Notes about special parameters
b1, setting 2: Drain under power
If parameter b1 includes setting 2, the humidifier will continue to produce steam during drain cycles. If this setting
is turned off, the humidifier will open the power contactor during drain cycles.
b1, setting 4: Draining due to a significant reduction in the demand
If parameter b1 includes setting 4, then the humidifier will not drain if the demand for humidification decreases.
This helps to conserve conductivity and is useful in low conductivity waters. If b1, setting 4 is off, then the
humidifier will drain to reduce the output if the demand is reduced by 33%.
b1, setting 8: Automatic draining of the cylinder after period of non-use
If parameter b1 includes setting 8, parameter “bF” may be used to cause the humidifier to empty the steam cylinder
if there has been no demand for humidification for an extended period of time. This helps prevent premature
corrosion of the electrodes and/or contamination of the water in the cylinder. The default setting is for 3 days. The
unit will display “idr” when this drain function occurs.
b1, setting 64: Complete periodic draining
If parameter b1 includes setting 64, then parameter “bE” can be used to set the hours between total drains of the
cylinder. This is useful if the water contains impurities that can cause erratic behavior.
