"Conditions" include CHW temperature, so reset up of CHW if possible maximizes the modeled use of the WSE. <BR><BR>>>> Brian Fountain <bfountain@greensim.com> 7/28/2008 2:12 PM >>><BR>Further to this -- you will likely need to set up your equipment <BR>controls to specify the water economizer chiller type leading in the <BR>winter (below a certain OA) and the regular chillers leading above a <BR>certain OA -- or based on a schedule.<BR><BR>Steve Mignogna wrote:<BR>> You can set up a separate chiller of type "water economizer".
