Thanks for the response.
The reason I connected "4" to "W" and not "2" was because of the "blocks" in the circuit diagram on the old thermostat. I assumed that the one between "4" and the switch was equivalent to the "load" between "W" and "L2" on the circuit diagram for the new thermostat...
No, I couldn't either.
When I googled TH147E, I came up with AUBE Technologies and the documentation on that website is the same as I've got from Wickes. The Wickes website only has a load of other makes none of which were available at our local Wickes, this was the only non-programmable...
I am planning to replace an old mechanical room thermostat with a new digital one. The old one had three connections, the new one only two.
Looking through the posts on this forum, it seems that I don't need the neutral connection anymore and it should be disconnected and tidied away.
