I am trying to make sense of an installation at my daughter's house.
The meter is Heatwise.
Looking at the wires it appears that the meter also switches the circuits
on
at the appropriate time.
Not sure about:
1. The Boost Button. (is this a manual additional boost to the circuit at
normal rate)

Probably.

2. The separate fuse.

The low-current feed from the meter to the contactor coil.

Not sure if the fuse has an outgoing cable. Do you think the heater circuit
is directly wired to the meter?
