Until just recently I used to have an electrical supply meter which controlled my storage heaters & hot water via a remote wireless signal,
a service which is being discontinued, so now I have a smart meter.
Today I was examining the labels on the switchboards to check how the
wiring is laid out around the house, and I noticed on the (formerly
remote switched) heating/hot water switchboard labels reading ...
Water Heating 24hr Supply T.C. Storage Heating
... which of course have the relevant circuit breakers below. The
middle label has underneath things that are human controlled, the
shower, bedroom heater panels, etc, so "T.C." can't be "Timed Control"
as I first thought. A Google search threw up literally nothing. Can
anyone here enlighten me as to what T.C. stands for?

IrCOm not sure I entirely follow your post, but why not Timed Control? If the output of that breaker went via the Teleswitch it would indeed be timed control.

Because the appliances in that section - immersion heater override, shower, bedroom heaters, etc - are not under timed control, they're controlled by the occupants of the house, see:
<www.macfh.co.uk/Temp/Mains_Switchboard_-_Timed.jpg>
There are three sections labelled as above and also as A, B, C ...
A circuits - Storage Heating (timed control)
B circuits - 24hr Supply T.C. (human control)
C circuits - Water Heating (timed control)
(Note: In the photo, the immersion heater is currently not connected
because of ongoing work in the bathroom.)

Some sort of "Circuit"? These labels appear to be standard with "L"
numbers so perhaps look for an old Wylex catalog?
Why on here? try
uk.d-i-y?

I gave up subscribing to that ng a long time ago because it was too full
of right-wing political BS and the actual d-i-y advice itself was either rather obvious or else when it wasn't didn't seem to be very useful; to resubscribe now would mean wading through a load of back posts. While
I'd like to solve this little mystery, I can live without knowing the
answer if I can't.
