RH Set Point
This is the humidity level above which high
RH compensation functions start. Adjustable
from 20 to 99% of humidity (select “Off”
to disable all high RH comp. functions).
Heater compensation
The timer used by heating outputs is made of an
On Time and of a Cycle Time. Heating outputs run
during the On Time then stop until the end of the
Cycle Time. The On Time portion of this cycle in-
creases as RH levels increase.
Minimum & Maximum On Times
Set the minimum and maximum On Times
of the heating timer. The minimum On Time
starts being used when indoor humidity lev-
els reach the RH set point; the maximum On
Time is used when humidity levels are 10%
above the RH set point.
Accessible if RH compensation with heating out-
puts is enabled in section 4.6.
Cycle Time
Set the cycle time of the heating timer.
Accessible if RH compensation with heating out-
puts is enabled in section 4.6.
Misting outputs on low humidity levels
Accessible if RH comp. on Low RH levels
is enabled in section 4.6.
Low Set Point
Set the humidity level below which misting
units start running in timer mode or select
“Off” to disable this function.
On & Off Times
Set the On and Off Times of the misting timer.
Mist & Cool Cell Shutoff
Set the humidity level above which the misting
output and/or the cool cell output stops or select
“Off” to disable this function.
