    Question

    Does anyone know of a way to add a time delay after a loss of power?? I have UNT and DX controllers on site. Does this have to be done thru the NC?? I want to be able to stage the units back ON, or if the generator is still running, keep some OFF.

    Thanks

    You'd need an input from the gen. and then either direct map to the controllers or write a GPL stradegy to accomplish this.

    UNT Each output (or FCU/HEAT Pump/AHU/ etc) has a delay or start on delay - you could Increse..thru HVAC pro! on these systems.

    Also the DX you can program Hold outputs, start delays and even use a input from a gen status is on thru a plc block /etc to help you out! (thru gx9100..you can set the Pamm, to default Hold, low etc)

    And/or.... I agree (with chrisc, Professional Member)use GPL to do this..If it a whole bldg, campus /etc)
