The Santa Fe UltraMD33 has an illuminated display, user selectable setpoint, and a power ON / OFF button located behind the diffuser. The diffuser is fastened with tamper resistant screws to limit access to the control. The diffuser can also be fastened with the included phillips screws if limiting access to the control is not needed. When turning power on for the first time, the set point will be at the factory setting of 55% RH. In the event of a power outage, the dehumidifier restarts at the previous set point when power is restored. Pressing the middle button (the power button), the control will toggle the Santa Fe UltraMD33 to turn ON or OFF. If the unit is on and power button is pressed, control will turn compressor and fan off. As a result, both DISPLAY and LED will go off. If the unit is off and power button is pressed, control will turn fan on. As a result, both DISPLAY and LED will go on.
