Tanktronic is an electronic tank
management system which provides an
easy-to-use solution for monitoring water
conditions within a tank and controls
filling all in one system.
Pressure and temperature readings from
a continuously submersed sensor are
taken and shown on a user friendly
interface informing the customer of the
water level and status.
Tanktronic can be used as an independent
monitoring system or installed with
several different modules to build a
sophisticated tank control system.
Tanktronic's features include electronic
fill, remote control and water usage
monitoring.
Glossary (see diagram on page 20)
Close Level: The Close Level is the
maximum desired water level inside the
tank. The valve(s) will close when this
level is reached. The Close Level can
be set either manually or automatically.
Fill Delay: The Fill Delay is the depth
of water lost before the system opens
the valve to begin filling; it is the depth
of water displaced in relation to the
Close Level.
High Level Alarm (Alarm Level H):
This alarm will trigger when the High
(maximum) Level is reached and the
valve has not shut off. It must be set
higher that the Close Level.
Low Level Alarm (Alarm Level L):
This will trigger when the Low (minimum)
Level is reached and the valve has not
opened to allow water to flow. This level
must be lower than the set Low Level.

Typical System Layout
Before installing your Tanktronic system,
it is suggested that you assess the tank
environment to establish the best
position for the equipment. You should
also assess the most appropriate
locations for any permanent fixings or
adaptations to the area. This assessment
also ensures that you have adequate
cable and fixings to complete the
installation before starting.

2. MOUNTING THE
MAIN CONTROL UNIT
The main control unit should be mounted
to a solid surface, such as a wall, within
easy reach of the tanks being monitored.
1. Open the main control unit and offer
the unit to the wall.
2. Ensure the main control unit can be
opened fully, with no obstructions
below the unit that could limit access.
3. A drilling template is included in the
packaging and this can be used to
mark the drilling points. Use the
complete template to mark the
position of the main control unit.
4. Mark the position of the mounting
holes as per the drilling template. Pay
particular attention to ensure that the
cable glands are free from obstruction.
NOTE: Remove the unit prior to drilling.
5. Drill 8mm diameter holes and insert
rawlplugs.
6. Screw unit in position using floating
washers and #6 screws provided.
Take care not to trap the ribbon cable
when closing the unit.
It is also possible to mount the main
control unit on a DIN Rail.
3. MOUNTING SUBSIDIARY AND
BATTERY BACK-UP MODULES
If the installation involves multiple tanks
or a battery back-up case is required,
please follow the instructions below.
1. Slide tabs with a screwdriver as
shown below.
NOTE: These tabs are not load-
bearing and any extra units should
be supported during fitting.
2. Align the subsidiary module to the
main control unit using the tabs.

4. MOUNTING VENT BOX 5. INSTALLING THE
SENSOR IN THE TANK
Allocate one sensor to each tank. It is
advisable to label each sensor (Sensor 1
for example) and its corresponding tank
(Tank 1 for example) prior to lowering the
sensor into the tank.
A 25mm hole should be drilled in the top
of the tank, preferably away from the
water in-let pipe. Lower the sensor into
the tank so it touches the bottom of the
tank. Take care not to allow debris to
enter the tank. It is suggested that the
tank is drained down and chlorinated
before refilling. A tapered rubber bung is
fitted to the sensor cable to hold the
sensor in place in the tank; slide this
bung down the cable and force into the
hole through which the sensor has been
lowered, securing the cable in place.
The vent box is supplied with self-adhesive
pads to fix it to the top of the tank being
used. Four screws are supplied to allow
you to permanently fix the box.
Four clearance holes are located in the
corners of the box to facilitate such fixing.
Notes on Positioning
To reduce the effects of turbulence, do
not position the sensor close to the inlet.
Take cable length into consideration to
ensure there is sufficient cable length to
reach the vent box.
NOTE: Do not cut the sensor cable and
take care not the damage the clear
plastic tube at the centre of the cable.
To Tanktronic
To sensor/s

Installation
Connect the control valve inlet to the pipe
work using either screw thread fittings or a
flange and appropriate gaskets and bolts.
Note the arrow on the side of the valve
indicating the direction of flow.
Connect the control valve outlet to the
tank. An optional discharge flange
assembly is available.
Commissioning and Testing
Complete the tank set-up setting the
appropriate level settings.
Connect the pilot valve flying leads to the
cable back to Tanktronic. Gently open the
upstream servicing valve.
Operate the system – complete an auto
set-up or temporarily lift the sensor cable
to initiate filling. Lowering the sensor to the
bottom of the tank will close the valve.
The closing speed valve can be adjusted to
avoid excessive pressures (water hammer)
developing in the supply pipe as the
control valve closes. The closing speed
valve is the slotted screw with lock nut
found on the top cover of the control valve.
The closing speed valve should be set to
provide a slow closure of the control valve.
If the closing speed is too short, a bang
will be heard. This must be avoided to
prevent damage to the pipe and system.
Turning the closing speed valve clockwise
will increase the delay. If the control valve
fails to close or does not close quickly
enough, the closing speed valve should be
turned anti-clockwise to shorten the
closure time.
Servicing and Maintenance
No routine maintenance should be
necessary. If debris has entered the water
supply, isolate the supply to the control
valve assembly and inspect/clean as
appropriate.

