Landis & gyr E470 ...how to read

Matthaus73

I have the E470 meter (no longer smart) with IHU. Is their anyway I can read what kwh price it is programmed with and can I change it my self to my current tariff?

You should be able to see the tariff set in the meter in your IHD. Users cannot change any of the settings in a smart meter. If you have moved to a supplier that doesn’t support your meter, then what you are seeing is most likely the previous tariff cost per kWh.

I have a Landis & Gyr E470. Changed supplier via MSE to Symbio Energy, who don't do smart readings, eventually found out how to read using A&B buttons, but for the past three months the 01 reading is stuck on 02829kwh. Have reported this to Symbio several times without reply. Going through the menu I find "ALC5 on or off".  Does anyone know what this means? Thanks

ALC = Auxiliary Load Control. When talking about L&G E470 meters you need to specify which model as E470 comes in a number of varieties: non smart; SMETS1 and SMETS2.

I'm guessing that the meter is capable of offering a peak and off-peak tariff and the off-peak facility (ALC) has been turned off - did the place once have off-peak heating. The O1 reading was probably the off-peak register which is now inoperative.

How many cables are there entering the bottom of the meter. Most have four but those that can switch an off-peak circuit will have a fifth which would be the Auxiliary Load Control - it could either be a fat cable, around the same size as the other four and would then feed a second distribution board for off-peak heating and hot water or a thinner cable which would then activate a contactor to switch the off-peak circuits.

For SMETS2:

Auxiliary load control switches (ALCS)

Large domestic loads like storage heaters or heat pumps can be connected and controlled independently from a consumer’s main supply. An ALCS inside a smart meter can switch the electricity supply to the devices connected to it on or off based on an agreed switching pattern. It works in the same way as today’s Economy 7 meters, providing a scheduled period of power to connected devices, but, subject to an agreement made between a supplier and consumer, could also support ad hoc commands allowing switches to respond to wider network conditions such as periods of excess renewable generation.

AFAIK, the only supplier that is offering this - in a very limited way - is Octopus.
