Adding a pipe stat to an external boiler for frost protection
Is the following wiring correct for adding a pipe thermostat alongside a heating controller so both can fire up the boiler (ignoring electrical sources which are already present at all locations)?
Note: the boiler only requires L/N/E connections as it's a heat-only boiler (i.e. it "only contains" a burner and heat exchanger)
