Description:
KNX installation in a detached single-family house with swimming pool.
By means of the installed KNX devices we integrate:
Climate control: The property has air-conditioning by fan coils and underfloor heating. Airconditioning machines are water-fired, controlled by KNX fancoil actuators. In each room there is a touch screen that acts as a thermostat. With the same thermostat, we can control the air conditioning and underfloor heating, as well as control the lights and blinds in the room.
Lighting: : The dwelling has On/Off type lights and in some circuits their intensity can be regulated. The lighting system chosen for dimming is the DALI system, which uses a DALI-KNX gateway to control the switching on and off of the luminaire, as well as dimming from the KNX pushbuttons and pushbutton panels installed in the home.
Curtains. KNX actuators can be used to control the blinds in the home individually and together (all at the same time).
Control of the engine room: In this dwelling we control two Hidrokit ofAltherma, via a gateway directly to KNX. With this control, the user can select the flow water temperatures for air-conditioning, either hot or cold. In addition, the temperature of the domestic hot water can be set to the desired temperature. To simplify it for the user, operating modes have been established, where the user, by pressing a single button, sets the mode of operation of the system. For example: In HEAT mode, the user can choose the option of Heat by fan coils or underfloor heating, simply by pressing a button. But behind all this there are several manoeuvres that are done, such as turning the 3-way valves in direction Floor/Fancoils, changing the flow temperature of the water, etc.
Control and visualisation: A web server has been installed in this house, which enables us to create a customised visualisation for the user. Through this web server, the user has full individual and centralised control of the entire KNX installation, whether he/she is in the home or away from it, by means of his/her mobile device.
Functionalities:
By creating scenes, the user can perform various functions with a single gesture and modify them as desired, using the mobile device itself.
In this project, the user has control of the entrance doors, so that even if he is away from home, he can open the door.
