I like to do things myself when I can, but when it comes to electrics and such, it's very much a "like for like" like replacing wall sockets with ones with USB chargers, or an old electric hob with an induction hob, for example as I don't really get the ins and outs.

If it really is a case of doing what I described above then awesome, but if not then I'd rather know before I started! I already have Lightwaverf lighting and a hub but their support is poor and the app so flaky I don't want to go with them for the heating controls, particularly given the poor reviews they have on amazon. Last edited: 30 Nov The wiring behind the Sunvic There are different versions of the Sunvic Select, but looking at the wiring in your photo, it would appear to me that yours is as per the model detailed below.

These details will be in the installation instructions for it, or printed on the back of it somewhere for you to check and make sure. If it is the same as the above, then the Hive Single Channel version will be a straight swap as you can see from the drawing below the connections correspond terminal for terminal.

I'm assuming your Worchester Greenstar CDi 30 is a combi boiler version that provides hot water on demand, so doesn't presently have any time control for hot water. When you install the new thermostat, there should be at least one radiator in the room where the new thermostat is fitted that doesn't have a TRV fitted to it. Otherwise it could interfere with the operation of the new thermostat and stop it working properly. Thanks x 1.

Thanks for the quick reply! That first diagram is indeed on the back of the timer it's a XL, now I see the label on the back although it says fused 6a, rather than 3. The Greenstar CDi 30 is a combi so no need for water, no. I'm wondering how best to situate that given my setup.

My place is a pretty chilly old cottage and I live alone except on occasions the girlfriend is here and the heating has to go up everywhere! At night I turn the office TRV down to 1 and the living room up to 2 or 3 doesn't need more as it's the only properly insulated room.

I guess I should put the thermostat in the coldest room hallway in the house so it would only go off if that place hit the target and keep using the other TRVs as normal? Does that make sense or is my logic backwards? Looking at your picture, is that a universal backplate?

If so, where can I buy a new one? Thanks Pete. They are supposed to be universal but can be a bit tight occasionally.

The Hive will come with one. Thanks x 1 Like x 1. Last edited: 4 Dec
