The message
from "Doctor Evil" contains these words:

2 * 2-port valves etc, but you'll also need a bypass (e.g. pressure
relief bypass) so when the last valve turns off and tells the boiler
to
stop theres somewhere for water to go while the boiler keeps the pump
running as it cools down

That is only if there are rad valves on all rads. If the rads do not
have
rad valves there is no need for it, unless the maker states one for heat
dissipation reasons.

Am I being particularly dim this morning

You are dim.
