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 Hygiene Purge
function detailed below, note that only the Auto-run
or Hygiene Purge would be utilized, and not both
together.
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 use 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 Hygiene Purge function detailed
below are logged in memory and then using
additional software the logs can be downloaded
from the WDC100 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.
Exclusivity
This feature prevents more than one water outlet
from being operated at a time.
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.
Hygiene 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.

Term
Description
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 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.
RJ45 connection
The RJ-45 connectors are used to connect the
WDC unit to a PC or laptop.
RTC
Real Time Clock. This is a 24 hour 7 day clock
used by the WDC100 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 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 preset 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 WDC100 series electronic control units are designed to operate the water outlets
(x1) (Hot and Cold), to a wash basin (or a bath model WDC100-1), a shower (x1)
(premixed warm water) and the flush for toilet water closet pan (x1) (WC).
The WDC100 therefore has the capacity to control one suite of products.
The WDC100-1 model is preset to operate the water outlets on a bath instead of a
wash basin.
The WDCA100 model based upon the WDC100 is for 120V 60Hz electrical supply
operation using an external power adapter (UL/CSA approved) to connect to the
12VDC input socket on the WDCA200 control unit.
The control unit comprises of a microprocessor that is programmed with a software
program that has the following operational features:
User friendly Software menu system with security controlled access.
Independent control of multiple outlets.
Fully programmable precise time control of water valve operation that is fully
adjustable in situ by the installer / customer.
“LOCKOUT” function to prevent product misuse that is fully adjustable for the
number of user operations, operations period, lockout period, and the
“LOCKOUT” function can be ENABLED or DISABLED to suit the individual
requirements.
Single or dual flush for WC control.
Piezo touch button or infra-red sensor capable inputs.
Auxiliary inputs for remote operation of:
Product lockouts.
WC remote flush.
WC reduced flush using a second touch button.
Clear lockouts.
Purge function.
Flow sensor for hygiene purge data logging.
Multiple shower control feature (COMMUNAL mode setting), so that one unit can
be used to operate up to four shower valves instead of basins and WC pans.
Diagnostic test routine to assist with fault finding
Networking units to remotely control from a central PC desk position(s).
Data logging of Hygiene Purges.

5. Installation and Commissioning
5.1. Package Contents
Before you begin the installation, make sure that you have the following items:
1 WDC100 Electronic control unit (or WDC100-1 bath model)
1 Product manual.
5.2. Site Preparation
5.2.1. 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 feet with holes for attaching the unit to the wall using four
round head screws, No 8 x 30mm (1.25 inch). For the location of the mounting
feet, refer to Figure 1 on page 10.
5.2.2. Electrical connections
All cables must be connected to the unit using the sockets at the bottom of the
unit enclosure.
The power cable must be connected to the unit through the cable gland.
The control unit requires an electrical supply of 115-230V AC (Fuse 2 amp) 50Hz
60 Watts.
The mains supply cable from the unit must be terminated into a double pole fused
spur connection unit with a contact separation of at least 3mm. Use a 2 Amp fuse
in the connection unit.
Place the connection unit near the controller unit.
Position all electrical fittings such that water cannot drip on the electrical fittings if
a leak occurs, or a pipe bursts.

WARNING! The controller unit must be earthed using the earth lead in the
power cable.
5.3. Attach the Controller Unit
To attach the control unit to the wall, do the following:
1. Mark the attachment points for the control unit on the wall. Make sure the cables
from the solenoid valves and piezo touch buttons are of sufficient length to reach
the control unit. Refer to Figure 3 for the location of the mounting feet.
2. Drill four mounting holes using a suitable drill bit.
3. Use suitable wall plugs if necessary.
4. Attach the unit to the wall using four round head screws.
