I would like to thank everyone for their help but it appears this can go no further.
I think the only way forward is either to leave it as it is or get a Hive or similar system to replace the programmer ,thermostat and relay.
I will ring the people who service the boiler and see what they can...
'you presumably did that with the Potterton Programmer CH switch set to ON?'......Yes
'I understand that the way you use your CH is that in the morning you get up, and switch the slider on the programmer from the OFF to the ON and then when you are satisfied with the temperature, you then slide...
It was 'proving normal operation of the thermostat' but as far as I recall I did not see the flame symbol come on. In fact I have not seen that since this started.
I telephoned Honeywell and proved in their eyes that the BDR91 and the DT92 were both working correctly . I went into loft with the thermostat and followed directions. The green light on the relay box went off and then on, at the right times. This proved to Honeywell that there was not a...
Thank you very much again for both your replies. We are going out this morning so I will digest what you have said and reply in more detail later on today.
My OH is happy what we have at the moment and has asked me to ensure that boiler keeps working at all costs!
We moved here a couple of...
Thank you for your reply.
We have always thought the flame symbol showed the thermostat was communicating with the boiler. The fact that we have not seen it at all since this started was very confusing.
'So in normal operation, when the temperature is at 13 degrees first thing in the morning...
Many thanks for this and the other replies above.
To answer your question above re the green light on all the time......yes it is!
The reason I have been holding of about re binding is not just because of the inaccessibility but if it goes wrong it could lose us our heating until it is fixed...
A friend has just recommended a Hive or Tado system which would cost around £100 to buy and an Electricians time to install.
If this was a solution to my problem I would certainly consider it. I would be very grateful for any comments.
Thank you for your reply.
I thought the problem that I have would be an easy fix. The set up with the thermostat, relay box and programmer has worked faultlessly for over 1 year. Just for the last couple of days, the connection symbol on the thermostat has not shown which has resulted in an...
Thank you very much for the replies.
Could someone advise the cheapest way out of this problem. We only use the Potterton Programmer to switch the water and central heating on and off. I realise the temperature is controlled by the DT92 and therefore the BDR91 is needed. I do not intend to do...
I have been through your post and the green light is showing on the BDR91 all the time. I looked at it before I put the heating on this morning and it was green. When I put the heating on it was still green and when I switched it off it was still green (as photo 1 attached). Photo 2 shows the...
