3.3.1.3.1Configurable digital inputs
A custom airflow settings for supply and extract fans can be set and assigned to a digital input. Each fan can have a dif-
ferent 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.
3.3.1.4 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.
AFIREPLACE function has the highest priority between user functions. Other functions activated via HMI/APP can in-
terrupt 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.
Fig. 2 Hierarchy of user modes and digital inputs
Modes are listed from the highest to lowest priority; A — user modes that can be activated from the control panel; B —
user modes and functions activated via digital input

3.3.2 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.
3.3.2.1 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 heat-
er during cold nighttime.
If the temperature is very low and the heater is activated during the nighttime (even with lowered temperature set-
point), then during the upcoming daytime indoor temperature will be increased using the heat exchanger so that accu-
mulated 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: ECO mode is always activated by the following modes:
• Auto
• Manual
• Away
• Holiday
• Central Vacuum Cleaner Function
• Cooker Hood Function
• Fireplace
• Away
• Holiday
ECO mode is always deactivated by the following user
functions/modes:
• Crowded
• Refresh
• Free cooling
3.3.3 Airflow settings
Airflow settings are available only in MANUAL mode. Click on fan icon on the main screen to enter SET
