test
The System Test is a feature that allows you to operate
switches and pushbuttons and make sure that these operate
the necessary outputs such as lights or valve solenoids.
Time Slots
Usage of services such as basins, showers and WC pans can
be controlled using preset time slots. For example, this
feature can be used to prevent all the showers in a facility
being operated simultaneously during peak periods, which
can lead to lack of water shortage. The day is divided into 4
time slots, normally set at 00:00 to 06:00, 06:00 to 12:00,
12:00 to 18:00 and 18:00 to 00.00.
Toggle type switch
A toggle switch is a class of electrical switches that are
actuated by a mechanical lever, handle, or rocking
mechanism.
Water Lockouts
The term Water Lockout refers to regulating water services
by restricting the number of usage cycles.

4.System Overview
The WDC400 series control unit consists of a sheet steel enclosure that houses the
electronic control circuitry behind a hinged, lockable door. The circuitry contains relays and
mains power connection terminals.
You can safely operate the electrical isolator and circuit breakers from outside the housing.
The following devices are also located outside the enclosure:
User interface.
Visual display.
Low voltage control inputs.
Outputs at 12 V DC.
The control unit requires 230 V AC single phase electrical supply and is designed for wall
mounting. Refer to Table 3 for the technical specifications of the WDC400 control unit.
The control unit manages the delivery of water in 2 cells/rooms to:
Warm and cold water feeds for hand wash basins.
Premixed warm water for showers.
Cold water feed for WC full or half flush.
The control unit can:
Control the electrical supply to the sockets in each individual cell or room.
Switch the cell/room lighting on or off.
Switch the cell/room lighting on or off individually to vary the lighting levels.
Control the cell/room lighting using timers to conserve energy.
Remotely control the water services.
Control the services that the occupant of the cell or room can use.

The standard unit is preset at the factory with default settings. You can change these
settings as necessary to deliver customised cell or room services. All the programming is
done through the keypad on the front panel, or through a PC workstation over the network
link.
As all the settings are retained in non volatile memory, the settings are not lost if the power
supply to the unit is disconnected. Customised settings from one unit can be easily copied to
other units using a PC workstation over the network link.
The electronic water management and Lockout features are designed to conserve water
and prevent misuse of the water services. The user interface is structured to ensure each
control valve has independent control and can be easily adjusted and viewed on the
illuminated display.
The user operates Piezo pushbuttons or infra red hand sensors to open and shut the water
supply to various services such as the basin, shower and WC. The cell/room lights are
controlled by either momentary or latching toggle/rocker switches. You can manage the
control unit in real time through a PC connected to the network (Comms) sockets.
