PROGRAMMING INSTRUCTIONS

CHANGING FROM HOT TANK THERMOSTAT TO THERMISTOR CONTROL

All

WL2FW Water Treatment Systems

come from the factory programmed for a Hot Tank

Thermostat. Currently the WL2FW Hot Tank uses a Thermostat. The option to change to a

Thermistor Control is for a future Hot Tank design.

Do not change to Thermistor or it will disable

the Hot Tank.

Unplug Power Cord and remove Top Cover to access Heater Control PCB.

Pin Numbers

Heater Control PCB – P/N EN-6131 – WLCP PN 20-0075

Thermostat Heater Control is the default.

PCB Jumper JP9 in the "ON" position (Pin 1 and 2)

Thermistor Heater Control

The option to change to a Thermistor Control is for a

future Hot Tank design.

Do not change to Thermistor, it will disable the Hot

Tank.
