Error: All valves will not turn on automatically

Possible Solution:

  1. Verify program: station time, watering start times, watering days schedule, current time, current day, water budget and rain delay.
  2. Check valve common wire for proper connection.
  3. Check fuse or breaker if your timer has one.
  4. Ensure rain sensor (if installed) is properly connected and functioning properly. If rain sensor is not installed, ensure the SENSOR SWITCH is in BYPASS position.
