APOLLO SMART PRODUCT MANUAL
1) INTRODUCTION
Thank you for selecting the Apollo Smart 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 Apollo Smart product from Dunraven Systems consists of the Apollo Smart
Transmitter and the Apollo Smart Monitor. The Apollo Smart Transmitter is easily
installed on your oil storage tank to measure the level of the oil. It transmits the oil level
information wirelessly to the Apollo Smart Monitor which may be located in a convenient
location inside your home.
The Apollo Smart Transmitter uses ultrasonic technology to measure the distance from the
Transmitter 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 Apollo Smart Monitor.
Litres and % fuel
Once programmed with information about your oil tank’s shape and size, the Apollo Smart
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 Apollo Smart
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 Apollo Smart Transmitter continuously measures and transmits the oil level, the Apollo
Smart 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 Apollo Smart
Monitor and subsequently when you take deliveries of oil (if the price has changed), the
Apollo Smart 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 Apollo Smart Monitor can display your oil usage in terms of the associated
production of CO2emissions, as the equivalent quantity of KgCO2emitted per day, per week,
the last 30 days and 365 days.
The Apollo Smart Transmitter 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 Apollo Smart Transmitter on the inner tank.
As part of the installation the Apollo Smart Transmitter and Monitor are ‘synchronised’
together to ensure there is no interference from other nearby transmitters.

The Apollo Smart Monitor is intended to be connected to a
power source continuously. It contains a small battery to keep
time during power cuts. If the Apollo Smart 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 Apollo Smart
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
Apollo Smart will continue monitoring your oil usage, and
calculating the financial cost and environmental impact.
When the Apollo Smart 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 Apollo Smart Transmitter
cannot receive a reliable echo due to turbulence within the tank
and may cause the Apollo Smart Monitor to temporarily display
some error messages. Should the tank be filled above the
recommended 95% this will obstruct the transmitter signal until
the oil level drops below 120mm from the transmitter. The
transmitter will be unable to send accurate readings during this
period.
The Apollo Smart 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 Apollo Smart Monitor displays the
volume of Usable oil available. The Apollo Smart 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.
Pressing the reset will erase all historical data.
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.

4) DISPLAY SCREENS
There are two types of information displayed on the Apollo Smart 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 rand skeys.
For approximately 1 week after the Apollo Smart 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 by the red circle).
After the 1 week period has passed, 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.
The screen may also show ‘---‘if the Apollo Smart Monitor had been unplugged for some time. In this
case ‘---‘ means that it has no recent reading from the transmitter with which to display a value on the

5. APOLLO SMART - TANK SETUP
To calculate the volume in your tank the Apollo Smart Monitor
needs to know the shape of your tank. There are three basic
shapes as illustrated. Identify the shape that is closest to the
shape of your tank. Each Apollo Smart Monitor is supplied with
the default settings as shown. The Apollo Smart Monitor must
then be configured to your own tank’s dimensions (see
installation guide). Minimum and maximum allowable values for
tank dimensions are shown in this table.
6. APOLLO SMART LEVEL ALARMS/INDICATIONS
When the level in your tank is below 12 cm from the top of the tank, i.e. bottom
of the Apollo Smart Transmitter, the main display will show ‘FULL’. This will
occur when there are 10 bars showing on the bar-graph.
When the tank level falls to within 14cm of the bottom of the tank the ‘bowser’
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 buzzer sounds 5 times an hour at the top of the hour, i.e. 10:00, 11:00, 12:00, 13:00,
14:00...
The RED light flashes. This continues until there is an oil delivery and the level rises.
