DESCRIPTION
INTENDED USE
The device is designed for the following purposes:
- To set the ventilation level via the fan speed, according to the user input or the measured level of CO2.
- Configure the parameters for controlling the ventilation. Any other use or additional use is not in compliance with the intended use.
OPERATING PRINCIPLE
The device communicates with the control device via wireless communications for controlling the ventilation. Via the button and the LEDs, you can read and configure the control mode that the ventilation system is currently in. When it is in Eco mode or Comfort mode, the device requests the ventilation level according to the amount of CO2 in the air.
VENTILATION SPEEDS AND MODES
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.
ABSENCE MODE:
It represents periods of non-occupancy, when the heat recovery unit will operate at the lowest capacity.
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.
MAXIMUM TIMER:
High fan speed, for a limited time. When the button is pressed, the heat recovery unit will reach maximum speed for 30 minutes.
ECO MODE:
Sensor-based automatic ventilation. In ECO, the system will begin at a higher CO2 level to ventilate like in COMFORT mode.
COMFORT MODE:
Sensor-based automatic ventilation. The system will accelerate the CO2-based ventilation after a certain default activation value is exceeded.
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.
CO2 SETPOINT
The device measures the level of CO2 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 CO2 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.
NOTE: The device stores the fan speed values configured on the control device and requests them from there. The device stores the CO2 setpoint itself and does not communicate it to any other device.
