PHOTOCELL-CTRL problem

4 posts / 0 new
Last post

I'm at the point of troubleshooting the application of PHOTOCELL-CTRL to
my exterior lighting loads.

My lighting loads are accounted under an electrical meter as shown on
the attached image.

The help file and previous discussions on this mailing list seem to
indicate that the use of PHOTOCELL-CTRL requires that the referenced
schedule be of the type "ON/OFF."

The conflict is that a schedule applied to an exterior direct load under
an electrical meter must be of the type "MULTIPLIER." If I set up my
schedules as "ON/OFF" per the PHOTOCELL-CTRL directions, they don't
appear in the dropdown list to be selected in the attached screengrab.

I want to apply PHOTOCELL-CTRL behavior for my exterior light
schedules... can anyone point me in the right direction to make this
happen? Is it possible PHOTOCELL-CTRL just works when the schedule is
of the type "MULTIPLIER?"

Attached is the the DOE2 help file entry in its entirety for reference.

Also for reference, my 3 Exterior Lighting Schedules look like this at
the moment:

----------DAY

"ExtLtg Dusk/Dawn DaySch" = DAY-SCHEDULE-PD

TYPE = ON/OFF

VALUES = ( 1, 1, 1, 1, 1, 1,

1, 1, 1, 1, 1, 1,

1, 1, 1, 1, 1, 1,

1, 1, 1, 1, 1, 1 )

..

"ExtLtg Dusk/12AM DaySch" = DAY-SCHEDULE-PD

TYPE = ON/OFF

VALUES = ( 0, 0, 0, 0, 0, 0,

0, 0, 1, 1, 1, 1,

1, 1, 1, 1, 1, 1,

1, 1, 1, 1, 1, 1 )

..

"ExtLtg Security DaySch" = DAY-SCHEDULE-PD

TYPE = ON/OFF

VALUES = ( 0, 0, 0, 0, 0, 0,

0, 0, 0, 0, 0, 0,

1, 0, 0, 0, 0, 0,

0, 0, 0, 0, 0, 0, )

..

----------WEEK

"ExtLtg Dusk/Dawn WeekSch" = WEEK-SCHEDULE-PD

TYPE = ON/OFF

DAY-SCHEDULES = ( "ExtLtg Dusk/Dawn DaySch" )

..

"ExtLtg Dusk/12AM WeekSch" = WEEK-SCHEDULE-PD

TYPE = ON/OFF

DAY-SCHEDULES = ( "ExtLtg Dusk/12AM DaySch" )

..

"ExtLtg Security WeekSch" = WEEK-SCHEDULE-PD

TYPE = ON/OFF

DAY-SCHEDULES = ( "ExtLtg Security DaySch" )

..

----------ANNUAL

"ExtLtg Dusk/Dawn AnnSch" = SCHEDULE-PD

TYPE = ON/OFF

PHOTOCELL-CTRL = DAY-OFF

MONTH = ( 12 )

DAY = ( 31 )

WEEK-SCHEDULES = ( "ExtLtg Dusk/Dawn WeekSch" )

..

"ExtLtg Dusk/12AM AnnSch" = SCHEDULE-PD

TYPE = ON/OFF

PHOTOCELL-CTRL = DAY-OFF

MONTH = ( 12 )

DAY = ( 31 )

WEEK-SCHEDULES = ( "ExtLtg Dusk/12AM WeekSch" )

..

"ExtLtg Security AnnSch" = SCHEDULE-PD

TYPE = ON/OFF

MONTH = ( 12 )

DAY = ( 31 )

WEEK-SCHEDULES = ( "ExtLtg Security WeekSch" )

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.

Thanks Brian!

I simultaneously figured out that PHOTOCELL-CTRL is in fact compatible
with MULTIPLIER type schedules. The root of my problem was that using
ON/OFF as with the help file's example meant I couldn't select that
schedule to apply to my external direct load within my "exterior
lighting" electrical meter (at least within eQuest).

In the spirit of avoiding misinformation in the archive, here are my
corrected schedules for anyone else that is facing this in the future:

----------DAY

"ExtLtg Dusk/Dawn DaySch" = DAY-SCHEDULE-PD
TYPE = MULTIPLIER
VALUES = ( 1, 1, 1, 1, 1, 1,
1, 1, 1, 1, 1, 1,
1, 1, 1, 1, 1, 1,
1, 1, 1, 1, 1, 1 )
..
"ExtLtg Dusk/12AM DaySch" = DAY-SCHEDULE-PD
TYPE = MULTIPLIER
VALUES = ( 0, 0, 0, 0, 0, 0,
0, 0, 1, 1, 1, 1,
1, 1, 1, 1, 1, 1,
1, 1, 1, 1, 1, 1 )
..
"ExtLtg Security DaySch" = DAY-SCHEDULE-PD
TYPE = MULTIPLIER
VALUES = ( 0, 0, 0, 0, 0, 0,
0, 0, 0, 0, 0, 0,
1, 0, 0, 0, 0, 0,
0, 0, 0, 0, 0, 0 )
..

----------WEEK

"ExtLtg Dusk/Dawn WeekSch" = WEEK-SCHEDULE-PD
TYPE = MULTIPLIER
DAY-SCHEDULES = ( "ExtLtg Dusk/Dawn DaySch" )
..
"ExtLtg Dusk/12AM WeekSch" = WEEK-SCHEDULE-PD
TYPE = MULTIPLIER
DAY-SCHEDULES = ( "ExtLtg Dusk/12AM DaySch" )
..
"ExtLtg Security WeekSch" = WEEK-SCHEDULE-PD
TYPE = MULTIPLIER
DAY-SCHEDULES = ( "ExtLtg Security DaySch" )
..

----------ANNUAL

"ExtLtg Dusk/Dawn AnnSch" = SCHEDULE-PD
TYPE = MULTIPLIER
PHOTOCELL-CTRL = DAY-OFF
MONTH = ( 12 )
DAY = ( 31 )
WEEK-SCHEDULES = ( "ExtLtg Dusk/Dawn WeekSch" )
..
"ExtLtg Dusk/12AM AnnSch" = SCHEDULE-PD
TYPE = MULTIPLIER
PHOTOCELL-CTRL = DAY-OFF
MONTH = ( 12 )
DAY = ( 31 )
WEEK-SCHEDULES = ( "ExtLtg Dusk/12AM WeekSch" )
..
"ExtLtg Security AnnSch" = SCHEDULE-PD
TYPE = MULTIPLIER
MONTH = ( 12 )
DAY = ( 31 )
WEEK-SCHEDULES = ( "ExtLtg Security WeekSch" )
..

Yes -- that is exactly my understanding. That would simulate solely
photocell control.

The only time you would not do that is if there was some other override
also controlling the lighting.
