Description
Cooling recovery
Automatic cooling recovery is active when extract air temperature from
apartment is lower than outdoor air temperature and there is a cooling demand
(temperature setpoint is lower than outdoor air temperature).
No cooling recovery with heating demand. If the outdoor air temperature is
higher than then thee indoor air temperature and there is a heating demand,
function Free heating is activated instead.
Free cooling
Function decreases indoor air temperature by using only cool outdoor air during
nighttime to save energy consumption.
Moisture transfer
Function controls the rotation speed of the heat exchanger to prevent moisture
transfer to supply air due to high relative humidity in the extract air.
Function is only available for units with Rotating type heat exchanger.
Defrosting
Function prevents formation of the ice on the heat exchanger during cold
outdoor temperatures.
Secondary air
Warm air from the living space is used to defrost the heat exchanger using a
damper inside the outdoor air duct. The unit switches from outdoor air to
secondary air while the extract air fan stops and warm secondary air increases
the temperature inside the heat exchanger.
Vacuum cleaner
Function sets speed of supply air fan to High level and extract air fan to Low
level to increase air pressure within the apartment for better dust collection
through central vacuum cleaner.
Function can be activated via digital input — Central Vacuum Cleaner
Function.
Always active while digital input is activated.
Cooker hood
Sets speed of both supply and extract air fans to Maximum level to increase
airflow in the cooker hood.
Function can be activated via digital input — Cooker Hood Function.
