Vaillant Eco Max Pro - Old Style System Boiler

[Viper Gas]

Hello All

Sorry to bother you mate but after much reading I came up with the following heating controls schematic. However a couple of items remain unclear.

1- how to wiring up this particular room stat
2- Confirmation on how to wire up the boiler dedicated pump earth , live and neutral (according to draYton wiring diagram pump is to be connected to terminal block as shown however after speaking with vaillant regarding this boiler it seems the pump should be connected to the boiler as shown by hatched lines. please confirm)
3- confirmation of boilers required switched live input shown coming from orange on the mid pos vavle

cheers

exactly where the wires go will be determined by situation.
is it easier to send all 3 wires to the pump direct from the boiler??
or would it be best to send a 5 core wire to boiler from wiring centre (L,N,E,Switch L to boiler,L to pump)??
