I have just bought a tempus 1 programmer and need help with the wiring please. I have a Live, Neutral and earth with a yellow and white wire coming from the wall. The timer has a slot for the Live, Neutral and earth so I know where these go however I'm not sure about the yellow and white. There are 4 more slots numbered 1, 2, 3 and 4. 1 is COM, 2 is Off and 3 is On and nothing for 4. What do I do please? I am not sure about the yellow and white wires and where they go. Is this standard central heating colours?

If it is, then put the two rouge cables across com and on (either way around)
