New wireless receiver install and no hot water S-plan
Hi,
I've installed the wireless receiver today, my heating is s-plan. The heating portion of the system is working as expected but the hot water system is unable to switch on. I've verified the physical connections are working correctly by bridging the hot water to live (my setup is live + neutral for power and a single connection each for enabling radiator heat and hot water heat).
When I try and configure the system type by holding the radiator and hot water test buttons it appears to think it's a combi system. Reconfiguring to green doesn't appear to work, the lights flash in the correct sequence but the white fault light is shown briefly and it appears to revert to combi mode.
I've found that if I unpair the receiver from the internet bridge and try reconfiguring to the green s/y-plan setting the test buttons work and I can request hot water for the 2 mins of the test cycle.
As soon as I pair with the internet bridge it appears to revert to the combi mode again and I cannot request hot water.
Has anyone had the same experience with their setup and know of a workaround?
It seems to me that there is something incorrectly automatically configuring my system to combi once it's paired with the internet bridge.

I had the same issue when I installed a few weeks ago. As I was upgrading from a V1, I put it down to an installation error resulting in me not removing the V1.
I worked around by retaining the V1, which is running alongside the V3. The V1 still controls the heating and HW and the V3 also runs the heating from its separately located sensor. As I ended up with two working stats, I decided not to pursue it with Tado for fear they’d break it, but now you have me thinking there’s actually an issue with the receiver.
Assuming you don’t also have an older Tado system available to run in parallel, you could still mirror what I did to run your HW until Tado fix it. I simply wired the V1 back to the V3 receiver (rather than the wiring centre) so that the V1 takes L and N from the receiver, then sends SL back to the output connectors in the receiver (eg HW NO).
I assume you’re still waiting for Tado to answer your support ticket?0 -
Thanks DM932187, that got me thinking and searching around a bit more.
I've been able to solve the problem - I had already installed 3 TRVs + internet bridge and I was adding the receiver from a seperate wireless starter kit. As the TRVs do temperature I had assumed it would all work and I didn't need to use the wireless temperature sensor that comes with the wireless starter kit.
Now that I've added the wireless temperature sensor the hot water has magically started working correctly.
Doesn't make a lot of sense but I'm happy it's now all working correctly.0 -
Glad to hear you’re sorted, and that’s at least reassured me that it might well be the locked in presence of the V1 in my system preventing the V3 receiver taking on the HW. (Ie, as I can’t remove v1 from HW control, v3 thinks I have a combi).
May take it up with Tado when the spring comes so I don’t lose heating. Should probably raise the ticket now then…0
