Not fully HVAC related, but found this set up at a site for their breaker panel. all the lights in the building are push buttons and use holding circuits and these contractors for their on and off function (I'm assuming). also is used for the majority of their fuses and breakers for the building. had to find the drain line heat trace fuse. of course was the very last fuse in the panel.... I believe the tablet is suppose to be an interface to monitor blown fuses ect, but it was not functioning.. anyone ever seen a system like this before?
