Using Pump Start/Master Valve and Well Recovery Controls
The following examples illustrate various practical application of automatic Pump Start/Master Valve (PS/MV) and Well Recovery timing controls and how they affect the program watering cycles
Example 1: The irrigation supply is pumped directly from a well.
Program Setup:
•Watering program start time: 3:00 a.m.
•Assigned Stations: 1, 2 and 3 each with a
•PS/MV circuit: On (P On).
•PS/MV circuit delay: 60 seconds (Pd 60).
•Well Recovery time: 0 seconds (S 00).
•PS/MV circuit enabled during well recovery: no (PE n).
Example 2: Well water is pumped into a holding tank where it is gravity fed to the irrigation supply. Program Setup:
•Watering program start time: 3:00 a.m.
•Assigned Stations: 1, 2 and 3 each with a
•PS/MV circuit: On (P On).
•PS/MV circuit delay: 2 seconds (Pd 02).
•Well Recovery time: 15 minutes (M 15). (*See Note below.)
•PS/MV circuit enabled during well recovery: Yes (PE Y). (*See Note below.)
Example 3: The irrigation supply is pumped from a reservoir fed by a
•Watering program start time: 3:00 a.m.
•Assigned Stations: 1, 2 and 3 each with a
•PS/MV circuit: On (P On).
•PS/MV circuit delay: 2 seconds (Pd 02).
•Well Recovery time: 15 minutes (M 15). (*See Note below.)
•PS/MV circuit enabled during well recovery: no (PE n).
*Note: When multiple watering programs are scheduled to operate immediately after one another (i.e., stacked), the Well Recovery time and PS/MV circuit (when enabled), will be operative between consecutive programs.
