My electrician has said that to get one PIR to control everything then I would possibly need a PIR sensor with a Common, NO & NC connectors with the NO being connected to the LED light strip and the NC side being connected through the relay and then onto the fan to control when the fan comes on...

Thanks for your response, but will the one sensor allow the light to come on when motion is detected (i.e. when doors are opened) and then a pulse signal to be sent to the relay to engage the fan at a later stage (i.e when the doors have been closed again) or would you just set a time delay on...

Hi, I just wanted to come back on and let you know that the Techna timer relay works well and has solved this problem for me so once again many thanks for your help. I was able to pair this up with a 'push to make' and a 'push to break' door switches which allow the fan and the LED light strip...

That's great, thank you. I have spoken to Techna about this timer relay and they believe that it should be the correct relay for this application so I have now ordered one and it should arrive later this week so I will let you know how I get on. Once again, many thanks to both of you for your...

I have a set of double doors leading into this space and both would have to be opened to access the cupboard as they are quite narrow doors so I could work a switch on each door. The problem I have with the fan coming on when the doors are open is that it kind of defeats the purpose because it...

Thanks for coming back to me. The 2 switches make sense to me as I have a set of double doors into the space and I could mount a fridge switch on each door, However I'm not just quite making sense of the switch for the fan as I would only need to be sending a quick signal to the fan to engage...

Thank you both for your feedback. Do you think then that a limit switch to control the 2 circuits (1NO + 1NC) would work in this situation or would you be better with a separate fridge type switch to compete each of the functions? Thanks

Thanks for your reply. Yes but I want the fan to be normally in the off position and it would only come on when the door is closed and then runs for the 5 minutes on the overrun timer to cool the space back down again. I need to get a switch or motion sensor to complete both functions - Turn...

Hi, I am new to this and just currently 2nd fixing a new build house at the moment. I have a small pantry in a new house which has been designed with insulated walls and doors, etc. with the idea being that it is kept at a different temperature to the rest of the house to store food. There is...
