<p>PCT No. PCT/FI86/00112 Sec. 371 Date Jun. 1, 1987 Sec. 102(e) Date Jun. 1, 1987 PCT Filed Oct. 9, 1986 PCT Pub. No. WO87/02539 PCT Pub. Date Apr. 23, 1987.The invention relates to a control and switching apparatus for electric heating, comprising a micro-processor-based operation control unit (2) provided with control switches, and a regulating circuitry unit (5) associated with said control unit and comprising a plurality of regulating circuits. At least some of the regulating circuits are connectable to electronic sensors (8), whereby the combined effect of measuring messages fiven by said sensors, control data from the operation control unit (2) as well as set values (6) selected by the regulators provides the basis on which the regulating circuits (5) are adapted to control the ON/OFF-switches of electric loads, said switches being triac-switches (9a). One regulating circuit can be modified to operate as a regulating circuit suitable for controlling an electric sauna stove, said circuit being connectable, by means of a selector device, in power transposition with one or several other regulating circuits.</p> |
