I had to replace a pvb yesterday and the customer wanted me to run thru the system. Controller was a src ( boots,s favorite it seams ) manufactur date was dec 1996. Well I figured I would install a smart port and use a remote as I was working alone yesterday.Seeing as I never connected one to an src I took a quick look at the manual to make sure it gets wired the same way as a pro,c ICC . In the manual where it typicaly shows an R for remote it said " reserved for future options" So as I was taking off the old pvb I called hunter teck support and asked if a smart port would work. After asking around the room the teck support guy came back and said " no one knows " Apperently this clock came out before the smart port did. The answer is yes it will work.
