we’ve not heard of anyone reporting issues with their ASHPs and a smart thermostat yet.

… and we still haven’t.

@Jsc referred to a breaker

So I assume we’re discussing one of these

but it could be a ‘breaker’ inside one of the major control units, which is why I’m asking for details.

@Transparent 

Hi yes it was the RCD. Required a type F that no local supplier stocked so had to wait for a special order from a manufacturer. Type Bs were available which I think would have worked for the variable load but they are more expensive.

With reference to the smart thermostat, can not see why it would not work. The wireless one that has been fitted has a similar receiver than the normal boiler smart systems. Problem at the moment is that the thermostat is calling for heat and the receiver is indicating it is sending for heat but the wiring to the system must be wrong as does not turn on. Heating is on with the daikin controller (the inbuilt room thermostat has been disabled).

Thanks @Jsc 

Ah… so you are convinced that the failure of the heating and the change of ‘smart’ thermostat a month earlier are linked events are you?

I had discounted that possibility as unlikely. Such a failure should’ve been almost instantaneous and therefore visible to the installer.

As for the RCD choice, I just happened to have covered that subject recently in the topic about Installing an EV Charging Point at home. Have a look at the table in the lead article.

If you had posted that problem here on the [color=#3b6889]F[/color][color=#298070]o[/color][color=#138b55]r[/color][color=#339931]u[/color][color=#54a03a]m[/color] at the time, then there are several of us who may have been able to quickly track down a type-F for you.

Even so, I don’t think other participants in the [color=#f07861]Heat pump Trial[/color] have a type-F RCD. Let’s see if anyone else responds here.

@Transparent thanks.

Have only just had the invite to the forum so a bit late in joining. The engineer installed it and set temp to 26 degrees and said it can take a bit of time to "kick in"! Northern gas did not know what they were doing.

It must be wired wrongly from the receiver to the system. Thermostat and receiver are showing calling for heat but pump not activating.

When I had the combi moved and installed by a gas safe, he was not up to speed with electrics so I installed the hive unit while he was there with boiler panel open. It is likely to be a misplaced call/live wire so should be easy fix for the engineer when he is next out.

I have not looked to see if they did install an F, was just happy to get some heat back in April.

I'll put some photos of the system up in the closed area.

Hi, we're part of the Zero Carbon Homes trial. It would be great to be able to chat to other people on the trial.

Howdy @M.isterW !

That’s a really ingenious name there! :D

I’ll go ahead and ask @Tim_OVO and @Jess_OVO for help with that, as they’re able to hand out the keys. Bear with us for a bit and we’ll keep you posted.

Feel free to explore the forum in the meantime. :)

Hi @M.isterW - great to hear from you!   

I’ve now given you access to the Smart Home Trials private area. You can browse, you can post your question as a new topic (here), or as a comment on an existing topic. For example, this one:

Also, I notice you’ve filled in your profile and have been an EV driver for more then 12 months. Nice! Fancy heading over to this thread next time you’re in an EV geek mood and consider leaving a review about your wheels?

You sound like you’ll fit right in over here on this forum!

Hi @Tim_OVO . I’ve tried the links you’ve provided but this one - https://forum.ovoenergy.com/smart-home-trial-treehouse-146/my-equipment-installed-for-heat-pump-installation-what-s-yours-9109 - gives me an error message “You are not authorized to access this page.”.

Sorry @M.isterW  - I suspect @Tim_OVO ‘s done a typo whilst entering your name in the Permissions List. That’s what happens if he tries to ‘work late’ on a Friday evening when he’s meant to be out buying drinks for the rest of the team!

Oops - bit of a Friday arvo slip-up there, @Tim_OVO!

Sorry for the confusion caused, @M.isterW - If you try again you should now have full access to all the Smart Home trials discussions including this one:

We’d love to see some photos of your set-up there if you’ve got some to share?
