Function

TEMPERATURE PROFILE2

To set the settings of the temperature profile.

SET MODE2

�

  ADAPTIVE: The desired indoor temperature to which the unit will adjust the heat recovery control 

varies with the outdoor climate (adaptive comfort technology). The set temperature can be 
increased or decreased with 1,5°C from the average setting by selecting the WARM or COOL 
temperature profile; (default setting)

�

  FIXED: The desired indoor temperature to which the unit will adjust the heat recovery control is 

fixed and does not depend on the outdoor climate. The set temperatures can be changed in FIXED 
PRESETS for each temperature profile.

FIXED PRESETS2

�

  WARM: set the temperature for the temperature profile mode WARM in FIXED mode; (Default = 24°C 

or 76°F)

�

  NORMAL: set the temperature for the temperature profile mode NORMAL in FIXED mode; (Default = 

20°C or 68°F)

�

  COOL: set the temperature for the temperature profile mode COOL in FIXED mode. (Default = 18°C 

or 64°F)

UNITS2

To change the displayed units of the temperature and airflow rate.

TEMPERATURE2

�

  CELSIUS: the unit will display the temperature in degrees Celsius; (default setting)

�

  FAHRENHEIT: the unit will display the temperature in degrees Fahrenheit.

FLOW2

�

  m³/h: the unit will display the airflow rate in cubic meters per hour; 

�

  l/s: the unit will display the airflow rate in liters per second. (default setting)

SEASON DETECTION2

To set the season detection for heat recovery control.

HEATING SEASON2

Prevent the unit from counteracting the effect of the (central) heating system.  

�

  HEATING LIMIT RMOT4: set the heating-limit5 RMOT4 (Default: 11°C);

�

  STARTS NOW: start the heating season and save the current RMOT4 as the heating-limit5. 

COOLING SEASON2

Prevent the unit from counteracting the effect of the (central) cooling system. 

�

  COOLING LIMIT RMOT4: set the cooling-limit6 RMOT4 (Default: 20°C);

�

  STARTS NOW: start the cooling season and save the current RMOT4 as the cooling-limit6. 

RF SETTINGS2,7

To set the settings of the RF sensor(s).

RF SENSOR PRIORITY2,7

�

  ON: the unit will translate the signal from an RF sensor to an airflow signal in the AUTO mode and 

MANUAL mode; (default setting)

�

  AUTO ONLY: the unit will only translate the signal from an RF sensor to an airflow signal in the AUTO 

mode;

�

  OFF: the unit will ignore the signal from an RF sensor.

RF SENSOR FUNCTION2,7

�

  FLOW PROPORTIONAL: the unit will translate the signal from an RF sensor to a corresponding 

airflow between the minimal and maximal set airflow. (default setting)

�

  FLOW PRESET: the unit will translate the signal from an RF sensor to one of the preset airflows.

INSTALLER DEFAULT2

�

  RESET: All software values mentioned in this document will be returned to the default settings.

2 This menu is only visible when the advanced mode is active.

4 RMOT = running mean outdoor temperature (average temperature over past 5 days).

5 heating-limit = the temperature below which the (central) heating system is normally active. 

6 cooling-limit = the temperature above which the (central) cooling system is normally active.

7 This menu is only visible when the unit has RF functionality.

3.3 Use during disasters

If a disaster calls for you to close all doors and 
windows you must also stop the unit. You can do this 
in one of the following ways:

�

  Switch off the power supply of the outlet to which 

the unit is connected;

�

  Switch off the power supply group at the fuse box 

to which the unit is connected;

�

  Pull out the power supply cable from the outlet to 

which the unit is connected.
