I've got a Drayton RTS1 replacing an old Randall unit. There's 4 wires wired up as follows, Yellow = 1, Blue = N, Red = 3 and Green is Earth; 2 is empty:
The new unit looks like this, Obviously neutral is self explanatory, 3 I'm guessing goes to 3 on the new unit making yellow "live" ?
If anyone can confirm that would be great.
Cheers
