• Flow Rate – Start From: Select whether the flow rate calculation in an irrigation will begin either with the
value Zero (which means that the flow rate will increase according to pulses received), or a Nominal value
calculated using all the active valves in the irrigation. The calculation method is important primarily for dosing
and EC/pH control. When using a controller which operates with relatively slow pulses, it is recommended to
choose the Nominal flow rate option due to inaccurate flow calculation in the first stage of the irrigation. When
operating with slow pulses and starting with a Zero value, it will take a long time for the controller to reach its'
actual flow rate value. When operating by fast pulses, choose either Zero or Nominal.
• Calculated Flow Delay: This parameter is relevant only when Nominal is being selected in the previous
parameter. This parameter defines the time the controller uses its' nominal flow rate value before switching to
the calculated one. In this period LOW FLOW and HIGH FLOW alarms will not be detected.
10.3 Temperature Calibration
This menu enables calibrating temperature sensors. Use the Left/right arrow keys to increase/decrease the values.
Netafim recommends calibrating the temperature sensors using a reference sensor.
10.4 Humidity Calibration
This menu enables calibrating humidity sensors. Use the Left/right arrow keys to increase/decrease the values
Netafim recommends calibrating the humidity sensors using a reference sensor.
