Thanks Chiu. The expansion product I have mentioned is here. The circuit board within it is exactly the same as the power supply boards in all of the other Comfort boxes that I have.
The web site literature states that it is a 3 amp supply, so I am unclear how it could work with a 1.1 Amp transformer. As you suggest, I have taken this up with the supplier (the same supplier for the replacement transformer as for the original expansion box).
Thanks again,
Nick