10 INSTALLATION 11INSTALLATION
6. INSTALLING THE VALVE ASSEMBLY
For 2” fittings and greater, use a
control valve with flange fittings
The valve assembly consists of a pilot
and control valve. Installation of valves
should be in accordance with The Water
Supply (Water Fittings) Regulations 1999
and BS6700:1997 Para. 2.2.4
Operation
When the water in the tank drops below
the desired Open Level, Tanktronic will
send a signal to the pilot valve to open.
This relieves the pressure on the top
surface of the diaphragm, causing the
control valve to open. When the water
level has reached the desired Close Level,
Tanktronic sends a closing pulse to the
pilot valve, causing water pressure to build
on the diaphragm surface and close slowly.
The control valve can be mounted
horizontally outside the tank either at floor
level or above the tank water level. It can
also be positioned vertically in the rising
main (up to and including 150mm (6”) only).
A servicing valve must be fitted upstream of
the control valve. A servicing valve fitted
downstream of the valve is also recommended
to completely isolate the valve for maintenance.
It is recommended that a coarse particle
strainer (not supplied) is installed upstream
of the control valve to prevent debris entering
it unless the valve is mounted vertically.
Discharge into the tank – if an air gap is
required for back flow protection, the
discharge must be above the water level.
Prior to installation, all pipe work should be
flushed through to remove all debris.
Decide upon the best location for mounting
the valve assembly. Refer to the consulting
engineer’s plans as appropriate.
For 1½” or smaller piping,
use a screw-thread filling valve

12 INSTALLATION 13INSTALLATION
Twin Tank Installation
To ensure a continuous supply of potable
water, some installations feature one
large tank with a central partition or two
smaller tanks connected in parallel.
Both compartments are normally used
with an interconnecting balance pipe
and a central draw-off connection.
To minimise the risk of water-borne
diseases, it is desirable to ensure regular
circulation through both tanks. For parallel
installations this is achieved by filling both
compartments/tanks simultaneously.
When connected correctly both tanks will
receive an equal flow – irrespective of
which pilot valve is open.
Normal Installation
To avoid overfilling one tank, a large
balance pipe must be fitted with a central
take-off (i.e. the distance from the tank
outlet to the draw-off pipe must be of
equal diameter and length).
Likewise the filling pipes to each tank
should be of identical head loss (i.e. same
diameter, length and fittings). It is
advisable to leave a substantial distance
(e.g. 150 mm) between the Close Level
and the Overflow Level of the warning
pipe (see diagram opposite). This will
allow for some imbalance in water levels
between the tanks.
It is suggested that the servicing valves to
both KB pilot valves be open. The control
valve will open fully and fill both tanks
when either or both KB pilot valve is
open. The Open Levels and Close Levels
would normally be set the same for each
tank. The pilot lines need not be
symmetrical.
Maintenance
One tank/compartment may be isolated
for cleaning, chlorinating or for any other
reason. To isolate one tank, close all the
valves relating to this tank (i.e. KB pilot
servicing valve, filling isolating valve and
the outlet isolating valve). The flow rate
into the functioning tank will increase. If
this flow is excessive, throttle the flow
with the main servicing valve or the filling
isolating valve.

7. WIRING CONNECTIONS
Power
Tanktronic requires a normal 240v mains
power supply from a switched fused 3A
supply.
1. To connect the power cable, first slide
the cable through the safety sleeve,
then attach it to the connector.
2. Slide the safety sleeve back over the
connector before pushing the assembly
firmly into the required socket. This
should be duplicated for any
connection to the Volt Free Contact
Out (VFCO). This is a safety feature to
reduce the chance of an electrical
short circuit should a wire come loose.
3. Ensure cables are fed through the
cable glands as displayed and cables
are free to access the tanks, valves
and any alarm unit being used.
4. Replace main control unit cover.
NOTE: Do not connect the valve to the
main control unit for initial set-up
otherwise the valve may open and
flooding may occur.

