No, Two counters (low & Normal) on the meter and separate 24hr
mechanical timer with clock work spring which switch over the meter and
switch on the E7 cables


Which is pretty much what is shown in the picture.... The E7 cables are
powered from a separate CU to the left of the meter board in this case.

The meter has two sets of readings and an arrow which indicates which is
currently in use. The mechanical time switch is to the right of the
meter. When it switches it signals the meter and energises the tails
that feed the E7 CU.
