Hot Swap-able Station Expansion Modules
Easily expand the zone capability by inserting up to
three, 3 station expansion modules for a maximum of 13
stations. This can be done while the unit is connected
to AC power.
Tool-less Communication Wire Terminal
No tools are required to connect the pair of
communication wires to the controller or the sensor.
There is no polarity required on either the controller or
the sensor connection to provide communication.
LED Light to Validate Sensor Communication
A green LED located in the Sensor communication wire
compartment will blink when power is applied and
continuously illuminate when there is communication
between the controller and the sensor. This prevents
the need of going back to the controller to verify
communication during installation.
Adjustable Sensor Mounting Bracket
Mounting Bracket Arms can be adjusted in fine
increments to assist that the sensor pod is mounted
level in virtually any installation scenario. The arms have
a wire routing mechanism that provides a "strain relief".
Rain Gauge
The rain gauge not only acts as a rain shut-off device,
it also provides rainfall intensity and accumulation
information to the controller in order to prevent over-
irrigation by accounting for "effective" rainfall.
Removable Debris Screen
Prevents leaves and other large debris from getting into
the tipping bucket mechanism and preventing accurate
rainfall measurement. It can be easily removed to clean
debris off the screen surface.
Removable "Tipping" Rain Bucket"
The Tipping Rain Bucket can be easily removed from the
sensor housing to clean out debris that may have made
it past the debris screen into the mechanism.
