4.5.1.3.1Configurable digital inputs
Description
A custom airflow settings for supply and extract fans can be set and assigned to a digital input. Each fan can have a different airflow setting.
Configurable digital input can be activated via signal triggered by push button, presence detector or any other external
device with digital output, such as Building Management Systems (BMS)
Configurable digital inputs are grouped in levels of priority, Configurable Digital Input 1 being the highest,
meaning it can’t be overwritten by other user functions.
4.5.1.4 Digital input and Mode hierarchy
User modes and functions have a different hierarchy. User functions activated via HMI or mobile APP, such as AWAY,
CROWDED, FIREPLACE, HOLIDAY and REFRESH, are interrupted by manual selection of AUTO and MANUAL fan modes.
A FIREPLACE function has the highest priority between user functions. Other functions activated via HMI/APP can interrupt each other.
If FIREPLACE function is hard-wired on the connection board and configured as digital input (DI) then it has a higher
priority than AUTO and MANUAL mode. Digital input for a FIREPLACE function has also a higher priority than other
hard-wired digital inputs (DI) for: AWAY, CENTRAL VACUUM CLEANER, COOKER HOOD, CROWDED, HOLIDAY or REFRESH.

4.5.2 Temperature settings
Temperature can be set at SET TEMPERATURE menu accessible from the home screen by touching
TEMPERATURE icon with thermometer. Default temperature value is 18°C (range 12–30°C).
Use up and down arrows or a slider to change the value.
Then touch the OK button to confirm changes.
Temperature set point is for room air temperature, supply air temperature or for extract air temperature depending on
which control mode is active. Default setting is Supply air temperature control.
Control mode of the temperature can be changed in Service menu.
4.5.2.1 ECO mode
ECO mode is a power saving function that can be activated in SET TEMPERATURE menu.
ECO mode function is available only when an internal heater is installed and configured.
While ECO mode is active, a temperature setpoint at which heater is activated is lowered to avoid activation of the heater during cold nighttime.
| 01_1.8.0
Configuration |
If the temperature is very low and the heater is activated during the nighttime (even with lowered temperature setpoint), then during the upcoming daytime indoor temperature will be increased using the heat exchanger so that accumulated heat could be used during the next cold nighttime, the lowered setpoint for the heater remains.

ECO mode will have impact for the following user
functions/modes if selected:
• AUTO mode
• MANUAL mode
• AWAY mode
• HOLIDAY mode
• CENTRAL VACUUM CLEANER function
• COOKER HOOD function
• FIREPLACE mode
ECO mode is always activated by the following modes:
• AWAY mode
• HOLIDAY mode
ECO mode is always deactivated by the following user
functions/modes:
• CROWDED mode
• REFRESH mode
• FREE COOLING function
4.5.3 Airflow settings
Airflow settings are available only in MANUAL mode. Click on fan icon on the main screen to enter SET
AIRFLOW menu.
Use up and down arrows or a slider to change the airflow value.
The airflow may be adjusted in these steps: Off/Low/Normal/High. These settings control output signals to the supply and extract fans.
Important
It is not recommended to set fan to Off in standard households. If manual fan stop is activated, the unit
should be provided with dampers in exhaust and fresh air ducts to avoid cold draught and risk of
condensation when the unit has been stopped.
The fan can be set to Off by activating Manual Fan Stop function in Service menu.
4.5.4 Indoor Air Quality
The unit automatically controls indoor humidity and/or CO2levels by adjusting airflow setting. Airflow is
increased if air quality is decreasing.
Demand Control function is responsible for IAQ (Indoor Air Quality) regulation. Relative humidity (RH) and/or CO
sors are responsible for IAQ monitoring.
Indoor air quality (IAQ) indicator is available if AUTO mode and Demand Control function is activated.
IAQ levels:
• ECONOMIC: Actual IAQ value is below low IAQ set point.
• GOOD: Actual IAQ value is between low and high IAQ limits.
• IMPROVING: Actual IAQ value is above high IAQ set point.
Different airflow settings can be set for IMPROVING and GOOD IAQ levels in Service menu.

Function decreases indoor air temperature by using only cool outdoor air during
nighttime to save energy consumption.
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.
Function prevents formation of the ice on the heat exchanger during cold
outdoor temperatures.
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.
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.
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.
