Hi. Can you help me locate thermostat on my old glow-worm back boiler. Is has a real flame effect fire on the front, and underneath it there are no control knobs visible
Dales-Electronic :

Hello My name is Ian ~ I am not on the site constantly so please be patient whilst waiting for responses to you queries

Dales-Electronic :

Can you tell me which model you have of back boiler is it ~ 40 45 50 54 ?

JACUSTOMER-ppeu9yo5- : Hi. No model numbers available, but I think I may have found the thermostat control. It is ared knob on the side of the gas gire saying "burner on" and "reset". Does this sound right?
Dales-Electronic :

No that is the burner unit, if you go to the left side of that you should see a box with a knob on it and what looks like a piece of thick wire coming out of it ~ have you got it?

JACUSTOMER-ppeu9yo5- : Only the gas fire controls are to the left of it. Should I remove the gas fore front?
Dales-Electronic :

OK this will be a bit hit and miss without knowing which model it is, can you follow the mains power cable and tell me where it goes to in the boiler ?

JACUSTOMER-ppeu9yo5- : There is a thick wire underneath but where it starts and ends is hidden by the fire front
Dales-Electronic :

OK if I send you a link to a group of installation manuals can you look through them and tell me which model you have got?

JACUSTOMER-ppeu9yo5- : Ok. The mains cable is not visible at the boiler. There is a nearby wall mounted switch
Dales-Electronic :

Here is the manuals, just see if this covers your model ~ come back to me if its in that lot, if not there are some more modern ones I have ~ Ian

JACUSTOMER-ppeu9yo5- : Ok BBU54/4 looks like the correct unit. Diagrams 5.6 and 5.7 show the user control. This looks identical to the knob I described esrlier because there are two LED's under it in the same position. Is this to control I should use to reduce the amount of heat being transferred to the water for heating?
Dales-Electronic :

yes this is the control that sets the temperature of the water

JACUSTOMER-ppeu9yo5- : Diagram 6.1 shows the writing on the user control and it definitely matches the knob on the side of my unit. Now I just have to establish how I should use it
JACUSTOMER-ppeu9yo5- : All sorted. Thanks
Dales-Electronic :

OK sorry had to answer the phone, glad you have sorted it out, now that you have rated me you can come back for further information at any future time free of charge. Have a good evening ~ Ian
