So I have a normal light switch & fan installation whereby you turn the light on and it also turns the inline extract fan in the loft on for a few minutes on the timer after the light switch has been switched off.
What I want to install is a humidistat that also turns on the fan when humidity is high say 85% and I still want to switch the fan on by the light switch, but I don’t want the humidistat to bring on the light when it is activated which is what would happen if it’s wired in parallel. Any time the SL of the humidistat is linked with the SL of the light switch and fan I’ll get this problem so I need a way around this.
What are my options to get this functionality?
