It seems that I have a new project to get to grips with - my wife already thinks I'm leaving her for the boiler :) What seems to have helped with my initial issue is changing d.000 from auto to 25.5kW, a post on another forum mentioned that the auto function on the Vaillants can be a bit...

Yes, I meant LPH. Okay, I've changed it all back. It's a shame that mode doesn't seem to work, as the reasoning behind it makes sense. I'm all for squeezing as much energy out of it as possible.

Sorry, that's why I had the question mark; in my head, i thought it would go gung-ho when first turned on, then modulate down once temp has been reached, but it seems to just stick at a partial setting for longer. I was very used to an old boiler, that had timer for on/off, and a dial for flow...

Thanks - I made the changes and it didn't seem to affect it. The pump stayed at about 1100rpm, and it was flowing at 56/46C. I've double checked and everything is set as you recommend. Could there be something overriding it?

It's me who sets the flow temp - the old boiler didn't have numbers or anything, so I'm trying to figure out what works best - and hoping for some condensing efficiency. It's a 1906 Vic/Edw house, with 5 beds - does that make any difference? Just rechecked as house temp has just about been...

I've had a look and it's showing a target modulation of 37%, the FT is set to (and achieving 50deg). Return temp is 43deg. It does seem to be running okay, unless any of those stats are worrying?

So I've given it 20mins, and it seems to be be behaving itself, as in the FT is as it should be. S.04 Heating mode: Burner on D.00 Partial load - Automatic D.005 Flow temp target value - 45deg D.014 Target Pump speed - not shown D.015 Actual Pump speed - 86% D.017 Flow or return temp control -...

The installer purchased the boiler, I thought that they should do any interfacing too. Anyway, the DHW appears to be fine, and yes, I can access the diagnostics. Thanks

Hello, I have a month-old ecoTEC plus 832. House has a 13 rads. We have a set FT of 45 degrees, and for the most part, it's been great, and we have a hive thermostat control. It doesn't adjust the FT depending on weather. Last week I noticed that the actual FT was 28 degrees, and the burner...

It just happened again. The wife was running a bath, before she turned the tap off, I turned off the hot water on the boiler itself, but left the tap running. I hoped that the water running through the HEx would stop it overheating. No luck.

Hi all, CH works fine, ticks over nicely, got us through the recent cold snap no bother. HW works, but when you switch the tap off, it causes the reset switch to pop. Happens more when the CH is on. 9 out of 10 times, hit the reset and you're good to go, but sometimes there is resistance and...
