Understanding Programs
A program is a complete watering schedule: which zones run, what days, when they start. Most controllers have multiple programs (A, B, C).
Why multiple programs matter:
- Program A:Front and back lawn zones, Mon/Wed/Sat
- Program B:Drip zones for beds, Tue/Fri
Each program operates independently.
Setting Start Times
The start time is when the program begins, not when each zone runs.
If your start time is 5:00 AM with four 20-minute zones:
- 1Zone 1: 5:00–5:20 AM
- 2Zone 2: 5:20–5:40 AM
- 3Zone 3: 5:40–6:00 AM
- 4Zone 4: 6:00–6:20 AM
You only need one start time per program.
Best practice for DFW: Start early enough to finish before sunrise (4:00–6:00 AM).
Setting Runtimes (Zone Duration)
Runtime depends on:
- Sprinkler type (rotors need 30-45 min; sprays need 10-20 min)
- Soil type (clay absorbs slowly)
- Sun exposure
- Slope
| Zone Type | Runtime | Notes |
|---|---|---|
| Rotors (turf) | 25–40 min | Split if runoff occurs |
| Spray heads | 12–20 min | Watch for pooling |
| Drip (beds) | 30–60 min | Deep, infrequent |
Starting points for DFW clay soil
Cycle and Soak
Run a zone for 10 minutes, pause 30 minutes, then run another 10 minutes. Valuable for clay soil and slopes.
This technique prevents runoff and allows water to penetrate deeper into clay soil.
Seasonal Adjustment
Adjust your controller's seasonal percentage to account for changing weather:
Spring
70–80%
Summer peak
100–120%
Fall
60–70%
Winter
0–30%
When to Call a Pro
If your controller won't hold programming, displays errors, or controls zones erratically, it may need replacement.
Common signs you need professional help:
- •Controller resets programming after power outages
- •Display shows errors or won't turn on
- •Zones run at wrong times or won't turn off
- •You want to upgrade to a smart controller
Proper controller programming leads to healthier, more water-efficient lawns
