[Equest-users] Exterior lighting Sch

This is a question I can nail down pretty well actually.

When the photocell control feature first became available in eQuest, I plunged into trying it out and ran into the same snafu you're finding with the help file entry.  The entry is written in a way you'd think you have to use ON/OFF, but that isn't the case.  You can opt to use multiplier and still use the photocell-ctrl input (fractional might work - can't say I've tried).

Attached is a discussion paralleling your query made by myself a few years back with some examples.

I'm pretty sure you'll find MULTIPLER to work for you.  Here is an example of a multiplier w/ photocell schedule in action:

Here is what I end up doing sometimes. Look in the drop down list where you want to allocate the parking schedule to see which existing schedules show up as a choice. Then look at one of these schedules to see the type - that is the type that you need. If multiplier is not working and this is for lighting - you might try fraction.

Hi Nick,

Thank you very much for all of your help.
To create a schedule for parking lot I used the following that I found in DOE-2 help. That looked perfect to me, but as you explained it to me I have to used the sch type multiplier.
Do you have any suggestion how to get it right?

Thanks again

PHOTOCELL-CTRL
Accepts a code-word specifying whether the hourly value in the referenced DAY-SCHEDULE can be overridden either ON (value = 1.0) or OFF ( value = 0.0) according to whether it is day or night.
DAY-OFF                     Forces the hourly schedule value to be 0.0 whenever the sun is up.
DAY-ON                       Forces the hourly schedule value to be 1.0 whenever the sun is up.
NIGHT-OFF                  Forces the hourly schedule value to be 0.0 whenver the sun is down.
NIGHT-ON                   Forces the hourly schedule value to be 1.0 whenever the sun is down.
For example, assume lighting in a parking lot is to be on from dusk until 11 p.m. The earliest the lights are allowed to illuminate is 4 p.m., but will not actually start until the sun is down:
"Parking Lot DSch" = DAY-SCHEDULE-PD
TYPE               = ON/OFF
VALUES             = ( 0., 0., 0., 0., 0., 0.,
                       0., 0., 0., 0., 0., 0.,
                       0., 0., 0., 1., 1., 1.,
                       1., 1., 1., 1., 1., 0. )
"Parking Lot WSch" = WEEK-SCHEDULE-PD
TYPE               = ON/OFF
DAY-SCHEDULES      = ("Parking Lot DSch")
..
"Parking Lot Sch" = SCHEDULE-PD
TYPE               = ON/OFF
PHOTOCELL-CTRL     = DAY-OFF
MONTH              = (12)
DAY                = (31)
WEEK-SCHEDULES     = ("Parking Lot WSch")

Hi Arash,

If your custom schedules are created and appear in the component tree on the left, and the schedule names are not appearing in the appropriate dropdown menu, odds are your custom schedules are either the wrong schedule type (TYPE = MULTIPLIER in this case) or the full day/week/annual schedules are not set up completely.

If the first suggestion should be the issue, I advise always right-clicking the corresponding input field to review any pertinent help file entries before embarking on any custom scheduling efforts.

Subject: [Equest-users] Exterior lighting Sch

Hi All,

I added my exterior lighting power densities directly at direct loads under electric meter, and I created Parking Lot Sch, Parking Lot WSch, Parking Lot DSch.

My question is how can I connect the Sch to Exterior loads, because right now under Schedule I do not have this Parking Lot Sch.

Thanks in advance for your help
