3 Operation
The
3.1 Humidity/Fan Control Panel
See Figure 7: 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. This panel should be mounted in a central area of the structure where it can accurately sense the humidity of the air in the living space. The panel has a cover that must remain open to the air within the living space for accurate humidity sensing.
The humidity/fan control panel can be used in conjunction with the optional fresh air damper. When used with the optional fresh air damper, the fan/filter switch will act as a fresh air ventilation control. When the switch is ON (in this configuration), the fan will run, the fresh air damper will open, and fresh air will be filtered and brought into the structure. When the switch is OFF, the fresh air damper will close and the fan will operate only when the humidity control calls for dehumidification. Contact the factory for instructions on this type of installation.
3.2Ventilation Timer and Humidity Control Panel
See Figure 7: The ventilation timer and humidity control panel automatically controls both the ventilation and the humidity of the living space. The ventilation timer and humidity control panel contains an adjustable humidity control, a fan switch, and a ventilation timer. This panel will control the humidity and allow programmed ventilation of the living space. This panel works in conjunction with the optional fresh air damper to provide ventilation.
This panel should be mounted in a central area of the structure where it can accurately sense the humidity of the air in the living space. The panel has a cover that must remain open to the air within the living space for accurate humidity sensing.
3.3 Humidity Control Adjustment
Set the humidity control to the desired humidity level for the home. 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 unit's dehumidification rate; the unit will simply run longer to reduce the area's RH to the setting. The
Quality humidity meters are available from the factory and are recommended to accurately monitor humidity levels.
3.4 Fan/Filter Switch
Turning ON the fan/filter switch will cause the central conditioning unit's internal fan to run continuously, whether the central conditioning unit is dehumidifying or not. This function is desirable if the central conditioning unit is used for air circulation and filtration to achieve maximum indoor air quality. When the switch is ON; air will be constantly filtered through the central conditioning unit and circulated throughout the house. When the switch is OFF the fan will operate only when the humidity control calls for dehumidification or when the ventilation timer calls for ventilation.
3.5 Ventilation Timer
The ventilation timer controls the fan and the motorized fresh air damper. When the ventilation timer is activated, the central conditioning unit 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.
In cold climates or areas where the outdoor dew point is low at times, ventilation can be used to dehumidify the structure. This approach is often more economical than running the dehumidifier to remove excess moisture from the structure. For example, in a house that experiences condensation on the interior surface of the windows during the winter, increasing the amount of ventilation will often cure the problem.
