3.2.2 CO

SETPOINT
The ventilation system operates in one of the following modes. In each of these modes, the control device adjusts the
ventilation system to a configured ventilation level.
The device measures the level of CO
2
in the air continuously and compares the measured value to a configured setpoint.
The device controls the ventilation accordingly to keep the measured level of CO
2
below the requested level. When it is in
Comfort mode, the requested level is the same as the configured value. In Eco mode, the requested level is 250 ppm above
the configured value.
The control device drives the fan according to the highest values sent by the linked wireless sensors. When you start the timer
mode from this device, the ventilation will be active for 30 minutes.
ABSENCE MODE:
It represents periods of non-occupancy
, when the heat recovery unit will operate at the lowest capacity.
MAXIMUM TIMER:
High fan speed, for a limited time.
When the button is pressed, the heat recovery unit will reach maxi-
mum speed for 30 minutes.
ECO MODE:
Sensor-based automatic ventilation. In ECO, the system will begin at a higher CO
2
level to ventilate like
in
COMFORT mode.
COMFORT MODE:
Sensor-based automatic ventilation. The system will accelerate the CO
2
-based ventilation after a certain
default activation value is exceeded.
AT HOME MODE:
It represents occupancy of the home or a room.
By selecting this button, the heat recovery system
knows that there is one person (or more) in the room or home. It will set the speed to the default level.
NOTE
The device stores the fan speed values configured on the control device and requests them from there. The device
stores the CO
2
setpoint itself and does not communicate it to any other device.
