Introduction
Thank you for purchasing the W25T Water Controller.
The W25T Water Controller encompasses all the latest features of the vending in-
dustries such as the DEX port and dual cashless MDB port allowing connecting both
a credit/debit card reader and a proprietary prepaid card system in addition to a
bill reader, and of course a coin changer. This allows as well to revalue the prepaid
card using credit card, coins, or bills. It can also work with a coin acceptor only
configuration when giving back change is not required.
The W25T is easy to install and program. This manual covers mainly the program-
ming aspect of the W25T. The large 2x20 LCD display is capable of displaying in
English or French but not both. The entire programming of the W25T is achieved
by using the lighted selection buttons on the selection panel of the machine.
The next pages will guide you step-by-step through the many features of the W25T.
An illustrated flow chart makes navigating through the different parameters a very
easy thing.

Operating principle
The W25T Controller delivers water in two different manners: 1- On a time basis; 2
- On a volume basis.
The time basis is used when the flow of water is continuous and with steady water
pressure. If the flow is not continuous or if the water pressure is not steady, this
will result in inconsistent quantity of water from one delivery to the other. The
only way to ensure a steady volume of water from one delivery to the other is by
using a water flow meter.
The W25T allows the use of the following payment peripherals: Coin acceptor only
(no change given back), coin changer (from a 3-tube up to a 6-tube of change), bill
acceptor, one or two cashless devices (credit/debit, prepaid, RFID, on-line-off-line,
etc.).
The W25T offers 4 different preset water quantities at four different prices. Both
the water level and the price are of course programmable. Once you have inserted
sufficient credit, you can select the format of container you wish to fill. If the vend
price of the chosen format is higher than the amount inserted, the green Start but-
ton will stay OFF. If the vend price of the chosen format is equal or lower than the
amount inserted, the green Start button will activate waiting for the customer to
start filling the container. Once the vend process
starts, the W25T immediately starts giving change
back if needed or concludes the transaction to the
card reader, no matter how long it takes to fill the
container.
The large LCD display prompts a multitude of mes-
sages to the customer such as the vend price, format
chosen, low-change situation, and much more.

Component identification
The image below shows a typical water filling station equipped with our W25T Con-
troller. Yours may differ. On the right side of the machine is the control panel with
its:
A: 2x20 giant LCD display (smaller size display available)
B: Coin insertion slot & coin return button (escrow)
C: Combined bill acceptor & credit/debit card reader
D: Selection buttons
E: Proprietary prepaid magnetic card reader with its own display
Note that elements C and E can have their respective position swapped if needed
and can also be different than those shown here.

Circuit description
The circuit W25T is the brain of the machine. It controls the quantity of water sold,
the vend prices, the different payment peripherals, and keeps track of the sales
done. The W25T is actually two circuit boards mounted on each other. Most of
the wiring of the machine goes to or comes from the W25T.
The lower board is part number A09860.
The piggyback expansion board is part number A09870.
One cannot work without the other.

Navigating in the program
Navigating in the program, be it the different settings or the audit, is done using the
selection buttons in front of the machine. This manual was written using a machine
equipped with four buttons (F, S, P, R). Some machines may have only two buttons.
In such a case, the programming is done using the square buttons located on the
W25T circuit board.
In any case, accessing the different settings and information is done using the
BLACK push button ON THE CIRCUIT inside the machine (see image pages 5 & 6).
Once in, you then use the selection buttons to navigate.
There are two (e) different menus which are:
Operator menu
Technician menu
If you are the owner of the machine and do not want your employees to access the
Technician menu, keep this manual in an inaccessible place as the following pages
indicates how to access this menu.
The Operator menu divides in three sub-sections which are:
Audit: Gives you the entire monetary activities of the
the machine.
Currency Settings: This is where you will decide what are the coins
and bills you accept.
Vend Price Settings: This is where you will set the four potential
vend prices.
The Technician menu consists of:
System settings: Allows for setting the multiple parameters of
the machine.

The Audit
The W25T offers a full audit of the transactions done by the machine plus the cur-
rent state of the tubes inventory. The information available varies substantially
depending on the payment peripherals present in the machine. For example, if
your machine does not have any card reader, there will be no mention at all of
cashless sales or revalues. The description below is based on a machine having all
potential payment peripherals installed, including two cashless devices.
Tube inventory: Current value of the coins present in each tube. (5¢ - 10¢
- 25¢ - 100¢ - 200¢)
Coin box: Current value of the coins in the box since last reset.
Bill box: Current value of the bills in the cassette since last reset.
Cash sales: Sales done using cash since last reset.
Cash sales cum.: Sales done using cash since day one (not resettable).
Cashless 1 sales: Sales done using the first card reader since last reset.
Cashless 1 cum.: Sales done using the first card reader since day one.
Cashless 2 sales: Sales done using the second card reader since last reset.
Cashless 2 cum.: Sales done using the second card reader since day one.
Total sales: Total sales, cash + card 1 + card 2 since last reset.
Total sales cum.: Total sales, cash + card 1 + card 2 since last day one.
Sales with token: Value of sales done with a token since last reset.
Sales with token cum.: Value of sales done with a token since day one.
Revalue from cash: Money added to cards using cash since last reset.
Revalue f cash cum.: Money added to cards using cash since last day one.
Revalue from card: Money added to cards using card since last reset.
Revalue f card cum.: Money added to cards using card since last day one.

Format 1 cum.: Total of litres sold from Format 1 since day one.
Format 2: Total of litres sold from Format 2 since last reset.
Format 2 cum.: Total of litres sold from Format 2 since day one.
Format 3: Total of litres sold from Format 3 since last reset.
Format 3 cum.: Total of litres sold from Format 3 since day one.
