If the left number is larger than the right, then the refill valve will automatically be turned on to fill the tank. The right number is the threshold setting and can be adjusted to compensate for extreme water conditions: very pure, low conductance water requires a higher setting, while high mineral content, high conductance water requires a lower setting. Note that the left number changes from a high value when water is NOT touching the refill probe to a low valve when water IS touching the probe. For best operation, the right number should be set to a value midway between these low and high numbers. Be- fore changing the setting, confirm that the refill probe is free of scale buildup and the connection to it is
