Operation; Maintenance And Service - aerauliqa Quantum HR 100 Installation Manual

OPERATION

In both versions, the unit pulls air out for 70 seconds, then it pushes air in for the same
time.
When heated air is pulled (extracted) from inside the room, it warms up the heat exchanger;
when the cold air is pushed (supplied) in the room, it gets preheated, recovering most of
thermal energy which would be otherwise lost in the ventilation process.
The unit runs at the speed selected by activating the two-position switches "S1", "S2"
and "S3" of the CTRL-S (accessory fig. 64). The same functionality can be achieved with
CTRL-S or with 3 two-position switches.

S3 switch activates the "Free cooling " (Bypass) mode, which stops alternate flow and
keeps the fan in extract mode only, to avoid the heat exchange when necessary. The
front cover LED indicates when the Free cooling mode is on.
An automatic "Boost"mode can be achieved through a dedicated switch or room sensors
like SEN-HY, SEN-PIR or SEN-CO2, connecting such switch in parallel to the S2 switch.
Wiring diagram: fig. 19.
Ensure that the electric wiring to L and N is done correctly; an incorrect
connection will lead to malfunction or permanent damage of the fan
SyNCHRONISATION
When the units are installed in pair, they must be synchronised so that when one unit is
extracting, the other is supplying, and viceversa.
This is achieved by setting the dedicated jumper. (fig. 21A-21B).

MAINTENANCE AND SERVICE

Maintenance can be carried out by the user as indicated at page 13.
Service must be perfmormed only by technically qualified personnel in accordance with
local rules and regulations. Make sure that the mains supply to the unit is disconnected
(page 14).
Cleaning of the heat exchanger can be performed from outside as well.
