HUMIDITY CONTROL
If a humidity probe is being used, the Expert-50 has three mechanisms
for controlling humidity. When the relative humidity is too high, the
minimum ventilation speed can be adjusted by a fixed amount. Secondly,
the mist units are shut off whenever the relative humidity exceeds a
user-defined maximum value (this applies to those relays configured in
cooling timer mode for fan stages 2 to 15). Finally, the heater outputs
can be activated in timer mode whenever the relative humidity exceeds
a user-defined level. All these mechanisms must be enabled separately in
the user setup.
Viewing Relative Humidity
Set the function to
RELATIVE HUMIDITY
using the menu select
buttons. The relative humidity is displayed.
Press the down-arrow key. The
minimum humidity value for the
current day is displayed, along
with the time and date.
Press the down-arrow key once
again. The maximum humidity
value for the current day is
displayed, along with the time and
date.
Keep pressing the down-arrow key to display the minimum and
maximum humidity values for the previous six days. Use the up-
arrow key to return to the previous display screens.
Humidity Compensation
The stage 1 minimum speed can be adjusted automatically as a function
of relative humidity. As humidity increases, the stage 1 minimum speed
increases proportionally to compensate for the change. At humidity
levels at or below the humidity set point, stage 1 minimum speed is equal
to the normal uncompensated speed. The user specifies the percentage
increase in minimum speed for a relative humidity equal to the humidity
set point + 10%. For example, if the minimum speed is 40% and the
Humidity 75%RH
