Humidity control
Either Humidification or Dehumidification or both Humidification and Dehumidification.
Timer control
For starting and stopping the unit. Up to 5 timer outputs for control of external functions such as
lighting, doorlocks etc.
Demand control
In buildings with strongly varying occupancy the fan speeds or mixing dampers can be controlled
by the air quality measured by a CO
2
/VOC sensor.
Support control
When using the control function room control or extract air temperature control, it is possible to
utilise support-heating and/or support-cooling. Minimum running time is settable 0…720 minutes.
(factory setting 20 minutes).
Free cooling
The function is used during the summer to cool the building during the night using cool outdoor air
thereby reducing the need to run chillers during the day. The function can also be activated during
the day if the temperature permits it.
Enthalpy control for free cooling/heating
This function is used to override the mixing dampers to increase the recirculation, depending on the
result of the enthalpy calculation.
Cooling recovery
If the extract air is colder than the outdoor air and cooling is required, the heat exchanger control is
reversed in order to return the cool extract air.
Recirculation control
Recirculation of air using a supply air fan and recirculation damper, with or without temperature
control.
Step controllers Heating/Cooling
As an alternative to the analogue control of ”Actuator heating Y1” or ”Actuator cooling Y3” step
controllers can be used for controlling heating or cooling in steps using digital control.
