You can replace any diverter with another make, but why the hell pick a danfoss? Utter garbage.
Go get a honeywell.
The wiring is one in one out, colours are just about standard (except for danfoss which uses brown and white while ALL other manufacturers use white)!
Some valves are five wire, some are four wire, the 'extra' in five wire is simply an earth.
