I think The Builder helped me earlier this year when our new boiler was installed. It was all set up and it works quite well and very quiet unlike our old Potterton but just one problem........

When the engineer set it up I asked him to set the temp the same as old boiler ie 72 degrees as we like our flat hot and have the heating on a lot. However I notice that it does not always show 72 when it has reached it's heat and often shows 76 of 80! Does this matter? Is there a setting for this on front of boiler as I see two buttons left and right?

Also they fitted a Center digital timer on wall which I have mastered at last but can you tell me if this will automatically change the clock when clocks go back to Winter time?

Thanks so much

Are those figures CH water temp in centigrade or room temp in fahrenheit?

Even if the installers left you printed documents I find that having the pdf versions makes it easier to search for information.

Etch - sorted now from your PDF! Quite easy really.

Nothing about winter/summer settings so think may be set for automatic change

Thanks again

It will be C these days - 72 is quite hot (40-80) is a normal range. Whatever the setting it will shut off when the room reaches the thermostat setting but the hotter it is the quicker it will get to that temp & the more "overrun" there will be.

Anyway you got it sorted. Not sure about the time change tho'

Thanks your help davebro - yes I managed to set it for 72 (same as my old Potterton) as we like it hot and have our heating on a lot! Set the water temp at max as my wife likes water nearly boiling! What do you mean by run on - is that it means when occasionally it goes past the 72 setting?

I think I have mastered the Center TStat and know how to change the clock I thinks for Winter time. Engineer whi fited this new boiler said that the time changes automatically via wifi but think that is wrong as the only wifi connection is between the wll control and a little wifi box under boiler! Anyway I am happy with new boiler which is very quiet indeed.

Thanks again

Hello again everyone!

Just one further thing I do not inderstand (otherwise the boiler is working perfectly)

It is set to auto and it goes off at 10pm with the temp at about 25 as we have had it on in evening. Up until a few weeks ago it clicked on at 6.30am as set no probs but recently it does not come on! I know it is a bit warmer of late but what I cannot understand is once it goes off at 10pm I look at readings on Center stat on  wall and it shows current temp of say 25 but in above it it shows coming on temp of only 15.5!

What am I doing wrong please. Must I reset the 15.5 to make it say 27 for it to come on?

Sorry to have to ask again.

Thank you

Moggie
