HumAbs
– only humidification based on absolute humidity is performed using a
humidifier.
BothAbs
– system dehumidifies and humidifies as needed based on absolute
humidity.
Setpoint
(
Room
/
Extract
/
Supply
)
– first set of humidity sensors:
Room
,
Extract
– these selections apply cascading humidity control, where the
required supply humidity is calculated based on the difference between the required
and actual humidity.
Supply
– this option involves direct humidity control based on the required and
actual supply humidity.
Supply
(
No
/
Supply
/
Outdoor
/
Both
)
– first set of humidity sensors:
Supply
– supply air humidity sensor for humidity control.
Outdoor
– outdoor air humidity sensor to enable passive dehumidification.
Exhaust
(
No
/
Room
/
Extract
/
Both
)
– second set of humidity sensors:
Room
– room humidity sensor for humidity control.
Extract
– exhaust air humidity sensor for humidity control.
AirQuality
(
No
/DI/
Const
/Regul
)
– one sensor with digital contact output (DI) or two sensors
with 0-10V analog output (
Const
/Regul
) can be selected for air quality measurement.
DI
– air quality measurement is performed by a sensor with a digital output, when
activated, increased constant fresh air ventilation is activated.
Const
– increased constant fresh air ventilation is activated when the required air
quality limit measured by one or two analog sensors is exceeded.
Regul
– continuous controlled fresh air ventilation is implemented by PID control
based on the required air quality value and the actual value measured by one or
two analog sensors.

/
Unit
/
MixFlap
/
Contact
)
– selection of damper control
methods:
Unit
– damper opens based on a signal to start the unit.
MixFlap
– damper will be controlled inversely to the mixing damper. This option is
only relevant if the mixing damper is part of the HVAC unit.
Contact
– damper will be controlled by an external contact.
