No heating because of BDR91?

[Dan Robinson]

he offered to replace for a HIVE system, i said fine, but when he opened up the BDR he said it was too badly wired for him to attach HIVE instead.

He's obviously an idiot. It's only 3 or 4 wires.

From your description replacing the Honeywell receiver with hive will not sort your problem. The BG bloke just seems to be making excuses!

Is there a way to test this prior to shelling out money for another underfloor inspection of some kind?

is there a standard wiring set up for a BDR91 which would connect hot water and heating?

What happens if you press the button on the BDR91?

Does the programmer also control hot water times, or are there two channels for two heating zones?

Which programmer do you have, is it a Sundial RF2?

so here's the inside of the bdr

and the other piece

 

[Echo the husky]

It's not showing!

 

[Newtothisstuff]

how about now?

 

[Echo the husky]

That's better! There appears nothing drastically wrong there.

 

[D_Hailsham]

Do you have a multimeter and know how to use it?

 

[Newtothisstuff]

i don't and unfortunately not either

have i been blagged?

 

[Newtothisstuff]

sorry and to reply to D_Hailsham

it controls two different heat zones, and is controlled by a ST95OOC

i have tested the thermostat pairing to see if when i turn the relay off the thermostat turns it back on, which it does

 

[Dan Robinson]

As I suspected, the British gas guy is a muppet.


Can you confirm the definition of "tripping" I'm wondering where the blue wire from terminal B goes?

 

[Newtothisstuff]

sorry repeating his terminology. in the context he said it, it referred to the relay blocking the CH from coming on even after it had received a signal to do so

 

[Echo the husky]

Ah, that's different then! Have you attempted to reset and re-pair? Have you done a signal level check?

 

[Dan Robinson]

He's talking booloocks though.
