Irrigation Programming - Soil Moisture Irrigation
This is another smart on-demanding watering equipment type. This mode is used in conjunction with a moisture sensor.
It allows you to define a dryness level in the root system of the plants. Once this dryness level is reached, the Pearl will deliver water for a specified amount of time.
This should increase the moisture level of the roots and the cycle starts again. There are built-in deadband to prevent repeated watering around the same moisture reading.
To measure the volumetric water content of the soil, to use soil moisture irrigation, you would need a Pearl 5 input module and a soil moisture sensor to achieve this task.
The first screen is where you set the valve OnTime (length of On Time) once the threshold is triggered. These next two entries on the screen are where you set the time window during which you will allow the irrigation valve to be triggered. If the threshold is reached outside this time window, the irrigation will be triggered at the start of the time window.
Both the start and stop times can be fixed times by selecting the at option or they can be based on Sunrise and Sunset. The Maximum Off Time is a safety feature. If no trigger has occurred after the Max Off Time, then the valve will come on either immediately or at the start of the next time window. As with all irrigation equipment types, you can optionally assign a supply pump ID to activate the associate supply pump for this particular channel.

Irrigation Programming - Accumulated Light Irrigation
In this mode the irrigation cycle is triggered when the accumulated light or “light sum” reaches a threshold or when the maximum off time limit is reached. This mode gives the system the ability to water on a demand based usage to match the plants ...Irrigation Programming - Vapor Pressure Deficit (VPD) Accumulation Irrigation
Another advanced on-demand irrigation equipment type for the Pearl is the Vapor Pressure Deficit (VPD) accumulation mode. VPD is the difference (referred to as deficit) between the amount of moisture in the air and how much moisture the air can hold ...Irrigation Programming - Irrigation Cycle
This mode is often used for plant propagation or with misting. In this equipment type, the irrigation valve is cycled continuously during the time window that you have selected. The cycling option is for turning a valve on and off at some repetition ...Irrigation Programming - Scheduled Irrigation
Scheduled Irrigation mode is like a time clock where you set the start time, run time and days of the week. Scheduled mode allows the Pearl™ to turn the Irrigation channel on for a duration equal to OnTime at up to six start times per day. Use N:A to ...Pearl Control System Manual - V1.18.2 (May 2026)
