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.
ET Sensor shutdowns only apply to the controller to which
the ET Sensor is connected.
The ACC cannot shutdown other controllers as a result of
these alarms.
ET Sensor shutdowns are not instantaneous, and there
may be a delay of up to 18 minutes between an ET Sensor
alarm and the actual shutdown. If this is not acceptable, a
separate sensor (such as Rain-Clik or Freeze-Clik) should
be installed and wired directly to one of the Sen 1-4 inputs
for instant shutdowns.
The controller will automatically check the ET Sensor for
updated sensor readings every 15 minutes. If an ET sensor
causes a controller Pause or Suspend, that action will
remain in effect for at least 15 minutes until the controller
updates the readings. If the sensor returns to normal the
Suspend or Pause settings will be cancelled, as with any
other sensor.
Note: ET functions will only appear as a Location option
with the updated versions of the facepack firmware (4 or
higher), and an updated ET-ready Master Module. Once
the controller is equipped with these components, ET
must then be enabled in the programming. Turn the Dial
to Advanced Features and select “ET Functions.” Select
“ET Operation,” and press the plus button to confirm
that the controller will “Use ET Sensor.” The ET location
option will then be available to choose as a location for the
controller’s sensors.
When the controller is set to “Use ET Sensor,” more
options are also unlocked within the Advanced Features
“ET Functions” screen. One of these unlocked screens is
labeled “ET Alarm Setup.” Use the Down arrow to move to
the “ET Alarm Setup” screen. Press the plus button, and
you can adjust the shutdown levels for Rain, Temperature,
and Wind.
Rain Max: The maximum amount of rain that will be
permitted before a program is shutdown for the rest of
the day. Move to this position with the arrow keys and
use +/- to set the maximum.
The ET Rain sensor will shutdown programs after 0.02”
(0.51mm) of rainfall within an hour (this amount is not
programmable), but the program may be permitted to run
again if no more rain is detected. The ET Sensor checks for
rainfall every 15 minutes.
If the Rain Max amount is reached, the controller will no
longer attempt to run the program that day.
Temp: The air temperature can be used as a freeze sensor
to stop automatic programs, and the temperature at which
shutdown occurs is programmable (from 25° to 45°
Fahrenheit, -3.8° to 7.2° Celsius). Move to this position
with the arrow keys and use +/- to set the low temperature
shutdown.
Wind: If the optional ET Wind is installed, the wind speed
(in mph or kph) can be used to shut down designated
programs.
Reminder: Alarm settings are not in effect until the
Sensor 1-4 inputs have been assigned to them at the Set
Sensor Operation dial position, and responses have been
configured by program.
