Frequently Asked Questions - 205SF Irritrol
How do I set the start time and duration for each zone?
Press the Program button, select the zone, then use the arrow keys to adjust start time and run time. Confirm with Enter.
What does the rain delay feature do?
Rain delay pauses all watering for a set period (up to 72 hours) to avoid overwatering. Enable it via the Rain Delay button.
How can I manually run a zone?
Turn the dial to Manual, select the zone, set run time, and press Start. The system will water only that zone.
Why is my controller not turning on?
Check the power supply and transformer connection. Ensure the circuit breaker is on. If using a battery backup, replace the coin cell if dead.
How do I connect a rain sensor?
Remove the jumper on the SEN terminals and connect the rain sensor wires. The controller will automatically suspend watering when rain is detected.
Can I set different schedules for different days?
Yes, use the Days setting to choose specific days (e.g., Monday, Wednesday, Friday) or cyclic intervals (e.g., every 3 days).
How do I replace the battery?
Open the faceplate, locate the CR2032 battery holder, remove the old battery, and insert a new one with the positive side up. Close the faceplate.
What should I do if a zone does not water?
Check the zone wiring at the controller and valve solenoid. Ensure the valve is not clogged. Try running the zone manually; if still no water, the solenoid may need replacement.
How do I clean the controller?
Turn off power. Wipe the exterior with a damp cloth. Do not use abrasive cleaners. For the interior, use compressed air to remove dust.
Can I use this controller with a pump?
Yes, the 205SF supports pump start relay (PSR). Connect the PSR to the P/MV terminals. Refer to the manual for wiring details.
