Starter on how to set up, reset and master the AEVA digital timer box for your lights.
There are 2 parts to the AEVA digital light timer box - the timer and the dimmer.
The dimmer can be turned far left to the lowest light level and far right to the highest light level.
Now let's start setting up the timer!
Always set to turn on the lights for either 18 hours for non-flowering plants or 12 hours for flowering plants.
Before starting the timer make sure that:
1. The 2 wires on the timer are linked to the lights
2. The timer is plugged into the outlet
3. Make sure that the dimmer is pointing the far right

Check if the screen displays a backwards 6 (∂) on the left side. Press the C/R button 4 times to unlock so that you can use the other buttons again.
2) Lights not turning on
There are a few cases why the lights are not turning on. Here is a solution for it.
First, use a pen to press the C button - this resets the timer. Then, do the steps 3-8 from the procedures.
3) No power to the timer
It is time to replace the timer box. Check our article: Replacing Lights and Timer Box in the AEVA

When setting the timer, you most likely moved the manual button to OFF then AUTO. A quick solution is resetting the timer again.
