@desibrainp Builder advised you? The irrigator that installed the system is required by law in Texas to walk through the system with you and explain everything, not the builder. Including a watering schedule. I advise you to contact the licensed irrigator that installed the system and request a walk through. There should be a sticker on the controller you removed or some info near the controller. You should also have an irrigation design showing you a layout, including your drip around the foundation.
Here’s a link to the state code that irrigators are to follow: Completion of Irrigation System Installation
