aerauliqa Quantum NEXT Manual

INTRODUCTION

Quantum NEXT is a single alternate flow decentralized (single point) residential heat recovery unit, also called «push&pull» unit, designed to ensure adequate ventilation in enclosed environments without energy losses.
It is recommended that two units are installed in a pair: when one unit is pulling, the other is pushing.
The pair of units can be installed in the same room or in different rooms (i.e. living-room and bedroom). The unit is suitable for installation on an outside wall.

The unit should operate continuously, and only stopped for maintenance or service.
When heat exchange is not useful (for example in mid-seasons when indoor and outdoor temperatures are similar), or when heat exchange is not recommended (for example with the option "summer free cooling"), it is recommended to set the unit in "extract-only" or "intake-only" mode and NOT to switch it off.

OPERATION

REMOTE CONTROLLER

The unit is supplied with an infrared remote controller (K) as standard, as well as its support base (L) which can be wall mounted. A magnet keeps the controller attached to the base.
The controller is equipped with an LCD display to visualise the setting to be transferred to the unit; anytime a touch button is pressed, the setting shown on the LCD display is transferred to the unit. The IR receiver is placed on the left side of the ventilation unit (E): it is recommended to point the controller towards the receiver when any setting needs to be transfered.
One remote controller can control more units.
To activate the remote controller it is necessary to insert two AAA type batteries (not supplied).

VENTILATION UNIT
When switched on the unit emits a long acoustic signal.
Through the IR controller the following functionalities can be activated/deactivated. When one setting is transferred to the unit, a short acoustic signal is emitted and a green led flashes.

FUNCTIONALITY	DESCRIPTION		CONTROLLER BUTTON	ICON	LED	ACOUSTIC SIGNAL
Airflow direction
Alternate	The unit runs in extract/intake at the selected speed: the inversion time is automatically defined thanks to the integrel temperature sensor (comfort mode).				green	short
Extract	The unit runs in extract only at the selected speed.				green	short
Intake	The unit runs in intake only at the selected speed.				green	short
Mode (active only if the airflow direction is set on alternate)
Comfort	Optimisation of the acoustic and thermal comfort. The inversion time varies automatically from 40÷120 seconds, thanks to the integral temperature sensor. The first time cycle is of 70 seconds, then it varies automatically according to the detected temperature conditions.			COMFORT	green	short
Efficiency	Optimisation of the thermal efficiency. The inversion time is fixed at about 70 seconds.			EFFICIENCY	green	short
Continuous running speed
	Quantum NEXT100	Quantum NEXT150
Speed 1	10m3/h	20m3/h			green	short
Speed 2	14m3/h	30m3/h			green	short
Speed 3	17m3/h	40m3/h			green	short
Speed 4	21m3/h	50m3/h			green	short
Speed 5	25m3/h	60m3/h			green	short
ON/OFF
	Unit can be switched on or off			OFF	red	long
				LCD ON	green	short
BOOST speed
	The unit runs at speed 5 (maximum) for 15 minutes, in extract only; then it returns to the previously selected mode/speed. The BOOST speed cannot be activated if the controller is OFF.				fixed blue	short
Free cooling
	The unit runs in "extract only" or "intake only" to avoid heat recovery when not needed.				green	short
Filter reset
	Every 3 months a yellow warning led switches on (fixed light) to indicate that the filters have to be maintained. Press the dedicated button for 5 seconds to reset the timing.			FILTER RESET	yellow	short
Smart humidity control
	When the humidity sensor detects a quick variation of the Relative Humidity level, the running speed automatically increases to the next higher speed. After 10 minutes from the last quick RH variation, the unit returns running at the selected speed. The smart humidity control is active if the airflow direction is set on alternate or extract only: if speed 5 has been selected, no speed increase happens. To disable this functionality, press the button for 5 seconds: on the top side of the LCD display the symbol is shown.				flashing blue
Antifrost
	This functionality prevents frost building up on the heat exchanger due to extremely cold air. When it is activated, the unit runs in extract only at speed 1, for 30 minutes.				fixed red
Acoustic signal
	Any time a setting is transferred from the controller to the unit, a short acoustic signal is emitted. This can be deactivated by pressing the button for 7 seconds, after when a green led flashes to indicate that the acoustic signal is off. To reactivate the acoustic signal repeat the same operation for 7 seconds until the led becomes green and an acoustic signal is emitted.				green	short

BACK UP BUTTON
In case the remote controller gets lost or the batteries are dead, ON and OFF position can be selected from the on board touch button (J), pressing the button for at least 3 seconds.

SYNCHRONISATION OF A NUMBER OF UNITS
It is possible to synchronized up to 10 units contemporaneously, through wire (2 pole twisted pair type, max 30m length) so to have mode and inversion time synchronized. When the unit is switched on for the first time, the rotation direction of each unit (clockwise or anti-clockwise) is automatically established. Other functionalities like speed, smart humidity control and boost, continue to be controlled independently on each single unit. Wiring diagram as per fig. 16B.

MAINTENANCE

Maintenance can be carried out by the user as shown in figures 49-65.
