Explanation control functions
Example: Time modulating humidity control
Inside Hysteresis the control computer controls humidity during a part of the Repeat time. The control
computer calculates this on/off time as follows:
Setpoint: 80%
Measured RH: 75%
Hysteresis: 10%
Repeat time: 100 sec.
The humidity relay will repeatedly be on for 50 seconds and off for 50 seconds.
HumiTemp = Humidification Temperature
If HumiTemp is used, it will correct the measured average house temperature depending on the setpoint and the
measured relative humidity (RH). If HumiTemp is not used, the ventilation is controlled based on the average
house temperature.
Figure 6: Example HumiTemp
The HumiTemp control can only activate if a humidity setpoint has been set and a humidity sensor is adjusted.
The effect of the HumiTemp correction is controlled by the next settings.
The age factor tells how the HumiTemp ® should adapt in relation to the age of animals. This means there is a
link to the minimum ventilation. EARLY (5%) means that even at young animals the HumiTemp will react
strongly. When this factor is NORMAL(10%) the reaction is a more gradually, and this impact is slowly with the
factor at LATE(20%).
At a lower than desired RH the temperature will run down. The degree of correction is limited (safety reason). This
setting specifies how much the compensation may decrease (related to the average house temperature)
TINY (-0.5°C), SMALL (-1.0°C), average (-1.5°C), LARGE ( -2.0°C) and HUGE (-2.5°C).
With a higher than desired RH the temperature will run up. The degree of correction is limited (safety reason).
This setting specifies how much the compensation may increase (related to the average house temperature)
TINY (1.0°C), SMALL (2.0°C), average (3.0°C), LARGE (4.0°C) and HUGE (5.0°C).
