PROGRAMMING INSTRUCTIONS
DISABLING ENERGY SAVING SLEEP MODE
All WL350 Water Treatment Systems come from the factory with Energy Saving Sleep Mode
engaged to meet the Energy Star Certification requirements. Energy Saving Sleep Mode disables
the heater circuit if the unit has not been used for a continuous 3 hour or longer period.
Selecting any button "wakes up" the WL350 Water Treatment System and turns the heater
circuit back on. The hot tank will typically take less than 10 minutes to heat the water from
ambient to the 85°C (185°F) set point.
Unplug Power Cord and remove Top Cover to access Energy Saver PCB.
WL350 Water Treatment Systems comes with the
Energy Saving Sleep Mode “ON”
PCB Jumper JP7 in the "ON" position (Pin 1 and 2)
Deactivate the Energy Saving Sleep Mode by moving
PCB Jumper JP7 to the "OFF" position (Pins 2 and 3).
