The LEIT Link Remote Control Handset is a 2-way radio communication device that operates in
the ISM band 902-928 MHz (868/869 Europe). The LEIT Link is a practical solution to field
communications and the management of any LEIT XRC controller in remote or hard to reach
sites.
Using the LEIT Link Remote Control Handset one can review status reports, modify program
settings, temporarily interrupt a running program to do a manual run, test a valve or skip to the next
valve mode. The current running program and current valve open information is provided when
activated. In Check Status Mode the handset also can review time, date, budget, sensor activation
(if rain sensor is active), and solenoid integrity. In Uplink History one can review the hourly usage of
each valve for all months and annual usage. Manual Run usage per month is also provided. All of
these features can be accessed from a distance of up to 800 feet line of site.
The handset can request or send information and commands to a particular controller. It will also
receive confirmation for the information sent or requested.
IMPORTANT: The LEIT XRC requires greater energy for radio communication than is used for
operation of the controller alone. In order to retain sufficient energy to maintain valve control,
the radio on the controller will automatically turn off in low light conditions.
The LEIT XRC controller requires daily exposure to light levels at a minimum of 15.000 to 20.000
lux, which is equivalent to daylight around 9 AM-10 AM on a cloudy day. On very cloudy days
the controller requires more time to charge up and operate with the radio. To maximize the
energy available the XRC controller should be installed in an open, un-shaded area.
