Hi all

I've just been asked to fit a Honeywell DT92E to a Potterton Promax 30 FSB. It has a BP2000 programmer and Honeywell centre. It does not have a user thermostat fitted hence the DT92E. I have racked my brains staring at the Honeywell Manual hoping for some lightbulb to go off in my head. Unfortunatley I just get a dull throb.

I know there is another thread regarding the dt92e and I have read and re-read for some help but it seems to be a one for one swap(ish). Can any one please let me know how to wire it in and with what (four core etc). The installation leaflet has confused the pants off me with four different set ups. And whats the purpose of the two lives on the incoming?? and link??

Please help

Thanks in advance

permenant live and neutral to it from either the fused spur or junction box ignore the second live connection on unit.

CH outlet from clock currently goes to a terminal in junction box then onto motorised valve , break this by taking it from clock to A on unit and out of B on unit to motorised valve
