American Aldes DHV-150H Manuel D’Utilisation

The DHV-150H can be equipped with various 
accessories to enhance its operation. A remote control 
panel must be used with the DHV-150H. There are two 
remote control panels from which to choose. The 
humidity/fan control panel is used to control humidity 
and the fan. The ventilation timer and humidity control 
panel is used to control ventilation, humidity and the 
fan. 
 

 
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. 
 

 
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 DHV-150H 
unit (and refrigerant-based dehumidifiers in general) 
will reduce a warm space's RH to a lower level than 
that of a cool space. It is therefore pointless to set the 
humidity control to excessively low levels in cool 
rooms; doing so will result in long periods of ineffective 
dehumidifier run time. 
 
Quality humidity meters are available from the factory 
and are recommended to accurately monitor humidity 
levels. 
 

 

 
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. 
 

 

 
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.
