The left hand knob is the reset selector knob the next one on the right of it and to right of the lights is the central heating temp control knob , this one decides how hot the radiators get, turn it clockwise until it is near the extreme position. the rads should get hot enough so that you can only hold them for 3 seconds.

Hello petertheplumber Thank you very much for your reply, the lefthand knob onlt turns half way round

you mean the second to last on the right. there is a tapered black line round the outside and a mark shaped like a very squashed O on the handle the mark on the handle should be pointing down and to the clockwise right to nearly 9 o'clock.

 

[officegirl]

yes, the second knob on the right

 

[petertheplumber12]

and now that it is clockwise almost as far as it can go, how hot are the rads?

 

[officegirl]

the radiators are not very hot at all, you can place your hand on the radiators, and leave it, without being burnt, they are just cool.

How many rads have you got, and to save waiting for a reply, can you try turning off 2 or 3 or even 4 and see how hot the rads get. are there any rads getting hot are are they all the same? what is the temperature hand hot wise of the flow and return pipes? 1 on extreme left is flow, 1 on extreme right is return which should be the same temp as the rads.

Has PCB been changed recently?

 

[officegirl]

yes, old motherboard didn`t work, british gas changed the mother board

Get them back, it needs the pcb removing and the central heating knob turning into the correct position and putting back.
Engineer was obviously too busy that day to check it was installed correctly!

 

[petertheplumber12]

you didn't answer my question, not fair,
