Sorry this is slightly off-topic; please let me know
of any more suitable groups to which I should post this
question.
The manufacturer>s website claims it can use all economy tariffs.
So does it somehow "know" when to switch on and start heating
itself? How does it "know" what time it is? There are no visible
controls to govern what times to switch on and switch off, and
there is no visible clock or time-setting controls.
I>m in Manchester, UK, and on an Economy 7 tariff that apparently
is split from 22:30-00:30, 02:30-07:30.
I>m trying to make sure the things won>t come on in winter
at the expensive rate between 00:30 and 02:30.
Is some "signal" transmitted on the mains line during
night rate?

I should have added that I have a radio teleswitch next to
my electricity meter.
I believe that I have found the answer on page 5 of this PDF:
http://www.nationalgrid.com/NR/rdonlyres/A3B1EE3E-BD61-46ED-8D44-4F6D0F1E5A07/1410/Teleswitch_Demand.pdf
So it seems that there must be TWO mains feeds into my
flat. One unswitched, for most appliances, and the other,
switched by the teleswitch, which only comes on during cheap
rate.
So the storage heaters should be connected to the switched
supply, so they should only consume cheap electricity.
Please let me know whether this is correct.
Thanks.
