Fitting Instructions

1. Overview

Eco-eye consists of a sensor, transmitter and receiver/display unit. The sensor clips around the incoming supply cable, usually at the meter, and monitors the total current passing through it. This is done by the user without disturbing or cutting any wiring and without the need for a qualified electrician. The sensor plugs into the transmitter unit and the information is sent wirelessly to the receiver unit which translates it into meaningful information - Kilowatts, Cost or CO2 emissions.

Live electricity cable tester (shown right) Supplied to ensure that the sensor is clipped around the correct electricity cable. The LED should light up if you have located the live electricity cable.

Remove the tester once you have located the correct cable and plug the sensor cable into the transmitter.
Note - No harm will be done to Eco-eye or to the electricity supply if the sensor is inadvertently fitted around an incorrect cable.

2. The Sensor

The standard sensor unit is of a two part construction and clips around any live cable up to 13mm in diameter. Typically this will be found on the far right of the meter and coloured or marked with red or brown. If the meter is situated remotely or in an external box, the sensor can either be fitted onto the cable at the meter or inside the property where it enters the fuse board. The latter is preferable in order to minimise signal loss.

NOTE 1: The sensor unit will buzz especially when not connected to the transmitter. This is perfectly normal. Ensure only a single live cable passes through the sensor.

NOTE 2: Eco-eye will only work with individual cables (i.e. not multi-core cables) and is therefore not intended for the monitoring of individual appliances.

NOTE 3: It is NOT necessary for the sensor to be a close fit around the cable. However, alternative sized sensors are available for special applications – details available on request.

Standard Size
  • Suitable for cables up to 13mm in diameter.
  • Press the sides to separate the two parts. Click shut when round cable.
Larger Size
  • Suitable for cables up to 16mm in diameter.
  • This unit is hinged - Pull the catch to open. Click shut when round cable.
3. The Transmitter Unit

Press the release lever to remove the wall plate from the transmitter and using the two self-adhesive pads (supplied) or screws (not supplied) affix in a convenient position close to the cable being monitored. Ensure the release catch is positioned to the left side.

Fit 2 x AA batteries into the transmitter ensuring the correct orientation and polarity (see illustration below). The LED should initially flash twice (brightly) and then emit a regular 4 second low intensity flash.

NOTE: The red LED light flashing every 4 seconds indicates that the wireless signal is transmitting correctly. A solid light indicates an irregularity has been detected. In this situation, remove the batteries and recommence the start up procedure.

The transmitter can accept up to three sensors and is suitable for monitoring single , multi-phase or split-source supplies. (additional sensors required).

ONLY NOW SHOULD YOU FIT BATTERIES TO THE RECEIVER UNIT

4. Receiver/Display Unit - Elite or Mini

Remove the battery cover and insert 2 x AA batteries, ensuring correct polarity (see illustration below). Replace the battery cover. The unit goes through a power-up routine whereby it is possible to change certain parameters (currency symbol, voltage etc. see Section 10). If the sensor and transmitter units are connected correctly, the Eco-eye receiver will automatically display the current KW reading. A handshake icon will also become visible at the bottom left hand side of the screen and ‘blink’ every time an incoming signal is received.

NOTE: All Eco-eye units can be powered with the optional AC/CD mains adaptors. The socket for the transmitter is located adjacent to the Sensor socket. The socket for the Mini display is on the side of the unit and the socket for the Elite is located under the Battery Cover.
5. Elite Mounting Options

Free-standing option: Release catches at B (see Fig. 1) and gently pull out the hinged stand until it clicks into the open position.
Eco-eye can then be used on a table, desk or other flat surface (as in Fig. 2).

Wall-mounted option: Release catches at A and B (see Fig. 1) and gently remove the mounting frame. Fit the mounting frame to the wall in the required position using the adhesive pads (supplied) or screws. Present Eco-eye squarely to the mounting frame until catches A and B are lined up and can latch into position (see Fig. 3).

Alternative wall-mounting option: Once fitted as above, Eco-eye can also be pivoted forward (see Fig.4) until a ‘click’ is felt. This option is ideal for mounting your unit at a higher level on the wall. NOTE: Eco-eye must be returned to the standard wall mounting position before it can be removed from the mounting frame.

6. Programming Cost and Time

Eco-eye needs to know the time and the unit cost of your electricity in order to provide you with the correct information.

(a) Press and hold the OVAL BUTTON for 3 seconds minimum. On release the default currency symbol (£, $ or €), ‘KW’ icon and ‘SET MODE’ icons will be displayed together with flashing numerals which can be adjusted to your own electricity tariff using the + and - ARROW KEYS.

NOTE: The display is to 3 decimal places for greater accuracy i.e. 10.5 pence per unit is displayed as £0.105.

Remember: 1 kW = 1000 watts,

1000 watts for 1 hour duration = one kWh

1 kWh = 1 unit of electrical energy

(b) Press the OVAL BUTTON again to enter the current time. The ‘TIME’ icon becomes visible and minute numerals will flash. Use the + and – ARROW KEYS to set the minutes.

(c) Press the OVAL BUTTON again to activate the HOUR numerals. Use + and – ARROW KEYS to set the hours in 24 hour format.

(d) Press the OVAL BUTTON to return to normal display mode and save changes.

