Hey Everyone -

Is there a preferred structure for modeling two-pipe dual-temp systems with a summer winter change over?

For example: Valves, pumps: Should the point be modeled: dual, temp, water, valve, cmd OR chilled, hot, water, water, valve, cmd

The same question would apply for a binary summer/winter change over command.

Thanks, Rob

Robert,

I would consider using a dualTemp tag such as

• dualTemp, water, valve, cmd

on the secondaryLoop if that makes sense for your application.

Robert,

I use heating and cooling instead of summer winter.

Dennis, Thanks for your prompt reply! - I'm just now running into this again and realized I never responded.

Rob

Robert,

How has this been working out for you? I'm working on tagging a similar building where almost all equip is dualTemp but some of the larger AHUs can be heat or cool (steamHeat & chilledWater).
