Description

The present invention relates to a method for controlling the so-called "heatwave" closure of a motorized, non-solar shutter, ensuring automated movement of the shutter in the event of a confirmed heatwave. The objective is to automate the shutter's closure through a "heatwave" mode, specifically based on the temperature rise, with closure occurring only if the climatic conditions are considered characteristic of a heatwave. The most immediate aim of the invention is to improve living comfort in a home, given the ever-increasing likelihood of heatwave episodes. Secondarily, in the case of a building equipped with air conditioning systems, proper management of the positioning of solar shutters can lead to energy savings by reducing the need for air conditioning during hot summers. The motorized shutters covered by the invention are equipped with an electric drive motor connected to the mains voltage; the motor is also connected to a control unit, generally an electronic board that includes the components for processing information to control the motor. The document US 10859985 B2 This document describes a method for the automated control of the closing of a non-solar shutter driven by an electric motor. The motor is connected to a control unit equipped with telecommunications means and is controllable by means of an individual remote control that can be programmed by the user to operate the shutter in either an automated or a non-automated mode. An additional remote control is associated with the shutter, this remote control including means for measuring the ambient temperature. The method involves measuring the ambient temperature at regular intervals using the additional remote control. Methods for closing shutters during periods of extreme heat are already known, particularly for so-called solar shutters driven by a motor powered by solar energy obtained via solar panels. A solar irradiance sensor is added for control purposes. In this case, it is the solar irradiance measurements that are used to determine the presence of extreme heat conditions, thus triggering the shutter closure. For the non-solar shutters targeted by the invention, which can be connected to a home automation system, an automated so-called twilight closing is known, programmable based on a clock that controls the closing of connected shutters at a pre-programmed time, for example entered by The user is programmed to set a timer that theoretically corresponds to a time close to sunset. This is therefore a time-based programming method. If the home automation system is connected to the internet, the shutters can potentially be automated to close based on the temperature forecast provided by the regional weather service, data accessible on the internet. The resulting automation is not based on a parameter measured at the shutters' location, but rather on a purely theoretical and virtual test value. Automation, if programmed on such a basis, suffers from a lack of precision, as a weather forecast temperature is not a true reflection of the actual conditions on the ground. Above all, such a program struggles to accurately account for the emergence of heatwave conditions at a specific time and place, because a predicted temperature for a region never reflects the numerous potential specificities of the dwellings whose shutters need to be controlled. These specificities can be architectural, such as wall depth and window distribution/size, or situational, such as the orientation of the windows (north/south) or the building's location (wooded or not), etc. Many examples could be given of differences that necessitate different heatwave treatment for dwellings located in the same area, thus making automation highly dependent on the context. In this regard, it seems obvious to say that the ambient temperature measured inside a building, and therefore directly felt by the inhabitants whom we seek to protect from the rigors of the heatwave, must be an essential factor to take into account. The objective of the present invention is therefore to provide an assessment of the heatwave conditions specific to each dwelling, in order to implement an automation process that is as closely adapted as possible to the reality experienced by people living in buildings subjected to high temperatures. In this respect, the method of the invention aims to take as a reference value the ambient temperature in the part of the building where the heatwave-related shutter closure is to be automated. To this end, the invention consists of a method for automatically controlling the heatwave-related closing of a non-solar shutter, conventionally driven by a electric motor, the motor being connected to a control unit equipped with telecommunication means, and controllable by means of an individual remote control capable of being programmed by the user between an automated operating mode and a non-automated operating mode of the shutter, an additional remote control being
