Salus 500 to Worcester 24CDi

[Hubert]

Hello, I just picked up salus thermostat. Is there anyone out there that's using it with one of the old Worcester boilers like 24 or 28cdi? I never took it apart and I could use some instructions on where the wires are. Manual provided with salus is pretty clear but I find it difficult to locate the cables inside my boiler. Any advice would be great. Thank you
