A method for the temperature control, in light of the temperature setpoint, of a climate system comprising a plurality of climate devices (110, 111, 140, 141) of a premises comprising several rooms, in the presence of a change to the temperature setpoint in one of said rooms, said method comprising the following steps: a. obtaining a first temperature behavior model of the premises, called initial model; b. adapting the initial model to the actual temperature behavior of the premises by analyzing the response to a solicitation of the climate system, to obtain a second model, called adapted model; c. calculating, from the adapted model, the temperature variation in each room based on the modification (531, 532, 533, 534) of the operating conditions of one of the climate devices of the climate system; d. deducing, from step c), the load conditions of each climate device of the climate system to respond to the temperature setpoint modification in the room of the premises; e. applying the load rates determined in step d) to each climate device of the climate system; characterized in that: - the climate system comprises presence detection means in one of the rooms of the premises, called monitored room, and a computing module; and - the method further includes the steps consisting of: f. obtaining (310, 315) an occupancy and non-occupancy calendar of the monitored room and first and second setpoint temperatures, the second setpoint temperature corresponding, for the climate system, to a lower energy consumption than the first setpoint temperature; g. changing the temperature in the monitored room by applying steps d) and e) to said monitored room with a temperature setpoint corresponding to the second temperature setpoint at the beginning of a non-occupancy period of said room; h. computing, from the adapted model, a third model called inverse adapted model making it possible to compute a time to reach a temperature in a room; and determining, from said inverse adapted model, the time, denoted t a, needed to reach the first setpoint temperature in the monitored room; i. applying steps d) and c) at the moment preceding, by t a, the occupancy date of the room, with the first setpoint temperature as the setpoint temperature. a. obtaining a first temperature behavior model of the premises, called initial model;
