EcoWater CHC Series Service And Troubleshooting Manual page 119

The Control Station has been designed to allow the interface to serve many versions of CHC, Filtration,
alert, function and communication options. Most of the options are build directly into the system and
only require connection to the hardware and Setting Screen Configuration to implement their use.
However the optional communication formats require software modification and are not discussed in
this section.
