It's for an external temperature sensor, for use with weather compensator controls.

Should this not be asked in the combustion chamber as it is embarrassing a diyer having to tell a pro .
How is the registration going Agile has it came through yet

I would like, with all due humility as a lowly diyer, to draw your attention to FW100 Installation Instructions. It give the NTC resistance on page 10.
PS It was well and truly hidden on the WB website.

Thanks for that Hailsham, its exactly what I was after !
Its not long ago that Worcester did not have any W-C for their boilers and they certainly do not publicise it. A year ago at the show when I asked on their stand they said "there is no demand for it".
Seeing the connection on the boiler made me ask the question as the MI for the boiler does not mention it apart from showing the connection point.
However, there is still an inconsistancy as that connection is on the boiler PCB whereas the FW100 controller seems to have the outside sensor connected directly to it.
Can anyone through further light on this question?
Has anyone used W-C on a Worcester boiler either with or without the FW100 ?

Figs 14 and 15 both show the NTC and the FW100 connected to the PCB.
OK thanks.
Odd design concept though.
That means that its unlikely to be able to use W-C without the ( expensive £163 ) FW100.
At least its available which is giant step forward for Worcester. Such a pity they dont make it a selling point for their boilers as Vaillant and Viessmann do.

your not on glaziers iggy list are you namsag?
whats all this about his registration? dont tell me the man with the stiffest rod up his back is working illegally?
Actually, not so long ago, Worcester announced how they were going to fund independant research into WC, its uses and realistic cost savings.
The following month they released their range of WC controllers with no mention of the results of the research!
More WB marketing sh1te. What a surprise!
Hi Tony,
I have only just seen this thread as i havent been on here for a while.
Any way yesterday i installed a WC to my 42CDi combi, as i want to be able to set one up and use it to its best ability before i visit one of our customers that have had one installed. As you have mentioned you do need both the fw 100 and outside temp sensor.
I must say i had training on it ages ago but have forgot all that and to be honest the trainer wasnt that clued up on it either, so im intending on learning myself, there isnt many people in our company who are fully clued up on it as its quiet new technology to us Brits, hence a few of us are installing them in our homes to become familiar with it.
From what i understand after 1 day using it, ( the installation instructions are a direct translation from German and someone soon is going to sit down and re-write them in more simple terms) the fw 100 can either be mounted on the boiler facia or better still wall mounted as it can them monitor the room temp. If mounted on the facia it only works out the flow temp using the outside temp, if it is wall mounted it works out the flow temp uusing actual room temp and outside temp(apparently more efficent and better comfort).
you do need to set the parameters in the installers menu, by pressing the menu button for 3 seconds, my heating system has been designed with a max flow temp of 70 degs and an outside temp of -3degs, so i have entered this information on the fw100. It comes with it preset to -15degs and flow 0f 75degs.
one of my colleagues has had one in his house for a few months now and said there is a few complaints you could receive if you dont set it up to the individual system design.
1, set the heating flow temp to what the system is designed for otherwise it will never get warm enough in the property, mine is 70degs, older system were usually 80-83 degs. on my system it should be 70degs flow temp when the outside temp is -3degs
2, change the freezing risk outside to between 0 and -5 degs otherwise the pump will run continually(its preset to 3 degs) i put mine to -3degs
3, set the minimum outside temp to what the heating system was designed for mine is -3 degs, older systems were usually -1
4, customers usually find it hard to undestand the night set back or economy temp (preset to 15degs) if they want the heating completely off set it to frost protection (5degs)
5, the pump runs continually when the boiler is in comfort mode, something to do with load compensation, i havent got that far yet??
Its my first day using it and i find it hard not to want my programmable roomstat back, but im going to give a full heating season to try and pursuade myself to get use to the apparently increased efficency and comfort. It could be the future?? lol
I also havent read the manual fully yet, hope this helps a little, any other questions feel free to ask

Thanks very much for that, you cannot imagine just how helpful it is to me now that my customer has agreed to have the WC.
Unfortunately you help has shown up just how unhelpful your firms tech help was when I asked them!
I will order it this week and then install it perhaps next week.
One question for you though, when fitting it outside the boiler what cable does it need? i.e. how many conductors?
Thanks very much
Tony

I have used 2 core cable 075mm dia for both the sensor and fw100, in the installation manual it will tell you the different diameters maximum lengths. its advised to use shielded cable if it runs next to 230 v ac cables.
If you ring the tech helpline and ask for someone that is an expert on the weather compensator you might have better luck, as most people dont know much about them, including me before i fitted it on the weekend.
Now i have it installed in my own house i am pleasantly suprised with the way it works, my Cdi combi and fw100 has been set up for my individual heating system though, way more indepth than the average user would do.
Dont forget to set the fw100 to the system design otherwise you will probabaly get complaints. The one observation im not to keen on is once the room temp is reached the pump will keep running as long as its in comfort mode and another thing worth noting the room temps you set for comfort/frost/eco are not the actual room temps, just a guide??
Its frustrating for me as well, as i would like to know exactly how it works in depth but they havent re written the manual in simple terms. There isnt a demand for them so i imagine its not on the priority list??

There IS a demand, OK not a vast demand at the moment as the more knowing installers have moved away from Worcesters to boilers where WC is an acknowledged feature.
As Viessmann tend to be fitted by the more discerning RGIs, I am getting the impression that at least 10% of them are being fitted with WC at the outset.
Thanks again
