Page 6: Box Contents
If you have any concerns about the wireless performance then we would be pleased to answer your questions, but please consider that if a WiFi signal works OK then there is a very high probability that the myenergi devices will also work without any issues. -
Page 7: Ethernet Or Wifi Connections
All myenergi internet capable devices should be connected to the internet via either WiFi or a hardwired Ethernet connection. This version of the eddi can also act as the “gateway” or “hub” between all your myenergi devices and the myenergi server. The gateway device MUST be connected to the internet. -

8. Installation Mounting NOTE eddi is NOT suitable for installation outdoors Ensure the device always has adequate ventilation; do not block the vents or obstruct airflow at the back of the unit. eddi must be fixed to a flat vertical surface using the dedicated mounting bracket which comes attached to the unit. -
Page 9: Wiring
Wiring WARNING! ELECTRIC SHOCK – An electric shock can be fatal; electrical connection work may only be carried out by a competent person. The earth conductor must be correctly installed and reliably connected. This device must be equipped with an over-current protection device of maximum 16 Amps (B16). Only purely resistive loads must be connected to the Heater output terminals. - Page 10 Page 10 of 36...

Page 11: Ct Sensor Installation
CT can be wired to the nearest device. Note: The harvi device can be used if it is not practical to connect any CT to the eddi. NOTE If a myenergi zappi EV Charger is configured it is not G100 compliant to use a harvi to measure grid CT. 8.4.1 Grid CT The Grid CT sensor (supplied) needs to be clipped around either the Live or Neutral meter tail of the electricity supply meter. - Page 12 Refer to the harvi installation guide for details on installing and configuring harvi for your system. NOTE If a myenergi zappi EV Charger is configured it is not G100 compliant to use a harvi to measure grid CT. 8.4.5 CT Golden Rules – Grid CT Only ONE Grid CT per phase (check for only one ~ symbol in Linked Devices Info).

Page 13: Advanced Installation Options
Load Balancing/Current Limiting/Load Curtailment CTs can also be used to limit the current drawn by myenergi devices to avoid overloading circuits; this is referred to as load balancing or load curtailment. There are four different ways to limit current and they can be used alone or combined for more complex situations. - Page 14 The CT should be clipped around the Live cable of the supply feeding the diverter. The arrow on the CT should be pointing away from the diverter. Wire the CT to the nearest myenergi device or use a harvi unit if wireless connection is needed.

Page 15: Relay & Sensor Board
Relay & Sensor Board eddi has the option to install a Relay & Sensor Board (available separately). This allows for many different wiring configurations and includes the following features: Two independent multifunction relays (16 Amp) eSense input (isolated 230V detection for economy tariff etc.) Two temperature sensor inputs (PT1000) The two relays can be independently set for several different functions, or they can be set to operate as a pair. -
Page 16: Fitting The Cover
Step 3: After the eddi starts-up for the first time, there will be a start-up wizard. There are two likely scenarios here. Either this is your first myenergi device or you are adding this device to an existing myenergi home eco-system. -

IF IN DOUBT… Contact myenergi Technical Support – support@myenergi.uk 10.1 Dual Element Water Heater 10.1.1... - Page 19 10.1.2 Functional Description Electric only households tend to have a hot water cylinder with two immersion heaters, this is perfect for eddi as it can support heating two heaters sequentially. Heater 1 (the top immersion heater) (4) is heated with surplus power until the water at the top of the cylinder is hot and the thermostat opens, then eddi will immediately switch over to Heater 2 (6);...

Page 20: Economy Tariff With Dual Rate Meter
10.2 Economy Tariff with Dual Rate Meter 10.2.1 Key for Wiring Diagram 3 eddi device Mains supply (230V AC from B16 circuit breaker or 13A fused spur) Hot water cylinder Heating element 1 (max. 3.7kW) Isolator (20A double pole) Relay & Sensor Board (optional add-on for eddi) Temperature probe (type PT1000) (optional) Economy rate electric sense wiring (live only when economy rate is available) Heating element 2 (max.3.7kW) - Page 21 10.2.2 Functional Description It is common for electric only households to employ dual tariff billing. This application enables automatic heating of water when the economy tariff is available whilst also using any surplus generated power to heat the water. The economy rate electricity can be time based or random, in either case, eddi can be set to heat the water at the economy rate whenever possible, or at the economy rate only during certain times.

10.4 Underfloor Heating Mat and Water Heating 10.4.1 Key for Wiring Diagram 7 eddi device Mains supply (230V AC from B16 circuit breaker or 13A fused spur) Hot water cylinder Water heating element (max. 3.7kW) Isolator (20A double pole) Relay & Sensor Board (optional add-on for eddi) Temperature probe (type PT1000) (optional) Mains supply for underfloor heating controller Underfloor heating mat (max. - Page 25 10.4.2 Functional Description As well as water heating, eddi can be used with electric underfloor heating mats. In this application the water is heated as priority and when fully heated, the surplus power is instead diverted to the underfloor heating mat. Heater 1 (the immersion heater in the hot water cylinder) is heated with surplus power until the water is hot and the thermostat opens, then eddi will immediately switch over to Heater 2 (the underfloor heating mat) (9) and continue diverting the surplus power.
