s plan

The S-Plan or Sabotage Campaign or England Campaign was a campaign of bombing and sabotage against the civil, economic and military infrastructure of the United Kingdom from 1939 to 1940, conducted by members of the Irish Republican Army (IRA). It was conceived by Seamus O'Donovan in 1938 at the request of then IRA Chief of Staff Seán Russell. Russell and Joseph McGarrity are thought to have formulated the strategy in 1936.

    S Plan, 2 Houses, 2 Pumps, 2 Programmable Controllers, 1 Shared Gas Boiler

    Is this possible? Do you just wire up the boiler as per the S-Plan Wiring Diagram, and wire the boiler switched live from both controllers? Do i need a bypass valve? How is this controlled....don't the boiler pumps stop when the valves close? Thanks, James.
