v10 Upgrade Kit for Tommy RO
This kit is used to update the Tommy RO unit and controller to the v10 program, which switches from 0.5-3.5v to 4-20ma flow sensors.
This upgrade negates potential ground noise interference from sensors and allows for more consistent readings. This also eliminates the built-in temperature sensor in favor of a mechanical sensor.
Other v10 program enhancements include: a new "run down" mode for better usage of RO water, widened shutdown delay for low pressure fault by 0.5 sec, sol E open at start up for reduced pressure spike, and several other refinements from v9.
