Does Anyone know anything about honeywell vav commercial zoning controls. I have 17 reheat vav boxs with zone sensors in each zone. My question is what software do I need to set the zone temps and what do I need to hook my computer to the ebus or zone sensor. I have tried to contact honeywell tech support and can't get any help there. I believe the controls are called excel 10. I have also tried to google that and can't find anything that helps out there either.
