Changing two way switch to two way dimmer

[willisons]

My hallway and landing can be switched on from downstairs and upstairs from 2 gang 2 way, however, I would like to change the downstairs switch to a dimmer. From the back plate I have three main wires:

1) Earth, Yellow, Red, Blue

2) Earth, Yellow, Red, Blue

3) Earth Brown, Blue

The dimmer I have purchased is Hamilton Hartland and made to BS EN 60669-2-1. I have only three terminals - C, L1 and L2.

Please advise if necessary I am willing to chat on the phone.
