RELATIVE HUMIDITY 12.
(RH) COMPENSATION
The controller can automatically adjust the
value of certain parameters as a function of
the relative humidity (RH) level. This section
explains how each RH compensation function
works and how to program them. The relative humidity compensation func-
tions are only available if the controller
is used in a broiler or turkey facility (in
a breeder facility, the RH sensor is used
to control a humidity output in the egg
room).

the
“On Time”

tilation timer.
12.1. High RH Comp.on the
Min Vent. Timer
The controller can compensate for a high
humidity levels by increasing the level of mini-
mum ventilation. As the RH level rises, the
controller increases the
“On Time” portion of
the minimum ventilation timer to compensate
for the change. The maximum compensated
“On Time” is reached when the RH level is
10% above the RH set point.
Refer to section 5.1 to adjust the RH set point
and refer to the Set-up menu in section 4.4
to enable this RH compensation method (
“Use
RH min vent. compensation” ).

12.2. High RH Compensation
with the Heaters
The controller can compensate for high
humidity levels by activating the heaters in
timer mode. As the RH level increases, the
controller increases the
“On Time” portion
of the heating timer to compensate for the
change. The maximum compensated heating
“On Time” is reached when the RH level is
10% above the RH Set Point.

of the heat
timer
The RH heat timer is composed of an “On
Time” and of a “Cycle Time” . The heaters run
during the “On Time” and then stop until the
end of the “Cycle Time” . The “On Time” por-
tion of this cycle increases as the RH level
increases.
