Page 4: Introduction
Introduction Introduction Thank you for choosing eddi . Of course, we think you have made an excellent choice and are sure you will be very happy with the features, benefits and quality of this myenergi product. eddi is an automatic power controller for heaters. It 'tracks' available surplus power from a grid-tied PV or Wind turbine system and varies the power to the heater to match the surplus power, therefore ensuring all of the green energy is fully utilised. -

Page 12: Boost Timer
Operation Boost Timer eddi can be programmed to 'boost' the heating for each heater at certain times. Boost, means that the heater will be at full power regardless of the amount of available export power. This means that power may be drawn from the mains grid supply during boost times. - Page 13 (See Priority on page 19). If one or more boost times conflict for one heater, the boost will follow the latest time or longest duration. Cancelling Boost The boost can be cancelled at by pressing twice during a boost. eddi operation and installation manual...

The date and time are used for the Boost Timer and the savings calculations and therefore should be set correctly. In the event of a power-cut, eddi will still keep track of the time and date for a few days, so when power is restored the clock will not need to be reset. -
Page 20: Advanced Settings
Supply Grid - Phase The Phase setting is only used on 3-phase systems. It should be set to match the phase number that the eddi is wired to so that the power measurements are correct and that eddi responds to the correct phase when using the harvi wireless sensor. -
Page 21: Linking Devices
– An self-powered wireless sensor that can be used along with myenergi load controlling devices such as eddi zappi and is able to report the grid or generation power information to the other devices wirelessly, this can greatly simplify installation. - Page 22 Device Priorities The priority of each, load controlling linked device, can be set from any device with a display. This enables control of how the surplus energy is shared between them. The example below shows one eddi device, two zappi...

Page 24: Wiring
Supply The eddi device should be connected to a single-phase 230V or 240V nominal AC supply. The supply should be from a dedicated 16A circuit breaker, or it can be from a hard-wired 13A fused spur outlet if the heater load is less than 3kW. - Page 25 Installation eddi operation and installation manual...
-
Page 26: Sensor Installation
Grid Sensor must be on the same phase. If the generation is also three-phase and it is desired to consume surplus power on each phase, 3 eddi units can be installed provided there are suitable loads. Note: it is usually possible to split a 3-phase heating element into 3 individual elements by removing the links. - Page 27 In some cases it can be difficult or impractical to install a wired sensor. For example it may be the case that the eddi unit needs to be connected to a sub-board, rather than main consumer unit and two consumer units are in different buildings.

0.0kW). Note; however, if the surplus power exceeds the rating of the heater then this cannot be achieved and some export power will be observed If power is being imported from the grid when the eddi is in Heating mode, it is likely that the Grid Sensor is improperly installed - see Grid Sensor Installation on page 26 If a Generation Sensor has been installed, the generated power will show at the top left of the main screen If the generation reading is missing, the most likely cause is the CT2 input is not enabled –... -
