1.2 Introduction
Thank you for selecting the Tekelek Eco Oil Heating Oil Energy Monitor. This revolutionary home energy
monitoring system allows today’s energy and environmentally conscious consumers to monitor and track
their heating oil consumption, its costs, and the heating systems environmental impact through carbon
emissions, on a daily, weekly, monthly, and annual basis.
The Tekelek Eco Oil product from Tekelek Europe Ltd consists of the Tekelek Sensor and the Tekelek Eco Oil
Monitor. The Tekelek Sensor is easily installed on your oil storage tank to measure the level of the oil. It
transmits the oil level information wirelessly to the Tekelek Eco Oil Monitor which may be located in a
convenient location inside your home.
The Tekelek Sensor uses ultrasonic technology to measure the distance from the sensor on top of the tank to
the surface of the liquid in your oil tank. As the amount of oil in your tank decreases, the distance measured
increases accordingly. The distance information or ‘ullage’ is transmitted wirelessly to the Tekelek Eco Oil
Monitor.
Litres and % fuel
Once programmed with information about your oil tank’s shape and size, the Tekelek Eco Oil Monitor
calculates and displays the amount of fuel remaining in your tank in litres or as a percentage of the tank
capacity. In addition (as oil is consumed over time) the Tekelek Eco Oil Monitor calculates and displays
usage information including the average amount of litres used per day, per week, over the last 30 days, and
over the last 365 days.

Days to Empty (DTE)
As the Tekelek Sensor continuously measures and transmits the oil level, the Tekelek Eco Oil Monitor retains
this information allowing it to ‘learn’ historical heating system usage patterns and so predict the ‘Days to
Empty’ for your home. With this information you can ensure that you order your oil at the correct time –
not too soon, and more importantly, not too late.
Costs
By entering the cost you pay for your oil during the setup process of your Tekelek Eco Oil Monitor and
subsequently when you take deliveries of oil (if the price has changed), the Tekelek Eco Oil can present your
oil usage in terms of its costs, i.e. average cost per day and per week, and the cost for the usage over the last
30 days and 365 days.
Environment
Similarly, the Tekelek Eco Oil Monitor can display your oil usage in terms of the associated production of CO2
emissions, as the equivalent quantity of KgCO2emitted per day, per week, the last 30 days and 365 days.
Installation
The Tekelek Sensor fits into the standard 32mm aperture found on most modern oil storage tanks and is
suitable for use with almost any plastic or metal tank up to 3m tall, including Bunded and Single Skin Oil
tanks. If your tank is a bunded tank, ensure that you mount the Tekelek Sensor on the inner tank.
As part of the installation the Tekelek Sensor and Monitor are ‘synchronised’ together to ensure there is no
interference from other nearby sensors.

2.5 Display Screens
There are two types of information displayed on the Tekelek Eco Oil Monitor:
CURRENT information screens – used in normal mode to show the current status of the oil level in your tank.
Change between the ‘Ltr.’, ‘%’, ‘Days to empty’, and Clock screens using the and keys.
For approximately 1 week after the Tekelek Eco Oil is installed, it collects data so that the ‘Average per day’
value may be calculated. During this period the screen will flash ‘---‘ when showing ‘Days to empty’. (In the
picture, ‘flashing’ is indicated in red).
After this period, the display may continue to show ‘---‘ (but not flashing). This indicates that a meaningful
value could not be calculated. This may occur in periods when there is no (or extremely low) usage. The ‘---‘
may be displayed in any of the HISTORICAL information screens under these conditions.
This may also happen if the Tekelek Eco Oil Monitor has been unplugged for some time. When sufficient
data has been gathered, the screen will revert to normal after a period from a few hours up to a maximum
of 1 week.
HISTORICAL information screens showing ‘Fuel usage – Litres’, ‘Fuel usage – Cost’ and ‘Fuel Usage – Carbon’.
Pressing MODE and /accesses these screens.
The Tekelek Eco Oil Monitor will automatically return to the CURRENT information screen after 30s with no
key presses within the HISTORICAL information screens. The maximum value displayed is 19999.

