SV3 (Solenoid Valve) Mode/TDS Target
Solenoid valve SV3 is physically connected to the mini-aux board AUX4. When connected to AUX4, the TDS probe is set
up as PRODUCT.
NOTE Unlike SV1 and SV2, which operate at line voltage (220VAC for M2), SV3 must be a 24VAC solenoid
valve such as P/N 01021310.
SV3 has three possible modes of operation: quality flush, permeate flush, and TDS target.
Quality Flush
Solenoid valve SV3 is open whenever the RO system is in Quality Flush mode. This is the default SV3 mode.
Permeate Flush
Solenoid valve SV3 is open whenever the RO system is in Permeate Flush mode.
TDS Target
Target TDS: The RO system keeps track of the average product water TDS whenever the RO system is operating, mixing
lower quality water with product water to meet the average product water TDS. The average TDS measurements of the
RO product water are taken once per second, over an interval specified by the “TDS Target Time.” The controller opens
and closes valve SV3 every few seconds in order to produce product water with a TDS level near the programmed value.
