Help changing a timer

[gash2024]

I have a Danfoos 103 timer at the moment http://www.danfoss-randall.co.uk/Si...l7ID=&intLevel8ID=&intLevel9ID=&intLevel10ID= but i want to replace it with a Siemens RWB9 but iam unsure about my system type on the diagram,Choices are Gravity,Mid-Position and Zone (think its gravity but not 100% sure) and which wires going into which ports.
current wiring into the Danfoss 103 is

2 red& 1 brown into No 1
Empty No 2
Red wire going from No 3 into No 6
2 Earth going into Earth
2 Black& 1 blue No 5
1 red from wall and 1 red from No3 into No 6

All iam looking for is someone who can help me put the correct wires into the siemens timer please
Many Thx

Need some more info , have you a room stat , a cylinder stat, any motorised valves ??????, on your existing timer 5 and 6 are your live and neutral mains feed 3 is linked to the mains on 6 and when your timer switches on it provides a live to no 1 which sends live to your boiler and pump and/ or motorised valves , it doesnt sound like you have a mid position system , it sounds more like a basic system with possibly gravity hot water and pumped heating or possible pumped heating and pumped hot water.

Room stats either need a 3 wire or 2 wire connection (excluding earth). One wire is the switched live in from the programmer, one the switched live out to the boiler/pump and the third is a neutral to connect to the accelerator in the stat (if there is one).

If both your old and new stats have accelerators then it's a straightforward swop. If the old does but not the new, there may be an unconnected terminal to park the neutral wire safely. Read the instructions!
