Economy 7 Supply Control.

Zoomup
Evnin' All,

                   at today's first job I came upon a strange thing, well for me anyway. A house has economy 7 storage heaters, no gas present. The Economy 7 supply is controlled by a loud buzzing contactor that makes a big bang when it operates. It is situated near to the meter but is controlled by a simple 24 hour time switch that might as easily control an immersion heater. The time switch can be altered by the house owner, as well as being manually turned on and off.


Why this arrangement, and not a proper Economy 7 timer switch or teleswitch.?

    HAN (Home Area network) is the radio interface between the smart meter and that silly display thing that is supposed to tell you consumption and tariff info, but actually flashes "searching for network"  for a bit and gets put in a drawer after the novelty wears off.


    The expectation is that other devices will eventually be made and sold that can join the same  (zigbee format) radio network that are a bit more useful and can be put beside a water heater or whatever to close some contacts to select a different thermostat or whatever when the tarrif is changed.


    how  well this works once the spectrum gets a bit more congested is anyone's guess.


    Smart meters have two radios inside

    - one to talk to the suppliers 'wide area network' or WAN - this is either a mobile phone like interface or an 800MHz proprietry thing depending where in the UK you are based.

    - and the second 'Home area network' that interfaces to the customer.
