10.  RH COMPENSATION

The controller offers different way to compen-
sate for high/low relative humidity (RH) levels 
in the room. All compensation functions are 
explained below. 

Refer to section 4.6 to enable the RH 
compensation functions.

1. High RH Comp. on Fan Speed:

The controller can compensate for high RH 
levels  by  increasing  the  speed  of  variable-
speed fan outputs. When this compensation 
function is used, the controller gradually in-
creases the regular speed of variable fans as 
the inside relative humidity level increases*. 
The graph below shows how it works. 

* If variable fans are off and the ventilation level is 

lower than stage 3, the controller will activate the 

fans and increase their speed the same way.

When the RH level exceeds the set point, the 
controller starts increasing the regular speed 
of variable fan output 1; when the RH level 
is 5% above the RH set point, the variable 
output  continues  increasing  in  speed  and 
the controller starts increasing the speed of 
variable fan output 2. The full compensated 
speed  of  both  variable  outputs  is  reached 
when the relative humidity level is 10% above 
the RH set point.

2. High RH Comp.on the Min Vent. Timer

The controller can compensate for high hu-
midity 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.

3. High RH compensation with Kool-Cel®s & 
mist outputs:

If RH levels are too high,  the controller can 
stop  the  misting  output  and/or  Kool-Cel® 
output.  Theses  outputs  are  disabled  when 
RH  levels  reach  the  respective  RH  shutoff 
limit of each output. 

Low RH compensation with mist outputs:

4. 

To compensate for low RH levels,  the control-
ler can activate the misting output in timer 
mode. The misting output starts when RH lev-
els  decrease below the Low RH Set Point.

5. High RH Comp. with the Heating Outputs: 

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.

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.
