AT-WFM
Water Flow Monitor
A. GENERAL INFORMATION
The AquiTron AT-WFM water monitoring system that has been specically designed to help achieve the requirements of BREEAM 2018
(BRE Environmental Assessment Method). The AT- WFM system will allow designers, M&E contractors and developers to achieve the one
of the two WAT 03 Credits available to reduce the impact of water leaks that may otherwise go undetected. (To obtain the second available
WAT 03 credit Please see our product AT-OFC). The AT-WFM system is designed to monitor water owing through a pulse water meter. If
the volume of water exceeds the pre-set limit (customer adjustable) the system will alert the customer and, if an optional valve is tted,
can isolate the mains water, therefore limiting the amount of water lost to a leak and subsequent damage.

C. FITTING THE MODULE
The unit should be installed in a dry area with easy access. This controller is not suitable for external use.
Before installation the front section should be removed and stored somewhere safe. NOTE : To open the enclosure
Remove the two screws at the bottom of the enclosure see Fig B. on page 3.
To remove carefully unplug the interface board as shown in g A. Before doing so make sure that the AT-WFM is switched
o and the battery is disconnected.
Using the pre-drilled holes use suitable xings to secure the base unit to a at surface. If the base is distorted the front
cover may not t correctly.
It is recommended mains power is provided from an adjacent un-switched fused spur. This must be fused correctly. Fuse
rating should be 3 amps.
It is recommended not to apply power until all connections are complete.
Once all connections are in place the front panel should be plugged in and the front panel attached.
Note: Do not allow the front panel to hang from the ribbon cable. Take care not to trap or damage the ribbon cable when
installing the front panel.

AT-WM should be installed by a competent installer, in-line with current IEE regulations, using sound engineering practice
and in recommendations laid down by the HVCA.
D. WIRING
The diagrams will serve as a visual aid, but it is recommended that a competent plumber carries out the assembly and
installation of any included water meters and solenoid valves in line with the manufacturer’s instructions. Direction of ow
is essential for correct operation. Connect the pipe to the water meter / valve according to markings on the valve body.
Apply pipe compound sparingly to male threads only. Ensure compound does not enter valve or meter. Avoid undue strain
on pipework by proper support and alignment. Type PN16 mating anges will be required on some models over 50mm.
Never hold the water meter or solenoid body when tightening.
E. PLUMBING INSTALLATION
Figure A - Interface board
Connector : Plugged In Connector : Disconnected
We recommend that meters and valves attached to the AT-WFM are installed with a maintenance by-pass and strainers to
prevent debris entering them. They can be tted vertically or horizontally. Note the direction of the ow arrows marked on
the water meter and valve to ensure they are tted correctly. Do not overtighten plastic ttings. Observe rules on distance
from pipe elbows to meters to ensure correct ow through the water meter.
F. HELPFUL HINTS
Clean periodically depending on conditions. Keep the medium owing through the water meter / valve free from dirt. While
in service, the Solenoid Valve should be operated at least once a month to ensure proper cleaning and closing. We strongly
recommend a strainer is tted prior to any meters or valves to prevent debris fouling the mechanism.

If the unit is to be used as single channel unit (only one water meter) use indicated channel 1 connections. Using wiring
instructions above, connect each accessory to the controller. See relevant section for further connection details.
The Input connection can be made to an intruder alarm for automatic switching between high and low volume periods
when the alarm is activated. This should be a volt free contact.

H2. VOLT FREE RELAY CONNECTIONS
Figure 5 - Volt Free Relay
Connections
Note: This output is volt free, no power is provided from these
terminals.
The AT-WFM is equipped with a single SPDT volt free relay for
control of accessories. This relay output operates when the unit
goes into alarm. It can switch a maximum resistive load of 3amps @
230Vac/24Vdc.
The relay allows for control of equipment requiring a normally open
or closed volt free contact, such as BMS. Or can be used to control
remote accessories such as AT-SD3 speech diallers or AT-BCN-A
beacons, third party valves etc.
H3. EXTERNAL TRIGGER INPUT
Figure 6 - External Volt Free
Connection
This input allows the controller to be put in and out of high and low
volume settings by external equipment such as a key switch or alarm
system. i.e intruder alarm for entry / exit setting.
A volt free normally open input is required. If enabled in software
closing this contact will place the AT-WFM unit into low volume
mode. See section L3. for set up information.

H4. WATER METER CONNECTION
Connect the pulse output of the water meter to the AT-WFM as shown above. The connections are not polarity sensitive. If the cable on the
meter requires extending the connection should be made using a shielded 2 core cable.
Minimum cable size should be 1.0mm² for runs of up to 100m, for runs above this we recommend a minimum cable size of 1.5mm². For
cable runs above 50m or runs adjacent to mains cabling the shield of the pulse cable should be grounded at the controller end only using
one of the indicated ground terminals to prevent interference.

