Nick,
Yes, you can edit the exterior lighting fractional schedule with the
photocell keywords. You need to add this in the .inp -- it is not
currently in the eQUEST interface.
"Ext ltg sch" = SCHEDULE-PD
TYPE = FRACTION
PHOTOCELL-CTRL = DAY-OFF
MONTH = ( 12 )
DAY = ( 31 )
WEEK-SCHEDULES = ( "ext ltg wk sch" )
..
Just tried it and it works great.
