Auto Mode Calibration

Video Tutorial: Watch the companion video V42: Auto Mode Calibration for a visual walkthrough.

Overview

Auto mode lets sensors control your light levels automatically. For optimal performance, calibration teaches the system how to maintain comfortable light levels while accounting for daylight. This article covers both auto calibration and manual setting methods.

Why Calibrate?

When daylight enters a space, the photosensor sees ambient light plus fixture light combined. Without calibration, the sensor cannot distinguish between them, leading to incorrect dimming decisions.

Benefits of Calibration

  • Removes ambient light interference
  • Provides precise daylight harvesting
  • Maintains desired light level on work surfaces
  • Maximizes energy savings

Working Light Level

The Working Light Level is the brightness your lights maintain when: - Auto mode is active - Motion is detected - Calibration determines this level

Calibration Methods

Method Description Best For
Auto Calibration Self-learning process with light cycling Standard installations
Manual Setting Direct level configuration Problem situations, night-only setup

Auto Calibration

Auto calibration is the recommended method. The system runs a self-learning process where lights cycle on and off to measure the environment.

Running Auto Calibration

  1. Navigate to More → Auto Calibration.
  2. Select a group to calibrate.
  3. Adjust calibration parameters as desired.
  4. Tap Start.
  5. Lights will cycle on/off 4-8 times.
  6. Do not interfere with lights during this process.
  7. Wait for completion prompt.

What Happens During Calibration

Phase Description
Start Calibration begins
Cycling Lights turn on/off 4-8 times
Measuring Sensors read environment
Learning System calculates baseline
Complete Returns to auto mode

Success and Failure

Outcome Indication
Success Lights return to auto mode, turn on normally
Failure Lights flash rapidly 10 times

Calibration Failure Causes

Cause Solution
Excessive daylight Calibrate at night or low-light
Changing ambient light Ensure stable conditions
Sensor installation issues Check sensor positioning
Sensor blocked Clear obstructions

Manual Setting

Use manual setting when auto calibration fails or isn't practical.

Step-by-Step Instructions

  1. Exclude ambient light by:
  2. Configuring at night, OR
  3. Blocking all sunlight from the space
  4. Navigate to the Lights page.
  5. Long press on a sensor-equipped light.
  6. Adjust brightness and color temperature to desired working level.
  7. Tap the Auto button in lower right.
  8. Confirmation appears that auto mode level is updated.

Critical Requirement

For manual setting, you must exclude ambient light. Otherwise, the sensor reading includes daylight, leading to incorrect auto levels.

Auto vs Manual Comparison

Factor Auto Calibration Manual Setting
Accuracy Higher (self-learning) Depends on light exclusion
Convenience Requires cycling time Quick but needs darkness
Ambient light Accounts automatically Must exclude manually
Best for Standard installations Night-only setup, troubleshooting

Best Practices

Practice Benefit
Test with one fixture first Find optimal parameters
Calibrate similar spaces together Consistent results
Verify after calibration Confirm expected behavior
Recalibrate seasonally Account for changing daylight

Troubleshooting

Issue Cause Solution
Repeated failures Environmental conditions Try manual setting
Incorrect light levels Poor calibration Recalibrate under better conditions
Dimming too much Auto point set too low Increase target level
Not dimming enough Auto point set too high Decrease target level
