Hi ,
Just wondering if anyone would be able to help.
I will be starting alterations of a bathroom soon, The client would like an extract fan in zone 1 of room which he wishes to operate via the flow of water running to shower.
At the moment i am planning to install a S.E.L.V fan with the transformer in a space under the bath(only accessible with use of a tool !). I was then planning to use a flow switch with wiring into an adaptable box with din rail, and mounting a relay/contactor in said box to switch the 230v supply to fan transformer when flow switch operates.
does anybody know if there is a better way i,e if there are flow switches which could perhaps take the small load of an extract fan and be connected perhaps inbetween the positive conductor entering the fan enclosure and the actual positive terminal of the fan.
would be gratefull for any help, many thanks
