Monitor mode:
the digital input acts as a monitor for the
DI and has no other function.
ASTRONOMICAL TIME
The Astronomical time function may be setup on any of
the channels. It controls and turns off the enabled light
channel for the daylight period form sunrise to sunset.
The following diagram illustrates the typical application of
this capability.
To setup astronomical time, enter the Latitude and Lon-
gitude parameters for the location being controlled. Also
enter the time offset from GMT (Greenwich Mean Time).
For example, the USA Central Standard time zone is
offset -360 minutes from GMT. Madison, Wisconsin, USA
is at 43° 5 minutes North (+) Latitude and 98° 30 minutes
west (+) Longitude. The GMT Offset range is + 720 Min-
utes. Also click the box if applying daylight savings time to
the astronomical time calculation.
Next, select the channel(s) that should have the astro-
nomical time function and click the Enable box. This is
done in the Schedule section of the page.
Note: For non-North American Daylight Saving time set
the manual DLS (Day Light Saving) time.
CHANNEL OCCUPANT OVERRIDE
This is the number of minutes from 0 to 255 (4 hr, 15 min)
which the controller will bring a system that is Off to On
when its override button is pressed. This time can be dif-
ferent for each channel.
Occupied Override:
Select whether to allow an occupied
override and if so, whether it will be a schedule or chan-
nel override.
HOLIDAY VANISHING
Choose whether to enable the Holiday Vanishing Feature.
If checked, the controller will make the number of days
for a holiday 0 after the holiday is over. This will keep
the holiday from occurring in subsequent years if it is not
reprogrammed.
DIGITAL INPUT DELAY/FILTER
Enable the Digital Input Delay if you want the Digital Input
to be present for 15 seconds before it takes effect. This
can prevent cycling. Note, this delay if selected, will apply
to all eight channels.
POWER DOWN PERIOD
If the controller loses power, it can remember which chan-
nels have been overridden and how much time is remain-
ing in each override period. This is the amount of con-
tinuous power loss time in minutes where the controller
will remember the override status'. If the controller loses
power for longer than this period, the override buttons will
have to be pressed again as necessary.
INPUT VOLTAGE
The input voltage is monitored. The calibration factor is
used to scale the controller's 24 VAC power input to the
appropriate line voltage. For example, if the line voltage
is 120 VAC and the SLQ218 power input is 24 VAC, then
the calibration factor is 5.0. If the line voltage is 120 VAC
and the controller power input is 27 VAC, then the calibra-
tion factor is 4.4 If the line voltage is 277 VAC and the
SLQ218 power input is 24 VAC, then the calibration factor
is 11.5.
DAYLIGHT SAVING TIME
If Daylight saving is used, simply enable the "Daylight
Saving Time" option within the software and enter the
starting month + week and the ending month + week.
