Abstract
A heating, ventilating and/or air conditioning apparatus includes an air heating duct containing a primary radiator of the hot fluid flow type and an electric auxiliary radiator, a stream of air being passed through both radiators. It also includes a signal processing module for governing operation of the apparatus in accordance with atmospheric parameters set by a user, and a temperature sensor for measuring the temperature of the fluid flowing in the primary radiator. The signal processing means include a regulating module which is arranged to make a selective decision as whether to energise the auxiliary radiator, and if so, to what extent, in accordance with the parameters set by the user and at least the measured temperature of the fluid in the primary radiator.
