- Initial Settings: Upon first power-up, you may need to set the system time and preferred temperature units (Fahrenheit or Celsius) via the menu.
Operating Instructions
Navigate the controller's menu using the 'Up', 'Down', 'Enter', and 'Back' buttons. The 'Quick-key' button allows for quick viewing of the output level.
Setting Output Mode and Level
- From the main screen, press 'Enter' to access the menu.
- Navigate to 'Output Mode' and press 'Enter'. Select 'Auto', 'On', or 'Off'. 'Auto' mode allows the controller to manage lights based on programmed cycles and temperature settings.
- Navigate to 'Output Level' and press 'Enter'. Adjust the desired light output percentage or wattage using the 'Up' and 'Down' buttons. The EL1 can control output up to 115% (e.g., 1150W for a 1000W fixture).
Configuring Light Cycle
- In the menu, select 'Light Cycle'.
- Set the 'On' and 'Off' times for your lighting cycle.
Setting Temperature Levels (Auto-Dim/Shutdown)
- From the menu, select 'Set Temp Levels'.
- You can set different temperature thresholds for 'Night' and 'Day'. If the room temperature exceeds these set points, the controller will automatically dim the lights to reduce heat or shut them off to prevent damage.
Sunrise/Sunset Ramp Settings
- In the menu, select 'Sunrise/Sunset'.
- Adjust 'Ramp Up' and 'Ramp Down' times. This feature allows the lights to gradually increase or decrease in intensity over a set period (e.g., 20 minutes), simulating natural sunrise and sunset conditions.
Viewing Logs
