  • Valves can be allocated to one of five water meters.
  • An optimal flow can be entered for every valve.
  • A minimum, maximum and pipe break flow rate can be specified for each water meter.
  • Valve times can be set from a minimum of 1 second to 10 hours.
  • Valves can be allocated to an irrigation group.
  • Rainfall can be monitored over 1 to 4 days, irrigation programs can be reduced by 25%, 50%, 75% or 100%.
  • Manually percentage adjust (0% to 250%) .
  • Separate manual percentage adjust for programs and valve groups.
  • Continual cycling of irrigation programs between specified time of day. Delay between cycles can be set from 1 minute to 9 hours.
