Look at the Honeywell Evohome system http://www.heatingcontrols.honeywell.../evohome-Main/ The site exists, but not with the www. I had a quick look, thanks, but that's overkill for me. And thanks to the others regarding isolating/regulating. -- Cheers, Rob |

how hot do you run you CH boiler
John Rumm used his keyboard to write :
However I just found this: https://www.vaillant.co.uk/downloads...ons-261442.pdf In its description it says: John - I am reading that as suggesting it would provide a single box solution for my being able to split my CH and HW temperatures. Do you agree? |

Do you agree? The quick look I gave it appeared to suggest that. What I am not sure of is how you would set the various parameters without also having some kind of controller in there... What timer/programmer have you currently got? -- Cheers, John. /================================================== ===============\ | Internode Ltd - http://www.internode.co.uk | |-----------------------------------------------------------------| | John Rumm - john(at)internode(dot)co(dot)uk | \================================================= ================/ |

John Rumm explained :

What timer/programmer have you currently got? Just a basic electronic one, with battery backup, with an override until next action, on for one hour when off on both CH and HW. If it will work, the intelligence for setting it has to be in the boiler itself, so it must signal the HW demand back to the boiler, via the ebus. The boiler does have ebus terminals. It also has terminals for the NTC outdoor sensor - Do you happen to know whether the NTC is a 10K or 100K? The manual for the boiler is here - https://www.vaillant.co.uk/downloads...ual-876622.pdf It has rather a lot of settings in there, monitoring options and fault codes. Unfortunately I cannot find any mention of suitable extra controls and options at all. As you suggested, there is no 'big picture'. |

Unfortunately I cannot find any mention of suitable extra controls and options at all. As you suggested, there is no 'big picture'. On mine all those kids of things can be set from the VR470, but I could not do it from the boiler's internal display / interface alone. Hence the suspicion that you would also need something like the VR350 to give you the access to the settings... (alternatively there is I believe PC software available to talk to the eBus for configuration and reading current state etc - so you could possibly "configure and forget" it that way). -- Cheers, John. /================================================== ===============\ | Internode Ltd - http://www.internode.co.uk | |-----------------------------------------------------------------| | John Rumm - john(at)internode(dot)co(dot)uk | \================================================= ================/ |
