1. Where can I enter design supply temperatures for my heating and cooling plants?
2. How do I enter temperature reset?
3. Where can I enter design supply temperatures for my cooling tower?
4. Do you know how to convert W/gpm (e.g. 22 W/gpm) into a unit compatible with Trace?
2). It depends on which type of temperature reset. Since you are referring to 90.1, I'm assuming hot water, chilled water reset and supply air reset.
3). The temps for the cooling towers are entered under Libraries, equipment, heat rejection. Again, you'll have to copy and save your changes.
4). You must be on an older version of Trace. Trace 6.2.5 has units of w/gpm. Good thing too, as the conversion process is understood well by few.
