[QUOTE="M17BMD, post: 522543, member: 34480"] 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 an air duct coming at the bottom to deliver fresh cool air and and inline fan and duct at the top of the unit to circulate the fresh air through the cupboard space. The fan should normally be in the off position but only comes on for 5 minutes after the doors have been closed. I would like that when the door is opened, the interior light comes on and when placed back in the closed position the light is turned off and a signal is sent to the inline fan to turn it on. The inline fan has an overrun timer built in so I assume that as long as a signal was sent to the fan and the fan had a live feed that this would allow it to start up and then turn off automatically rather than the switch sending the live feed? I would ideally like one type of door contact switch to make this all work but wonder if this would be possible? Any help would be greatly appreciated. Thanks, Brian [/QUOTE]
