4.6E Digital Controller WITH Fresh Air AND Damper
4.6F Digital Controller WITHOUT Fresh Air
4.1A Humidity/Fan Control Panel WITHOUT Fresh Air Ventilation or Damper
The humidity/fan control panel automatically controls the humidity of the living space. The humidity/fan control panel contains an adjustable humidity control and a fan switch. The panel has a cover that must remain open to the air within the living space for accurate humidity sensing. When the fan switch is in the “ON” position, air will be continually filtered and circulated throughout the home. For humidity control operation refer to section 4.2.
4.1B Humidity/Fan Control Panel WITH Fresh Air Ventilation and WITHOUT Damper
The humidity/fan control panel automatically controls the humidity of the living space. The humidity/fan control panel contains an adjustable humidity control and a fan switch. The panel has a cover that must remain open to the air within the living space for accurate humidity sensing. Outside air is continually introduced whenever fan is “ON.” Manual operation of fan filter switch controls outside air ventilation. Since the fan operates whenever the Ultra- Aire XT150H is dehumidifying outside air will also be introduced. For humidity control operation refer to section 4.2.
4.1C Humidity/Fan Control Panel WITH Fresh Air Ventilation AND Damper
In this configuration, a motorized damper has been installed in the fresh air duct. When the fan/filter switch is in the “OFF” position, the damper is closed. The
When the fan/filter switch is in the “ON” position, the motorized damper will open and the fan will run, introducing outside air. The unit may or may not be dehumidifying in the ventilation mode, depending on the humidity control setting. See Section 4.2 for humidity control operation.
4.1D Ventilation Timer and Humidity Control WITH Fresh Air AND Motorized Damper
Refer to sections 4.7 through 4.9C.
4.1E DEH 3000 Digital Control WITH Fresh Air AND Damper
Refer to Section 5.
4.1F DEH 3000 Digital Control WITHOUT Fresh Air
Refer to Section 5.
4.2 Humidity Control Adjustment
Set the humidity control to the desired humidity level for the home. Turning the knob clockwise results in a drier setting. See the back
of the control panel cover for set points. The dehumidifier will run continuously until the relative humidity (RH) is reduced to the humidity control dial setting. Setting the humidity control to lower RH levels will NOT increase the dehumidification rate; the unit will simply run longer to reduce the RH to the setting. The
4.3 Fan/Filter Switch
Turning ON the fan/filter switch will cause the

4.4 Ventilation Timer
The ventilation timer controls the fan and the motorized fresh air damper. When the ventilation timer is activated, the Ultra- Aire XT150H will circulate the indoor air, and bring in fresh air from outside. The ventilation timer should be set for the required ventilation of the residence. The home should be ventilated with fresh air as suggested by applicable codes and standards or as required by the homeowner. The ventilation timer is an electronic timer that displays the current time. This timer has battery backup, so it will not require resetting after a power outage. Following
a prolonged power outage the display of the timer will flash on and off indicating a power outage has occurred. The
