NOTE: If a Critical Flow alert is triggered, operation of all stations (and master valve)
monitored by the flow sensor will be immediately terminated.
11. Press the button to select Learned Flow (LF). If the Learned flow rate has been previously
established, the PPS value is displayed. If the Learned flow has not been established, the
display will indicate LF -- --.
NOTE: The learned flow rate for each station (assigned to flow monitoring) will be automatically
recorded the first time it is operated.
For PPS/GPM conversion information, see chart on page 28.
12. Press the button. Repeat the flow sensor setup parameters for each station starting at
step 4 on page 17.

Rain Sensor Control Features

Rain Sensor Timed Bypass

Rain sensor input can be manually overridden by placing the sensor control switch in the bypass
position (see item 10, page 4). An alternate method of controlling rain sensor input is by enabling
the Timed Bypass feature. When enabled, Timed Bypass overrides rain sensor input and sensor
bypass switch function, enabling the controller to continue irrigation operations regardless of rain
sensor input.
By default, the Timed Bypass mode is Off until it is enabled. Once enabled, rain sensor input
will be bypassed for the remainder of the day. At midnight, Timed Bypass mode is terminated,
enabling normal rain sensor operations to resume.
