Temperature regulating system for the control of temperature in a room

A temperature regulating system for controlling the temperature in a room comprising a feeler gauge adapted to control the supply of energy to a radiator system in the room, said gauge being adapted to be suspended in a room and comprising a radiation sensor and a convection sensor for sensing the radiation and air temperature respectively, and a wireless transmitter means, said convection sensor being operatively connected to said transmitter means to control the transmitter means to emit signals depending on the radiation and air temperature sensed at regular intervals, and a receiver controlling means for receiving said signals and regulating the supply of energy to the radiator system, said convection sensor comprising a thermal sensitive member for sensing air temperature and having properties which change in response to temperature changes, said radiation sensor comprising a thin-walled hemisphere of good heat-conducting material having a black mat radiation absorbing surface connected in heat-conducting relationship with said convection sensor, said transmitter means comprising a printed circuit including said convection sensor therein so that signals representing said changed properties are transmitted by said transmitter means to said receiver, programming means in said receiver whereby the desired temperature can be programmed in the receiver, and means to compare said signals with said desired temperature.
