Hunter X-Core Owners Manual And Programming Instructions page 159

Operation enabled, and set to YES, more ET FUNCTION
options will be available and viewed in the ET FUNCTIONS
home screen.
NO will hide all ET functions and the daily ET will not
be read or displayed, and no ET will be available for the
central computer.
Other ET functions will not be available if ET Operation is
not set to YES. Enabling ET Operation is mandatory if you
choose to utilize the ET Sensors for irrigation shutdown. If
ET Operation is not programmed to YES, then the location
of ET Rain, ET Temp, and ET Wind will not be available
in the Extended Features of Set Sensor Operation, as a
selection in mapping sensor locations.
et SenSOr CheCK
Turn the dial to Advanced Features and arrow down to ET
FUNCTIONS. Press the + button. Arrow down to ET
SENSOR CHECK, and press the + button to check the
sensor, after the ET Sensor is connected. The controller
will request an update from the sensor, and if a response
is received, will indicate OK. If the test fails (ET Sensor
does not respond), check wiring to sensor, and try again.
Note ET sensor connection is polarized (green terminal on
the ACC master module must be connected to the green
terminal on the ET Sensor, black terminal must connect to
black terminal).
VIeW et SenSOrS
Displays current readings from all individual sensors on
the ET sensor platform. Turn the dial to Advanced Features
and arrow down to ET FUNCTIONS. Press the + button.
Arrow down to VIEW ET SENSORS, and press the + button.
The display will show current readings from all individual
sensors on the ET sensor platform.

ET, Rainfall, Wind speed, and Temperature will be
displayed according to the Units of Measure setting at the
Set Current Date/Time dial position.
Readings can be updated at any time, by performing a new
ET Sensor Check first.
Solar: always displayed in Watts/m2, based on hourly average.
Temp: air temperature taken near top of each hour, displayed in
Fahrenheit or Celcius.
Humidity: air humidity taken near top of each hour.
Wind: hourly average, in kilometers or miles per hour. If
optional ET Wind is installed this will show actual wind at the
location. Otherwise this value is set by the Automatic Prevailing
Wind factor setting on the underside of the ET Sensor.
Rain-New: Rainfall in inches or millimeters since the last time
the computer uploaded ET data.
Rain-1Hr: Rainfall in inches or millimeters within the last hour.
The controller checks the sensor every 15 minutes, and two
clicks of the rain gauge 0.02" (0.51 mm) within any 4 readings
will create a rain alarm (if the ET Rain is configured as a Sensor
input).
et AlArM SetuP
Individual ET sensors can be used to perform alarm
shutdowns, by assigning them to the Sen 1-4 positions in
the controller. The ET Sensors will then function exactly
like "Clik" Sensor inputs. They may have Suspend or
Pause responses set by Program.
Assigning ACC Sensor 1-4 alarm functions to an ET
Sensor is done without connecting any additional wires.
The controller will use the sensor data as a virtual alarm.
For ET Alarm setup, you will need to assign or "map"
the ET sensors to the Sen 1-4 inputs, at the Set Sensor
Operation dial position "extended features". The ET
Alarm setup function sets the shutdown levels for these
sensors, but they will not be effective until the mapping is
completed.
Press and hold the Information button, turn the dial to Set
Sensor Operation, and release the Information button.
Arrow down to Location selections. If ET is enabled,
there will be three possible selections to map to sensor
locations: ET Rain, ET Temp, and ET Wind. Select and
assign to specific sensor numbers as desired.
