I imagine any mains powered relay (230Vac) would do the job:Cool thanks,
Any suggestions for a suitable enclosure for it? It is the only DIN type device I will have so I am not sure it justifies a case (Unless very cheap!), or whether I can just put it inside a plastic box with a screw-closed front.
MHRV timer - well, I don't think so but I called Vent Axia who said it does, but the advice they gave contradicts the manual!
If I was able to do it that way, can you suggest a suitable device? If it's only a few £ I could try that option first I suppose....
Thanks
Tim
