How to Commission the NEW Vaillant Ecotec Plus Combination Boiler with it's New Touch Screen Display 

Thank you for this, I couldn't figure out where the reset button was after I had my gas meter changed. Much appreiciated!

Thank you Mark

With regards to filling, if you power up before filling it will enter purge mode whilst filling to clear air from the heat exchanger via the AAV. 👍🏻

Please help me I have a very simple control unit and my boiler won't heat the house up simply wont go over 18c⁰

What is DSN code for 826 boiler

Great video Mark! I get all installs are different, but what kind of cost should people expect for installing this particular boiler?

Hi Mark, Great very instructive video. I really enjoyed it. Small question. Can one use a timer function on the “home domestic water comfort function” (eg. from 07 am to 07 PM and then off) or do you have to change it manually in the app? Looking forward to your new videos.

Hi, Mark Thanks for the info. I have a question. I have Vaillant Ecotec Plus system boiler plus unvented cylinder. When the boiler is on, the radiator is working but there is no hot water. I have tried the DHW (domestic hot water) setting on and off seperately, but still no hot water. Wondering what go wrong, thanks

Many thanks Nice one

Would be great to see video of other Vaillant eBus controls such as the wiring centre for S Plan and Senso home thermostats, no one has put any up for some strange reason

Hi Mark, great video - thanks. I also bougt an ecoTec Plus a few weeks ago and when testing some things i put it into summer mode by pressing the heater button 3 seconds. My problem is that i use a Tado smart controller on the eBus instead of a Vaillant controller - Tado can not end the summer mode - will resetting the boiler to factory settings and configure it new based on the diagnostic infos end the summer mode on the boiler? And is there any risk when resetting to factory settings?

Nice one 👍

Thanks very good perfect

Weird things happening with out install (occurring as I type this) there is no option to set whether the boiler is using weather compensation, and under the diagnostic codes there is no option for 162, there is just 161 and 164. Tried a factory reset and nothing.

Hi Mark having installed a couple of the new 625 models we have had problems with them stuck on low flame so will only reach around 53c if we reset it will go to full flame and the next day it reverts back to low flame any idea's Regards Richard

Hello Mark, Can I replace my old VRC470/4 controller with a newer controller? Do they all work with 24V ? Do I need an adapter plug for the newer controller? I have a VWL 85/2 A heating/cooling system. Thanks.

Radiator mode has dash across it meaning it's off - how do you get it on ?

Is it the same price as its predecessor?

hello mister greetings from turkey i'm getting a vaillant ecotec plus f105 malfunction.could you please share information to solve the problem. thank you.have a nice day.

Hi Mark, what is the fault code F.105 about please? It reads "Gas valve offset incorrectly set" Please help 😬

The code is 17

Hi, where can I find enter access code ? Thanks

How do you undo the test point in the gas valve

Did they just take the sensoComfort and integrate in into the boiler?

What is the access code

F57 eroare?

They made an easy menu from past models into a tedious and long winded annoying one! Best keep the installer number hidden. Customers love to play around with boiler settings then claim they didn't touch it.

! N.100 please thanks

That code should be secret only for engineers to know

Be smart choose atag

17 installer access code

Be smart, choose Viessmann
