The old one has a single'block' on the back with 3 terminals top and bottom L1 L2 and com.
New one has two 'blocks' with an L terminal at the top of each and L1 and L2 at the bottom of each.
There are 4 incoming cables, 2 have a red and a black wire and the other 2 have a red and a green.
How should I wire the new one please
Any help gratefully received.
