6. Save Energy with Intelligence INTELLIGENT IMMERSION Do you have solar PV panels or a wind or water turbine Now you can heat your water free An Intelligent Immersion diverter is a small all electronic device for your home that rather than exporting your surplus power to the grid diverts electricity from a microgenerator such as solar PV or wind water turbine to an immersion heater or other heating load Using clever internal software it modulates the heater current to exactly match the house load and PV generation thus delivering maximum power into the heater and a tiny power to the grid It responds to changes in house demand or generation instantly so is always matching what the house is doing It is fully automatic and needs no owner adjustment or interaction Indicator lights on the unit tell you what it is doing and how much electricity is passing to the load and the grid The thermostat in your immersion keeps the water to the right temperature There are two models available The I2 is the standard one and the I3 incorporates a Wi Fi interface so it can communicate with phone tablet and computer devices in an Internet of Things to provide increased functionality This datasheet is for the I3 see the I2 datasheet for the other model and for more information about the I3 s controlling of an immersion and its multifunction relay Compared with the I2 the I3 adds e Remote reading of up to 4 energy flows e

10. ils above Note 2 The I3 relies on an active Wi Fi and internet connection to collect the energy Statistics and enable remote control from outside the house Any loss of reception will cause gaps in the saved data Generally the I3 has better reception than a typical Wi Fi phone or laptop as it has a better transmitter receiver and aerial Thus if your laptop or tablet has adequate reception at the intended I3 mounting location then the I3 should work as long as the Wi Fi router remains active If your reception is poor we recommend an additional aerial Save Energy with Intelligence 03 15 Save Energy with Intelligence or Wi Fi slave access point The I3 Supervisor app will not need an internet connection to work and can be placed close to the router for connection reliability Note 3 Performance and payback times are not guaranteed Because every house is different in its amount of sunshine size of PV system use of hot water and electricity etc we can only provide indicative figures We can say though that the I3 performance is as good as or better than any other proportional diversion controller currently available and much better than any that only switch the load fully on and off It is equivalent to a medium sized solar thermal system at a much lower cost London is reasonably representative of average English and Welsh sunshine but the North of England and Scotland will have less in most locations THE COMPANY Who is behind Intellig
