7.4 Zone Setting Page(s)
Each of the 4 zones within the DLM-4 Zone Controller has a separate
page for that zone’s particular settings. The settings are described
below.
Wattage:
Select the wattage of ballast that will be connected to this
zone. (Each zone can only have one type of ballast connected) Choose
between 1000, 600 and 315 watts.
Output Max:
Select the wattage that you would like to operate the
fixtures in increments of 25 watts. The user can select any setting
between 600 watts and 1150 watts for the 1000 watt fixture. For the
600/750 fixture any setting between 400 watts and 825watts can
be selected. (The 315 watt fixture is pre-set at 315 watts) Each zone
can operate the fixtures connected to it at different power settings.
When the lights are running normally (without dimming) this setting
determines the wattage each zone will operate at.
*NOTE:
The DLI 315 watt fixtures
CANNOT
be dimmed.
On at:
This is the time of day that the lights for that zone will be turned
ON.
Off at:
This is the time of day that the lights for that zone will be turned
OFF.
Dim at:
The user can select the temperature that they want the
lights within each zone to dim. Dimming the lights will reduce the
heat-load within the growing area and lower the temperature within
the growing area. The DLM-4 Zone Controller provides a gradual
dimming from full power, down to approximately 60% power as the
temperature rises above the user’s “Dim At” setpoint. (Dimming occurs
over a 5’F differential from the Dim At setpoint)
*NOTE:
The 315 watt ballast cannot be dimmed. The 315 watt lights will
ignore the Dim At setting and
ONLY
use the Stop At setting. .
Stop at:
The user can select the “maximum” temperature that the
growing area can get to before shutting down the lighting zones. This
setting should normally be set at least 5’F up to 10 degrees F above the
“Dim at” setting. If the temperature continues to rise in the growing
area, the lights connected to each zone can be shut off to eliminate
overheating of the growing area.
Sun R/S time:
The DLM-4 Zone Controller can simulate Sunrise and
Sunset. By slowly raising and lowering the lighting level (brightness)
Sunrise and Sunset can be simulated. The user can select whether
they want to use this feature or not by setting the Sun R/S time.
The user can select up to 30 minutes in 5-minute increments for
the Sunrise / Sunset feature. When the lights are turned on by the
timeclock, the lights will gradually brighten to simulate morning, and
when the lights are scheduled to turn off, they will dim to simulate
the setting Sun.
*NOTE:
Using this function will
NOT
add additional Lights ON time to
the light cycle.
SENSOR “ASSIGN”:
Each of the temperature sensors can be assigned
to separate control zones, or to multiple zones. Some users may want
to assign each sensor to separate zones, others will want to use a
single sensor to control multiple zones. Having the ability to assign
the temperature sensors to each zone allows much greater flexibility.
The user can select which temperature sensor will be assigned to each
zone within this setting.
*NOTE:
It is recommended that each zone has a separate temperature
sensor for best / most accurate temperature measurements in large
areas.
The Zone setup allows the user to select how to display the ballast
watts of power as well as to “assign” a specific temperature sensor
to each zone. Below shows another example of how the Zone page
might look.
The user will set each individual zone up within the Zone pages. Once
all of the Zones are set-up, the unit is ready for operation.
