Using Pump Start/Master Valve and Well Recovery Controls
The following examples are provided to help illustrate various methods of using automatic Pump Start/Master Valve
(PS/MV) and Well Recovery timing controls and how they relate to station operation throughout a watering program.
Example 1: The irrigation supply is pumped directly from a well.
Program setup:
• Program start time: 3:00 a.m.
• Assigned Stations: 1, 2 and 3 each with a 20-minute station run time.
• PS/MV circuit: On.
• PS/MV circuit delay: 60 seconds.
• Well Recovery time: 0 seconds (default).
• PS/MV circuit operation during well recovery: Disabled.
Example 2: The TMC-212 controls the well water pump which feeds a holding tank. The irrigation supply is gravity
fed from the holding tank.
Program setup:
• Program start time: 3:00 a.m.
• Assigned Stations: 1, 2 and 3 each with a 20-minute station run time.
• PS/MV circuit: On.
• PS/MV circuit delay: 2 seconds.
• Well Recovery time: 15 minutes.
• PS/MV circuit operation during well recovery: Enabled.
