Room humidity setpoint and band may be changed.
The band is the proportional band from the set
point. In this example, the system will operate at
49%RH and reach full output at 40%RH.
Type is Proportional or Propor Integral.
Time is the integral time during which output is
increased to achieve setpoint.
2
Supply humidity high limit setpoint may be changed.
The band is the proportional band from the setpoint.
In this example, the system will begin modulating
down at 80%RH and will be off at 90%RH.
3
The point at which the atomizing stages come
on and off within the proportional band may be
changed.
For this example, stage 1 will activate at 10% of the
proportional band or about 49%RH, shutting off at
50%RH. Stage 2 would activate at 46.5%RH and shut
off at 47.5%RH.
4
Stages 3 and 4 on and off points may be changed.

This screen displays only if the outside air reset
temperature sensor is installed and activated.
As the outside air temperature drops below Setpoint,
the Room Humidity Setpoint is automatically reduced
by the Hum Set Drop value to avoid condensation.
