I have bought a Distribution Timer Switch from Conrad and am confused by the instructions. I have contacted them but they are a German company so communication is a problem. They tell me to connect the power to terminals 1 & 2 (not bothered which is Live or Neutral) but on the output side I have a choice - 3 & 5 for an Open Circuit or 3 & 4 for a closed circuit.
My problem is working out which it is because the connection is to an Immersion Heater which doesn't have a switch but it does have a thermostat so, depending on how you look at it, it's both open and closed!
Does anyone have a definitive answer, please?
