# What do the AUX 1 and AUX 2 buttons do on my monitor controls?

## I see buttons marked AUX 1 and AUX 2, they don’t seem to do anything. What are they?

There are two electronic “switches” in the motor control box that can be used to open and close valves, turn on flood lights, or for other needs of the end users by using the YE-REMAUX dual relay box.