3.1 Full Indication
When the level in your tank reaches 12 cm from the top of the tank, i.e. from the bottom of the Tekelek
Sensor, the main display will show ‘FULL’.
3.2 Low Level Indications
When the tank level falls to within 14cm of the bottom of the tank the ‘re-fuel’ symbol will flash. When
the tank level is such that there is below 10% of the usable volume of oil left in the tank, the CURRENT
information screen alternates between showing the ‘Ltr.’ (or % or DTE) and ‘Lo’.
If the level, then drops such that there is below 5% of usable oil left:
•‘Lo’ is displayed constantly on the CURRENT information screens.
•The monitor beeps 5 times, repeating every hour, i.e. 10:00, 11:00, 12:00, 13:00, 14:00...

8. Notes
•Please retain this product manual and the installation guide. It contains practical instructions, technical
specifications and safety precaution warnings you should know about.
•The maximum displayed value for all measurements and computed values is 19999. If a measurement
exceeds this value, the display will flash. This does not affect data calculations or alarm functions.
•When used according to recommendations, the Tekelek Eco Oil monitors the oil level in your tank and
calculates and presents figures relating to the remaining oil, the historical usage, and the related
monetary and environmental costs. The Tekelek Eco Oil must not be used as verification of a ‘Weights
and Measures’ certified dispensing meter.
•Patents pending or covered by one of the following patents: S2003/0882, EP2131164 (A1),
US2006261966 (A1), US7277020 (B2), IE20030882 (A2), S2008/0466, US2009/0303059 A1
•For correct usage calculation, a minimum of 7 days between tank fills is required.
•The Tekelek Eco Oil Monitor is intended to be connected to a power source continuously. It contains a
small battery to keep time during power cuts. If the Tekelek Eco Oil Monitor is left unpowered for an
extended period, then the battery will deplete, and information may be lost. When you are not using
your domestic oil heating system, you may unplug the Tekelek Eco Oil and store it until you wish to use
your heating again. Its back-up battery and internal clock keep track of the days as they pass.
•When you next use it, on starting to use your heating again, the Tekelek Eco Oil will continue
monitoring your oil usage, and calculating the financial cost and environmental impact.
•When the Tekelek Eco Oil has been unplugged and is plugged in again, it will start up in ‘Lrn’ mode.
Simply press any key to exit.
•When you are receiving an oil fill, the Tekelek Sensor cannot receive a reliable echo due to turbulence
within the tank and may cause the Tekelek Eco Oil Monitor to temporarily display some error
messages. Should the tank be filled above the recommended 95% this will obstruct the sensor signal
until the oil level drops below 120mm from the sensor. The sensor will be unable to send accurate
readings during this period.
•The Tekelek Eco Oil owner should note that the first fill amount of oil into a tank will differ from the
amount shown on the display. This is due to the fact that the Tekelek Eco Oil Monitor displays the
volume of Usable oil available. The Tekelek Eco Oil Monitor in its calculations makes an allowance of
8cm of unusable oil in the bottom of the tank due to the location of the bottom outlet or the top
discharge pipe.
•Not suitable for pressurised containers. Only use on tanks vented to the atmosphere.
•Only access the Reset Switch if instructed by customer service.
•Changes in temperature can result in contraction and expansion of the tank and hence can affect the
tank capacity. Such changes may affect your readings.
•You only need to complete this step if there was a gap of more than an hour between completing STEP
2 and STEP 3.
•To reset the usage calculations, press SETUP for 3 seconds to enter SETUP mode and then press ENTER
repeatedly until SETUP 10 is shown.
The segments at the bottom of the display will be flashing. Press the ENTER key for 5 seconds. The
screen will temporarily show ‘CALC’ and then returns to showing SETUP 1 -Setting the Time (hrs).
Press SETUP to leave SETUP mode.
