AUXILIARY CONTROL
The electronic control has an auxiliary output which can
control external devices in a water treatment system.
The signal is 24V DC, current draw 500 mA maximum.
The Auxiliary Output terminals are located on the elec-
tronic control board (See Schematic on Page 31).
For more details on the use of auxiliary controlled
equipment in water treatment systems, consult the
EcoWater Systems “Problem Water Guide.”
