2.2. Operating principles
To use the unit well, it is necessary to understand the following principles:
The unit is designed to reduce condensation phenomena in the premises. The principle consists in insufflating air under low pressure
into the rooms to be treated in the necessary and sufficient quantity.
This principle is based on the fact that moving air dries the walls (principle used in industry, particularly for demisting motor vehicle
windows.
In order to understand the other action of the system, one thing is obvious: indoor air is above all outdoor air that is more or less
humid but which, in addition to the humidity it already contains,
takes on the humidity produced by the use of the
rooms
(cooking vapours, baths and showers, productions of the human body etc....).
The insufflation system will therefore proceed to renew this polluted indoor air with fresh outdoor air, pushing the stale air towards
the openings made for its evacuation.
Furthermore, heating the outside air before blowing it in will reduce its relative humidity.
It is understood that the amount of humidity the air can contain is directly related to its temperature and that the warmer the air is,
the more humidity it can contain.
It is therefore very important to maintain a regular temperature and avoid
wide variations
(day/night period for example or occupied/unoccupied premises). Moreover, lowering the heating significantly
saves energy, but when you want to restore a comfortable temperature, you have to consume much more than is necessary to heat
all the elements of the building and the furniture.
The installer made the settings to the device according to the volumes of the rooms to be treated and the layout of the unit.
He cannot take into account your lifestyle (frequency of door opening, propensity to create water vapour from the various household
appliances, more or less intensive use of the sanitary facilities).
Depending on your lifestyle, you can intervene on all parameters such as temperature setting, air flow rate, pre-programmed mode,
etc....
In all cases, your unit will have to operate continuously to maintain constant movement.
If the unit is connected to the Internet.
The module, called Etairbox, is connected to the box via a network cable. It enables the CTA4 control box to connect to the internet.
The CTA4 will therefore be able to send and receive information on a server located in the Murprotec platform. You can access an
online account reserved for you.
The control box communicates with the machine via a cable and with Etairbox via Radio Frequency (not Wifi nor Bluetooth).
No personal data are transmitted to the machine and the connection is secure.
