<P>PROBLEM TO BE SOLVED: To provide an electric circuit for an electric floor heating system in an upper limit threshold current is set even for a stable state a predetermined time after rush as well as during rush, to prevent suspension of operation in a multiple dwelling house. <P>SOLUTION: In the electric circuit for electric floor heating system, an upper limit threshold current value is set for a stable state a predetermined time after rush, in a control circuit of a controller of the electric floor heating system (1), and a means is provided for automatically reducing the power-supply area of a heat generating resistor when the current exceeds the upper limit threshold current value, so as to reduce the electric capacity of a main line (2). <P>COPYRIGHT: (C)2012,JPO&INPIT |
