Humidifier Configuration
The RH is factory configured to operate under most conditions without the need for any changes
to its configuration. If required several settings can be made using jumpers on the RH’s control
board. The output of the RH can also be reduced by using a potentiometer on the RH’s control
board. See Figure 30: RH Control Board Jumpers for location of jumpers and the capacity
adjustment potentiometer.
Note: Nortec recommends not making any configuration changes unless they are required and
that any changes to the RH’s settings be performed by a qualified technician.

Capacity Adjustment
The Capacity adjustment potentiometer can be accessed through the clearance hole in the
cover of the electrical compartment. It can adjust the capacity of the humidifier between 100%
and 30% of its rated output. (Factory setting = 100% output).
Figure 31: Capacity Potentiometer Adjustment
Caution: Never adjust jumpers other than those listed in this section. Other jumpers are
factory set and must not be changed.