L2. PROTECTION LEVEL MODE
Menu>>Setup>>Password>>Protection Level Mode
Protection Level mode is the measurement used to monitor the ow through the pulse meters. There are three modes available:
• Volume per
• Timed
• Crosscheck
The other settings available on this screen will change according to the mode selected.
L2.A VOLUME PER
Figure 19 - Protection Level - VOLUME MODE
Default setting is ‘Volume Per’. In this mode the
system will allow a set amount (volume) of water
through the pulse meter during a dened period. e.g.
1500ltr water volume allowed in any half hour period.
In this setting there are three further options for
dening that period:
• ½ Hour
• Hour
• Day
By combining these values you increase or decrease
the ‘sensitivity’ of the systems measurement of ow
volume.
To edit the ow volume, press the edit button under the high or low volume value you wish to adjust to enter the value edit screen. Then
use the arrows to select and adjust values, then press enter to save and return to the screen above. (See section L3. on adjusting high low
volume times).
In the example shown in Fig.19 above the system will allow 1500ltr per half hour during high volume periods, and 60ltr per half hour
during low volume periods. Any water use above this level will put the system into alarm.
L2.B TIMED
Timed does not measure volume. Instead it will
allow water ow for dened periods of time. Periods
available are:
• 10 minutes
• 15 minutes
• 30 minutes
• 60 minutes
Any uninterrupted ow above this user dened time
will put the AT-WFM into alarm. In the example in g.20
the unit is set for 10 minutes. If the water ows for 11
minutes the system will go into alarm. If the water runs
for 9 minutes, stops, then ows for another 9 minutes,
stops, etc the system will not go into alarm.
Figure 20 - Protection Level - TIMED MODE
There are two reset options available:
Manual Reset – The Reset button must be pressed to stop the alarm and reset the controller
Automatic Reset – The controller will automatically reset as soon as the water ow stops
Note: A ow switch can be used in place of pulse water meters on this setting if required.

L2.C CROSSCHECK
Figure 21 - Protection Level - CROSSCHECK MODE
Crosscheck gives the AT-WFM exibility to be used
in applications where a comparison of two meters is
required, e.g. a block of ats with heat interface units,
especially useful if ats are left unoccupied for long
periods. The ow and return into each at can be
monitored. If more water goes in than comes out then
the water loss will be noted by the AT-WFM and an
alarm generated.
There are two adjustment in this section that aect the
sensitivity of alarm conditions, tolerance and volume
per.
Tolerance is measured in percentage and allows a dierential of up to 20% between channel pulse inputs. Options are:
• 0%
• 10%
• 20%
Volume per species the period of measurement. Options are:
• ½ hour
• Hour
• Day
e.g.1. Select tolerance 10% and volume per ½ hour. This means each half hour if the pulse input of each channel varies by more than
10% the system will go into alarm. On this setting an expected 100ltr measurement could vary by up to 20ltrs per half hour before an
alarm would be given. Total of 480ltrs per 24 hour period.
e.g.2. Select tolerance 20% and volume per Day. This allows up to 20% dierence in channel pulse inputs in any 24 hour period. On this
setting an expected 100ltr measurement would only allow 40ltrs dierence over a 24hr period.
Important Note: Selecting 0% tolerance requires the pulse inputs to be matched at all times.
Important Note: For eective operation identical pulse Meters with high accuracy must be used. Contact Aquilar for details on our
range of suitable water meters.

Time select options are:
• Daily – Times are the same for all days
• Weekly – Dierent times can be set for each
day (each day must be set individually)
• Week/End – Times are set for week days and
weekends separately
• Ext Input – High and low volume times are
triggered via an external input such as a key
switch or alarm system i.e intruder alarm for
entry / exit setting. Trigger inputs must be a
normally open volt free contact (See section
H.2, closing to trigger into low volume. (See
section H.3 for connection information)
In this screen you set the start and end times required for high volume level. Any time outside of the parameters input here are
considered low volume level by the controller, and will be measured as such according to the volume levels in put in section H2. Volume
per.
The general rule for the high volume times is to set this higher value for when the building is occupied. Eg. For an oce you may want
to set the high volume (building is occupied) period to start at 8.00 and end at 18.00. In this example in the time between 6pm and
8am the controller will be using the low volume (building is unoccupied) setting.
In all options press the edit button under the value you wish to adjust to enter the edit screen, then use the arrows to select and enter
the value, press enter to save.
