How to get the Cooling Tower Outdoor Air Inlet Node via EMS

edit

Hello all, I am trying to modify the outdoor air inlet of a coolign tower, but I do not seem to find the variable anywhere. Only the AHU outdoor air inlet is in the OutdoorAir:NodeList. The help file states that "If this field is left blank, the outdoor air conditions entering the cooling tower are taken directly from the weather data", hence the weather data is employed as the outdoor air inlet, but this does not solve my problem because I only want to modify the outdoor air inlet of the coolign tower (and not the weather data). Any suggestion will be greatly appreciated, I am getting very fustrated. Thanks!
