HUMIDITY CONTROL
If a humidity probe is connected to the controller, the Expert-32P offers
two mechanisms for controlling humidity. The humidity level can be
decreased by increasing the fans’ running time (or the fan speed) within
the minimum ventilation cycles. If the humidity level is too high, the mist
units (fan stages with timer-based relays and the mist cooling stages)
can be stopped to avoid increasing the humidity level any further.
1
Viewing Relative Humidity
Set the function to
RELATIVE
HUMIDITY
using the menu select
buttons. The relative humidity is
displayed.
Press the down-arrow key.
Today's minimum humidity reading
is displayed, along with the time
and date.
Press the down-arrow key. Today's maximum humidity reading is
displayed, along with the time and date.
Keep pressing the down-arrow key to display minimum and maxi-
mum humidity readings for the previous six days. Use the up-arrow
key to return to the previous display screens.
2
Adjusting Minimum Ventilation Compensation
The minimum ventilation fans' running time increases as the humidity
level increases. The additional fans’ on time is totally added when the
humidity level exceeds the RH set point by 10%. The fans' running time
can be increased by an amount ranging from 0 minutes, 0 seconds to 30
minutes, 59 seconds.
Set the function to
HUMIDITY
COMPENSATION
using the menu
select buttons. The humidity level
above which the compensation
starts (RH Set point) is displayed,
as well as the on time increment.
