3 Glossary
The glossary lists all words, abbreviations and technical terminology used in this
manual, along with a short description of these terms.
Term
Description
Auto-run
The outputs to the water valves for basin, shower
and WC can be set to automatically operate at a
set time every day. The water valve will operate
for the cycle set run time as per a user activation.
The Auto-run feature can be used for maintaining
hygiene standards similar to the Inactivity Purge
function detailed below.
Building Management
System
BMS
A Building Management System is a computer
based control system installed in buildings that
controls & monitors the building’s mechanical and
electrical equipment such as ventilation, lighting,
power systems, fire systems, and security
systems.
WDCMS
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 data.
Data Logging
Activations of the Inactivity Purge function
detailed below are logged in memory and then
using additional software the logs can be
downloaded from the WDC200-NX and imported
into a spreadsheet report.
Dual Flush
This option is used when both full and half flush
options must be provided, using either one or two
piezo touch buttons.
Full Flush
This feature uses a 6 litre or 4.5 litre flush.
Reduced & Half Flush
The reduced flush is ⅔ of a full flush and the half
flush is ½ of a full flush.
Inactivity Purge
This feature operates the basin, shower, and WC
water services when they are unused for a
specified number of days. This avoids water
stagnation when the water services are unused
for longer periods.
Latching
A latching switch is a switch that maintains its
state after being activated.

8
WDC200-NX Electronic Water Management.
Revision-2
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 Touch button
A piezoelectric touch button 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 a maximum power to be
used with that device.
Purge Cycle
This feature is used to assist in removing air
trapped in the plumbing system.
Remote Lockouts
The term Remote Lockout refers to isolating
water services from a remote location.
RTC
Real Time Clock. This is a 24-hour 7-day clock
used by the WDC200-NX for program features
such as Time Slots and Inactivity Purge.
System Test
The System Test is a feature that allows you to
operate switches and piezo touch buttons 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 pre-set time
slots. For example, this feature can be used to
prevent all the showers in a facility being
operated simultaneously during peak periods,
straining the capacity of the water supply. 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
Water Lockout means regulating water services
by restricting the number of usage cycles.

4 Product summary
The WDC200-NX electronic control units are designed to operate up to 8x water
valves for wash basins, showers, and the WC flush. The WDC200-NX will typically
manage 2x rooms of sanitaryware (2x WC, 2x basin, 2x shower) although can be
configured to support any mix of inputs / outputs.
The WDC200-NX can be configured to manage other water devices (baths, taps,
etc.) All outputs are freely configurable, up to 8x water valves can be managed by a
single WDC200-NX.
The WDC200-NX will support the connection of additional ‘modules’ to expand the
functionality of the device- see below:
The control unit comprises of a microprocessor that is programmed with a
configurable software program that has the following operational features, note the
controllers can be part of a networked system or stand-alone devices:
•User friendly Software menu system with security-controlled access.
•Independent control of multiple outlets.
•Fully configurable precise time control of water valve operation that is
fully adjustable in situ by the installer / customer.
•‘Lockout’ functions to prevent product misuse that is fully adjustable for
the number of user operations, operations period, lockout period.
•Single or dual flush for WC control.
•Piezo touch button, infrared sensor or tactile capable inputs.
•Auxiliary inputs for remote operation of:
•Remote lockouts.
•WC remote flush.
•Clear lockouts.
•Commissioning Purge function.
•Diagnostic test configuration file to assist with fault finding.
•Fault reporting (requires additional sensors)
•LAN Networking units to remotely control Front End or BMS
•Data logging of hygiene purges and operations
•A scalable system by connecting additional ‘modules’ via CAN Bus,
including:
•240v management for room power & lighting control
•Temperature & Flow Monitoring
•I/O expansion module (additional input & outputs- configurable)
•Bluetooth capability for remote activation of connected utilities, settings
adjustments, and log retrieval

5 Installation and Commissioning
5.1 Package Contents
Before beginning the installation, make sure that you have the following items:
✓1 WDC200-NX Electronic control unit
✓Suitable fixings
✓1 Product manual.
5.2 Advice on attaching the unit
•Attach the unit to a vertical surface that is able to support the weight of
the unit.
•Attach the unit in dry surroundings above pipes carrying water, away
from any possible plumbing leaks.
•Attach the electronic control unit where there is easy access. Attach the
unit so that the keypad and display on the unit are readily visible and
accessible.
WARNING! Do not mount the unit upside down
The control box has four holes for attaching the unit to the wall using four round head
screws.
5.3 Connections
•All cables must be connected to the unit using the sockets at the
bottom of the unit enclosure.
•Piezo / IR input cables, solenoid valve output cables and all CAN / LAN
connections are plug and play fittings with pre-made terminations. All
cabling available from Wallgate at suitable cable lengths.
•The control unit requires an electrical supply of 110-230V AC (Fuse 2
Amp) 50Hz 60 Watts.
•Position all electrical fittings such that water cannot drip on the
electrical fittings if a leak occurs, or a pipe bursts.
NOTE: When mounting the unit, make sure the cable sockets at the bottom of
the unit point downwards.
