3 DESCRIPTION

3.1 INTENDED USE

The device is designed for the following purposes:

1. To set the ventilation level via the fan speed, according to the user input or the measured level of CO2.

2. Conﬁgure the parameters for controlling the ventilation. Any other use or additional use is not in compliance with the

intended use.

3.2 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 CO2in the air.

I 6

DAITSU WIRELESS CO2PROBE / INSTALLATION AND OPERATION MANUAL

3.2.1 VENTILATION SPEEDS AND MODES.

3.2.2 CO2SETPOINT

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 CO2in the air continuously and compares the measured value to a conﬁgured setpoint.

The device controls the ventilation accordingly to keep the measured level of CO2below 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 CO2level 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.

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 CO2setpoint itself and does not communicate it to any other device.
