How to connect my Tado thermostat to my Vaillant ecotec boiler? Is it not compatible?

Well not impressed at all with the supposedly super compatible v3+ starter kit.
Got to the bit of the instructions for setting up the receiver which requires it to obviously to be wired to something on the boiler/ control centre (in my case a Vaillant ecotec 618 with VR 65 control centre which currently uses Vaillant ebus through a VRT392f programmer and receiver).

Every choice of component I make related to my boiler installation in the extensive list of kit in the Tado database says “not compatible”.
I have found some Tado information on enabling ebus control, but that’s not a lot of use when it doesn’t tell you how to wire things up in the first place!

 Very confused with the difference between the wireless receiver supplied in the V3+ starter kit and other references I have found to a tado extension kit!

it’s ridiculous that you can’t find this compatibility/ installation information out before purchasing, and how come OVO are promoting this apparent minefield?

Perhaps it’s to commit you to getting one of their engineers to professionally install it….something I would be reluctant to  do when I have no confidence that what I have been sold will ever work with my system based on my experience so far!

I wouldn’t mind but I actually got in touch with Tado explaining my boiler/hw system and they said it was compatible.

So why are the installation instructions so elusive?

I’ve passed on the comments you’ve made here to our Smart thermostat team, @croninsfc - as it sounds like the compatibility of the Tado starter kit with your boiler set-up hasn’t been made clear at every step of the purchase/installation journey.

 

I really appreciate that you’re now seeking a refund and an alternative thermostat solution, so please get in touch if you need any further help with getting the product returned and refunded.

 

For others considering a Tado thermostat with your type of boiler we’ve had this feedback from the team, you can also check this compatibility guide from Tado themselves:

There may be a previous thermostat which was wired using the ebus connection, providing further boiler efficiency. This is not supported on the Tado starter kit V3 that we currently sell. However, this starter kit can be installed on a Vaillant ecotec 618. The difference is that it should be wired using the traditional on/off relay. If you’re not sure how to do this yourself, we’d recommend getting a local engineer to fit it for you.

    After trying the Tado smart thermostat I returned it as it was incompatible with my heating system.

    OVO acknowledged that I had cancelled and acknowledged receipt of my returned thermostat.

    They even gave a refund for 2 months that had passed from trying the thermostat to returning it.

    However, they are still billing me the £10 charge to pay for the thermostat under the heading of “upgrades” despite the fact that I have no upgrades on my account!

    Anybody else had this experience of basically being robbed?

    Thanks for sharing this on the OVO Forum, @croninsfc - what a pain to still have those ‘Upgrades’ charges applied to your account. 

     

    Can you email the OVO Smart Home team to let them know, and they can get those charges stopped and reversed? Email address to use is: smarthome@ovoenergy.com. If you or anyone else would prefer to call, use our main Support team number and the Smart Home team can be sent the call: 0330 303 5063.

     

    If you go for the email route, feel free to simply link them to this topic to save you having to type anything. It just needs to be from the registered email address so that they can take actions on your account. 

     

    Out of interest, was it the manufacturer of boiler that meant the Tado smart thermostat was incompatible? I can see you posted a similar topic above which outlined your Vaillant ecotec 618…