7. TANK AREA SET-UP
Setting the Tank Area will allow Tanktronic
to calculate the volume of stored water
when the sensor is submerged. The volume
is displayed on the HOME screen in litres.
The Area will need to be entered for each tank.
To calculate your tank area:
For a square or rectangular tank
multiple the length by the width,
both measured in metres.
For a circular tank multiply half the
diameter, measured in metres, by
itself and then multiple that by 3.142.
E.g. If the tank is 6m across, half the
diameter is 3m, multiplied by itself, 3m, is
9m. Then multiply this by 3.142 giving an
area of 28.28m2.
To set up the Tank Area, select from the
MAIN MENU screen:
Press or to enter the menu.
The default setting is 10m2. Use or
to set the desired value.
Save and return to Config menu.

FAQs
I have a twin tank arrangement
and want to drain them; what
special procedures do I have to
take with Tanktronic?
This applies if you have two tanks
serviced by one valve or two tanks
serviced by two.
If you need to drain a tank for maintenance,
etc. you will need to carry out the following
procedure.
Manually isolate the tank via the balance
and inlet valves.
Lock the appropriate sensor using
Tanktronic. Select from the MAIN
MENU screen:
Select ‘Lock’ and press on the
subsequent screen to save the setting.
This will prevent nuisance alarms, but
does not prevent the second tank from
filling, maintaining water supply.
Proceed with maintenance of the tank.
On completion of maintenance, manually
open the isolation valves; water will flow
between the tanks via the balance pipe
and start to backfill Tank 1.
Allow ‘Balancing’ to ensure close delay is
reached in Tank 2. You can now ‘Unlock’
the Tanktronic sensor. Select from the
MAIN MENU screen:
Select ‘Auto’ and press on the
subsequent screen to save the setting.
Tanktronic will now issue a Low Level
Alarm, until the minimum level is reached
or until the alarm is cleared.
To conduct maintenance for the second
tank, follow the same procedure but
‘Lock’ Tank 2.

How do I know if the mains
power is off?
If mains power is lost to the main control
unit, and the battery back-up comes
into use, the status LED will flash green,
until mains power is re-established.
A message also appears on the
display, stating ‘Warning: Mains Off’.
If there is no battery back-up, the LED will
not light up and the display will be blank.
How many sensors and tanks
can I monitor/fill with
Tanktronic?
With one main control box you can
monitor/fill two sensors placed in two
separate tanks (see page 4, Section 1.
Assessing System Layout). Two additional
sensors/tanks can be monitored/filled with
the addition of each main control unit. For
example, to use Tanktronic with four tanks,
you would need two main control units.
How many battery back-up
boxes do I need?
The battery back-up module is available
and only used in the event of mains
power being severed from the main
control box. Only one battery back-up
module is required to support any
number of main control units, but the time
such back-up lasts reduces with more
control units attached to it.
Do I need a battery back-up box?
No, the system will run from the mains
supply without need for the battery
back-up.
Do the various units need to be
level? Is this important?
The units will operate if not perfectly level,
but we suggest all effort is made to mount
the unit to a common level, especially if
multiple boxes (main control box and
battery back-ups) are being mounted
together, avoid any stresses being put
upon the supporting tabs and cabling.

Sensor Set-up
NOTE: This step is only necessary if
you have purchased a new sensor.
If only one tank is to be monitored, refer to
Single Tank. If more than one tank is to be
monitored, refer to Twin/Partitioned Tanks.
Single Tank
The Close Level is the maximum desired
water level inside the tank. The valve(s) will
close when this level is reached.
The system must be configured so it
recognizes the sensor. The sensor must be
given a name, referred to as a ‘Sensor
Address’ on the system.

Sensor Calibration
NOTE: This step is only necessary if
you have purchased a new sensor.
Prior to commencing calibration, ensure
the sensor is out of water.
Calibrating the sensors will ensure
accurate level readings are obtained whilst
the sensor is in use. Failure to do this may
result in false readings or nuisance alarms.
Ensure the sensor is out of the water
before calibration commences.
From the MAIN MENU screen select:
The following message will appear.
‘Are you sure?’ Yes or No. Select ‘Yes’
Then select:
The following message will appear:
‘Sensor calibration must be out of
the water’.
Select or and calibration will begin.
When complete, the following message
will appear ‘Sensor Calibration
Complete’; select .This will take about
a second.
The water level will read as 0.00m when
the sensor is out of the water.
Exit to HOME screen (Repeated
presses) and check level information on
the HOME screen.
This information is also shown in the
Tank 1 status screen.
The sensor can now be lowered into
the tank. As the sensor is lowered, the
HOME screen level reading will up-date.
NOTE: There is a slight delay to allow
the sensor to settle at a particular depth
before that level is displayed on the
screen. This is to prevent nuisance
readings caused by turbulent water.
