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.

Zone 1

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:

ignore the Dim At setting and ONLY use the Stop At setting. .

Stop at:

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:

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:

the light cycle.

SENSOR "ASSIGN":

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:

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.
