WIRING
All wiring must comply with local codes and ordi-
nances. Make wiring connections according to to dehu-
midifier instructions if available; otherwise, see typical
wiring diagrams in Figs. 5 and 6.
HUMIDITY CONTROLLER ADJUSTMENT
The humidity comfort range of a living space is gener-
ally between 25 and 50 percent RH. However, as the
outdoor temperature changes, the humidity level on the
humidity controller may need to be reset to assure maxi-
mum comfort.
To reduce the relative humidity, reduce the set point ap-
proximately three percent RH every 24 hours. To increase
the relative humidity, increase the set point approximately
three percent RH every 24 hours.
WALL MOUNT HUMIDITY CONTROLLER
Set the humidity set point according to the prevailing
outdoor temperature to provide optimum relative humidity
control for most installations. Adjust the humidity level to
a particular structure using the procedure above.

DUCT MOUNT HUMIDITY CONTROLLER
If the temperature at the humidity controller location
on the return air duct is less than 80 F [27 C] ,use the
procedure for wall mounted humidity controllers.
If the air surrounding the humidity controller is greater
than 80 F [27 C], reset the recommended settings to
compensate for the higher ambient temperature. High ambi-
ent temperatures will cause the humidity controller to control
at an increased setting. To determine the compensated set
point for surface mounted humidity controllers with high
ambient temperatures, use the following procedure:
1. With a bulb type thermometer, accurately determine
the surrounding duct temperature at the humidity controller
location.
2. Decrease the recommended setting about five percent
for each 5 F [3 C] above 80 F [27 C] at the humidity
controller.
For example, if the humidity controller is set at 25 per-
cent and the temperature at the humidity controller is 90 F
[32 C], the compensated set point should be 15 percent.
(This is the 25 percent setting less 10 percent for the 10 F
[6 C] above ambient temperature.)
Place the system in operation and observe through at
least one complete cycle to make certain that all compo-
nents are functioning properly.
