Photocell type selection: Skylight (Enables the ‘slope between 2 points’ algorithm)
Control method setup MUST be: Schd and photo
Num of control points: 1
Trip level: 2000fc A middle range setpoint.
Trip Range +/- : The value added to the trip level to turn Sales Lights OFF and allow
them back ON.
Trip level of 2000 fc “plus” 200 trip range will turn lights OFF at 2200 fc.
Trip level of 2000 fc “minus” 200 trip range will allow sales lights back ON
at 1800 fc.

Pre delay: Delay in minutes before the zone can come ON. (Scheduled time)
Post delay: Delay in minutes before the zone can be turned OFF.
Minimum ON time: The time that must elapse once the zone has been turned OFF,
before the zone can be turned OFF again.
Minimum OFF time: The time the zone MUST stay stay OFF before coming back
ON.
The ‘Min Out & Max Out’ fields would are interpreted as follows:
Min Out at:
If the skylight sensor indicated a reading greater than or equal to 1800 footcandles (fc),
the dimmer would be set to 2% . (Mnimum output)
Max out at:
If the skylight sensor indicated a reading at or below 800 fc, the dimmer would be set
to 65 % (Maximum output.)
All readings between these 2 extremes would set the dimmer output per the following:
(‘Min out at’ – sensor)
------------------------- x (‘Max. output’ – ‘Min. output’) + ‘Minimum output’
(‘Min out at’ – ‘Max out at’)
Thus, a sensor reading of 1200 fc would result in a dimmer output of:
(1800 – 1200) 600
----------------- x (65% - 2%) + 2 % = ------ x 63% + 2% = 39.8%
(1800 – 800) 1000

Algorithm interval is the algorithm cycle.
Max rate of change is the percentage of adjustment per second.
With a setting of 1 % for a 1 second algorithm cycle, and a 2% minimum and 65 %
maximum output, the full range can be covered in 63 seconds. (1 percent per second
for 63 steps.)
This schedule turns the zone ON and OFF on a time base. (Setup for 24 hours)

This calculation looks at the feedback signal and if it is ever above 70% will become
true. (The maximum allowed is 65%, and if wiring is disconnected, the signal will go
to 100%.)

History screens:
The history sample below shows an ideal dimming scenario. The skylight sensor rises
at the peak light of the day and the system algorithm responds accordingly. The sales
lights go off at 2000 foot candles and back on at 1800.
This is a zoom view of the above history sample. Notice that the variable output and
the dimmer feedback are tracking right along with each other.
