The calculation of the 'Pulse On time' and 'Pause time' is done per each valve per zone, during the
period time. The calculation is done according to the set-point that starts the misting process and
the measured value inside the greenhouse. The values of the 'Pulse On time' and 'Pause time' are
varied between the minimum and the maximum values of the ON/OFF time that were defined per
valve.
• The system gets the start trigger set-point – Temp or Humidity or VPD
• Controller measures the current value of – Temp or Humidity or VPD
• In parallel – calculates the new P factor and I factor
• Calculates the desired capacity
• According to the desired capacity, the system finds the calculated 'Pulse time' and 'Pause time'
as follow. The minimum and maximum pulse and pause time are per valve, per zone.
