[Equest-users] script language to change lighting schedule

[Byron Burns]

I always have to refer back to the help files within eQUEST to get it figured out.  The excerpt below is from Volume 3: Topics > Building Description Language > Keyword Expressions

Thanks Byron,

Can you explain what these command mean: #L("A"), #SI("A","B","C") ? Thanks!

Try this, you will need to change the name of the schedules and c-activity-desc.

   LIGHTING-SCHEDUL = (
{if(#L("ZONE-TYPE")== #SI("CONDITIONED","SPACE","ZONE-TYPE")) then
               switch(#L("C-ACTIVITY-DESC"))
               case "off1": #SI("off1 - office open InsLt Sch","SPACE","LIGHTING-SCHEDUL")
               case "off3": #SI("off3 - 24 hour InsLt Sch","SPACE"," LIGHTING-SCHEDUL ")
               case "caf1": #SI("Cafeteria Light","SPACE"," LIGHTING-SCHEDUL ")
    case "dat1": #SI("Mech/Elec/Com Light","SPACE"," LIGHTING-SCHEDUL ")
               case "mec1": #SI("Mech/Elec/Com Light","SPACE"," LIGHTING-SCHEDUL ")
               case "war1": #SI("off1 - office open InsLt Sch","SPACE"," LIGHTING-SCHEDUL ")
               case "bay1": #SI("off1 - office open InsLt Sch","SPACE"," LIGHTING-SCHEDUL ")
               case "dumm": unused
               default: #SI("off1 - office open InsLt Sch","SPACE"," LIGHTING-SCHEDUL ")
                              endswitch
               else
                              unused
               endif
               } )

Subject: [Equest-users] script language to change lighting schedule

Hi,

I'd like to know how to define lighting schedule using "user-defined default expression"? For instance, I'd like to change lighting schedule for all apartments to "LT_APT", what's the exact script I should use? I've tried something like:
Switch(#L("C-ACTIVITY-DESC"))
Case "APT": "LIGHTING-SCHEDUL"="LT_APT"
Endswitch

But I'm sure there are some errors in my script, especially the underlined portion...Thanks!
