Term Building Management System BMS WDCMS Dual Flush Exclusivity Full Flush Half Flush Hygiene Purge Latching Lockout Momentary Piezo Pushbutton Power Rating Description 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 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. This option is used when both full and half flush options must be provided, using either one or two pushbuttons. This feature prevents more than one water outlet from being operated at a time. This feature uses a 6 or 4.5 litre flush. This feature uses half the quantity of water delivered by a full flush. This feature operates services unused for a specified number of days. This avoids water stagnation when the services are unused for longer periods. A latching switch is a switch that maintains its state after being activated. The term Lockout refers to regulating services by restricting the number of usage cycles. A momentary switch returns to its normal OFF position when released. A piezoelectric pushbutton converts the force applied to the face of the pushbutton into an electrical signal. The power rating of a device is a guideline set by the manufacturer as the maximum power to be supplied to that device. 7 Revision 3.0

8 Term Purge Cycle Remote Lockouts RJ45 connection RTC System Test Time Slots Toggle type switch Water Lockouts Description This feature is used to help remove air trapped in the plumbing system. The term Remote Lockout refers to isolating water services from a remote location. The RJ-45 connector is used for connecting the WDC unit to a PC or laptop. 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. 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. 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 A toggle switch is a class of electrical switches that are actuated by a mechanical lever, handle, or rocking mechanism. The term Water Lockout refers to regulating water services by restricting the number of usage cycles. 8 Revision 3.0

9 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. 9 Revision 3.0

10 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. 10 Revision 3.0

30 The Lockout function is used to prevent misuse of the sanitary facilities. The function is used to limit the number of operations of any valve within a specified time period. When the Lockout function is enabled, the hot and cold basin outlet can be operated for a maximum of 5 times each (total 10 times) over a 1 hour period, the shower 4 times over a 1 hour period and the WC 4 times over a 15 minute period. When the maximum permitted number of operations for any valve is exceeded the valve is locked out (inoperable) for one hour in case of the basin and showers and 15 minutes for the WC flush valve. This setting can be enabled or disabled and is factory set to Disabled. Refer to Table 5 on page 32 for more information on the Lockout function. You can adjust the period of operation for each function such as the basin, shower and WC. The WDC400 electronic control unit cannot control the water temperature for basins or showers. 30 Revision 3.0
