Humidity Control - Komfovent C5.1 Manuel D'installation Et D'utilisation

EN
The OVR function provides for three operation modes selectable depending on the needs of the user:
1. The mode "When on" – the function will respond to the external control contact only when the air handling
unit is on.
2. The mode "When off" – the function will respond to the external control contact only when the air handling
unit is off.
3. The mode "Always" – the function will respond to the external control contact irrespective of the operating
condition of the unit.
The OVR function has the top priority and, therefore, ignores all previ-
ous modes. The function remains active as long as the external control
contact is in the closed position.

2.5.2.7. Humidity control

Humidity control function is designed for maintenance of air humidity determined
by the user. For proper operation of the function one or two additional humid-
ity sensors shall be connected, depending on where humidity will be maintained.
There are two modes for maintenance of humidity:
• Supply air. The determined humidity of supply air is maintained, using the
supply air duct humidity sensor (B9).
• Room air. The determined humidity of indoor air is maintained, using the room
air or exhaust air duct humidity sensor (B8). The supply air humidity limit is set
using the duct humidity sensor or hydrostat (B9).
One of the below methods can be chosen for maintenance of the determined
humidity:
• Humidification of air. There is a control signal of 0...10 V, directly reflecting
the capacity of the humidifier from 0 to 100 %. If humidification is required, the control is transferred through
the output TG3 of the controller.
• Dehumidification of air. There is a control signal of 0...10 V, directly reflecting the capacity of the dehu-
midifier from 0 to 100 %. If dehumidification is required, the control is transferred through the output TG3
of the controller.
• Dehumidification of air: cooling-heating. Dehumidification is performed using the coolers and heaters
available in the air handling unit. If there are several coolers and heaters, then it shall be pre-determined
which of them will be used in the dehumidification process.
• Humidification and dehumidification of air. For humidification of air the control signal of 0...10 V is used
through the output TG3 of the controller, and the dehumidification of air is performed using the coolers and
heaters available in the unit.
If the maintenance of the room air humidity is provided for, then the hu-
midity function will prevail over the air quality and recirculation functions,
i.e. when humidification or dehumidification is required, these functions
will be blocked.
Humidity control function must be ordered in advance.
