Hi

I am still using a normal room stat to switch the fan on/off but I re-thought how I connect the stat to the fan.

At first I connected the fan between connections 1-3 these are the connections that you would normally use in a central heating system, it did not work, as I seemed to be chasing the stat up the temperature scale but then thought, using the connections 1-4 would be better as these connections are made as the temperature drop's.

I have got the temperature set to 25o C, and I am waiting for an IEC C13 plug to arrive so that I can take the supply from one of the 230V outlets on the back of the UPS and tidy the installation up.

I think that I will still look for a "silent fan" I am a great believer in "Silence is golden"

Thank you for all the inputs from forum members, all greatly appreciated.

Bill
