Soz forgot to say, yes i had the existing programmer set to 24/7 but just feel we are burning a lot of gas ..... it isnt a massive property and we are in and out throughout the day so having it running all the time just seems inefficient. Regards the Nest schedule I am correct in saying it will...

Again thanks for a comprehensive response. So my existing setup Combi + Programmer + Nest Thermostat will not operate how I am wanting it to through the NEST schedule feature i.e. it switches on at pre-defined times and durations like it was setup on the original programmer ? You also mention...

Out of curiosity I tried using the old thermostat wiring and the heatlink appears to work i.e it will regulate at the set temperature but what it doesnt seem to do is switch off or on. Have i misunderstood what the Nest does or as you say do I physically need to remove the existing controller...

Doh .... I didnt quite think that through .... :) So what is connected presently is power boiler and power to the controller from the fused switch and 1 and 3 to the boiler in the loft ?

I doubt i would benefit from anything overly complicated. Its a pretty small semi-detached and we usually just have the heating to come on for an hour or so 3 times a day.

Hi Flameport, Many thanks for the response. So literally take just the wires 1 and 3 from the controller back plate and connect those to the heatlink and blank off everything else and job is done ? I assume blank of the fused timer/boiler switch to the left of the controller too ? Any idea what...

Hi Eric, Thanks for the response. Do you think i am better just doing a straight swap for the controller with the heatlink ?

Its the Nest Thermostat E btw

OiOi DIYers I am looking to install a Nest Thermostat in the house and need a bit of guidance. I have a logic 30 combi boiler in the loft a controller in the cupboard downstairs and what i think was a room thermostat for a previous under floor heating installation in the living room. Can i...

I assume this is the correct battery: https://www.intamicro.co.uk/p-720-scantronic-500r-alarm-panel-battery.aspx Should I just get that and then re-program .... or should I try a re-program first just to make sure ...... and if it is a re-program .... do I need to open up the unit and...

Thanks all for the prompt responses. Should note that we have not encountered any issues until very recently. So you reckon its just wild coincidence that we all have alarm issues (not the same; theirs repeatedly went off whereas mine didn't work at all ) at the same time and a break-in? Can...

I personally have not changed it .... its wired to the mains though I think ?

Recently a neighbours house was broken into. I then realized that a couple of elderly neighbours had also recently complained about issues with their home alarm systems. My own alarm system also seems to have suddenly stopped working properly for some reason. It has managed to reset its self...

Yes from what I have been told ariston parts are as easy to get as Jasons Golden Fleece. Using it incorrectly ? i struggle to accept that tbh .... I have never seen in any manual instructing people not to have there radiators low etc. or do not operate the system at maximum ...... if it...

Appologies if it isnt clear: Its a semi-detached so everything on the other side is is my neighbours but I can get a pic of that if you think its necessary. Was in a rush to get the photos up onto the forum so never had time to re-size. On that picture of the existing dormer is the main...

Anyone ? or am I in the wrong section again ?

Any idea how much that would cost me? 1) System Bypass Valve - he reckoned an hours labour 2) Room Thermostat - no idea about this I am beginning to wish I just let him change the thermistors now. I had just thought he was being a bit hasty but going from above it looks like replacing...

Just as you said modern boiler but parts were a joke.

he was actuallly going to change the thermistors out but as i have said before the conclusion was the lack of a bypas was the issue. Shouldnt he have known it was built into the boiler? It concerns me that the 2 faults you had appear to be the exact same issue as mine .... possibly ...
