Danfoss 103 to Drayton LP111 for Potterton Boiler

by **dyce1984** » Thu Jun 15, 2017 4:41 pm

currently trying to swap the danfoss for the drayton and its not happening
the boiler is a potterton combi and there is a thermostat in the hallway I've tried to interpret the drayton instructions using the corresponding terminals for the danfoss ...
there is a 4 core coming from the boiler live/neutral and black connected to the stat then to term 2 of the drayton also a blue connected to the stat and then to terminal 6 of the drayton

what I have at the moment is the stat controlling the boiler at all times and the drayton seemingly not involved at all ...

Line in Danfoss 6 Drayton L
Neutral Danfoss 5 Drayton N

The Line may be linked Danfoss 3 Drayton 1 or you could have volt free connection.
To boiler Danfoss 1 Drayton 3

I would guess there is a link wire and you have missed moving that across.
