I have a building that is under construction. The engineer has designed a smoke evacuation strategy that requires Carrier economisers to drive full open. I contacted Carrier tech support and they in turn called their engineer who came up with a schematic. This schematic requires closing of a relay that sends 24vac to the 2-10 vdc control input on the damper motor while opening the 2-10 vdc signal. Has anyone seen this done? Will it work without burning up the actuator?
