Just took over a new property that has an EcoTEC pure 637 installed, separate HW cylinder, honeywell Evo home programmer (t6).
I'm upgrading and have bought the following items after doing a bit of research and would like to get some confirmation of my assumptions:
Purchased:
VR71 - I have a single heating circuit and HW, but would like the ability to add a 2nd in the future (UFH).
VRC720F - wireless Sensohome controller - I want to use weather compensation & load compensation for efficiency.
VR921 SensoNET - gateway to allow us to control the heating whilst we're away from the home or via phone/tablet.
Assumptions:
1) All the above, plus the boiler are able to be daisy chained for eBUS (i can insert two sets of wires in the same connection allowing eBUS to be linked onwards (see diagram).
2) Using a VR10 sensor that comes with the VR71 this can be used in the pocket of the HW cylinder to monitor/control temps of HW.
3) The wireless temp sensor that comes with the SensoComfort rf will allow me to use weather compensation.
Questions:
1) Will the above actually allow me to lower the HW cylinder temps, but retain a boost to kill off legionella every X days/weeks etc?
2) Is there anything else I am missing?
3) In the future, should we go for individual TRVs would there be any other modules I might need to purchase?
4) The VR11 that comes with the VR71 isn't needed in my set up.
5) If I wanted to add a secondary circulation pump, would this be easy to connect to the above?
Thx