NOTE: 10 seconds of inactivity in set mode will return the unit to normal display mode, without saving changes.

7. Operation

The operation of the Eco-eye receiver/display unit for real-time USAGE is controlled solely by the OVAL BUTTON A.

From the initial KW usage screen:

(a) Press the OVAL BUTTON once to show the ‘COST PER HOUR’ mode.

(b) Press the OVAL BUTTON again to show the ‘COST PER DAY’ mode.

(c) Press the OVAL BUTTON again to show the ‘COST PER WEEK’ mode.

(d) Press the OVAL BUTTON again to show the ‘COST PER MONTH’ mode.

(e) Press the OVAL BUTTON again to show the ‘COST PER YEAR’ mode.

(f) Press the OVAL BUTTON again to show the ‘KG CO2’ mode. This displays the amount of CO2 which will be discharged into the atmosphere per month based on your CURRENT usage.

(g) Press the OVAL BUTTON again to show the current time.

(h) Press the OVAL BUTTON once more to return to KW consumption mode.

8. Historical Data

Whilst you are in the real-time modes (listed in 7. Operation) you are able to recall historical data related to that mode. For example, if you are displaying COST PER DAY, you can look at the individual costs for the last 32 days. The ‘HISTORY’ icon flashes when historical data is on the display.

(a) Pressing the - ARROW KEY once will take you to the ACCUMULATED history mode and will display the actual amount/cost already
consumed in the current period. e.g – Current hour or day, etc.

(b) Pressing the - ARROW KEY again will display '-01' whilst the key is depressed and upon release the value displayed will be the actual amount/cost of usage in the '-01' selected time period. Pressing the key again will display '-02' etc.

(c) Pressing the Oval Button A at any time returns the unit to real-time operation.

NOTE: The memory in YEAR MODE has an ability to be reset at any point by simply pressing and holding the OVAL BUTTON for 15 seconds at which point ‘- - - . - ’ will be displayed. This data can be viewed at any point by following the instructions at (a) above. This feature is particularly useful if you wish to measure your consumption during a specific period of time.

9. Sequential Mode

Eco-eye can automatically cycle through the real-time modes coincidentally with the 4 seconds transmission update enabling you to view all modes in 7 (a) to (h) consecutively. To initiate this mode, use the following sequence in quick succession:

(a) Press and hold the OVAL BUTTON,

(b) Press and hold the + ARROW BUTTON,

(c) Release the OVAL BUTTON,

(d) Release the + ARROW BUTTON.

(e) To cancel the sequential mode, simply repeat this operation.

10. Changing currency and voltage symbols

REMINDER: When Eco-eye is initially activated, it goes through the ‘power-up’ routine, whereby several screens of information are displayed in succession. Whilst the following screens are visible it is possible to change the default icons/values.

(a) Currency: When a currency symbol (£, $ and Euro) becomes visible, press either + or - ARROW KEY to toggle through the available options. Once the desired currency symbol is displayed, allow the unit to continue the ‘power-up’ routine and that setting will be stored as the new default.

(b). Voltage: When the VOLTAGE icon is visible, press either + or - ARROW KEY to change the numeric display. Once the desired value is displayed, allow the unit to continue the ‘power-up’ routine and that setting will be stored as the new default.

11. To change send/transmit frequency

If a number of Eco-eyes are situated in close proximity it may be necessary to change the transmission frequency. The default channel is 2 but any other number from 1 to 30 can be selected, provided both the transmitter and receiver are set to the same number.

(a) Transmitter Unit: Remove the batteries. Press the small recessed button adjacent to the battery compartment using a small probe, whilst at the same time re-installing the batteries. The LED on the front will illuminate. Release the button, then immediately press it the same number of times as the desired channel number e.g. Press 5 times for Channel 5. The LED on the front will then flash (brightly) the same number of times as the channel selected before emitting the normal low intensity flash coincidental with the selected update rate. The default channel is now redefined.
Use pencil or similar to depress
(b) Receiver Unit: During the ‘power-up’ routine, the receiver will display ‘CH02’ (default channel being 02). Use the + and - ARROW KEYS to change the channel number to the same number you have selected for the transmitter unit (1 - 30). Allow Eco-eye to continue the ‘power-up’ routine and the revised selection is stored.
12. Troubleshooting

Low Battery A double flash on the transmitter indicates that the batteries will soon need replacing. The VOLTAGE icon is also shown on the display screen to denote this.

Signal Strength: The handshake icon (bottom left of screen) has the following functions:

Long on, short off = good signal
Long off, short on = weak signal
No icon visible = no signal from transmitter

Improving the Range of your Eco-eye: In rare situations the range may be weaker than it should be and may result in no or rogue readings on the display unit . This problem can be overcome by using the supplied antenna (as shown below) and simply fixing it to the back of the Eco-eye display unit in the recess provided .

Antenna Back of Elite Display Back of Mini Display
Channel Identification: As soon as batteries are put into the transmitter, the LED flashes to indicate the channel E.G: for Channel 2 (the normal default), it will flash twice. Channel selection is one of the set-up screens on the display, so can be seen by removing and replacing the batteries. It is displayed as, for example, ch02. See section 11 for information of changing channels.
