Abstract

A time-controlled heat regulator has the capability of controlling a heat supply so as to lower the temperature of a heated area during nighttime and to increase the supply of heat in dependence upon outside temperature to begin raising the temperature of the heated area in advance of a point in time at which the heated area is desired to attain a specified temperature. The heat regulator has a time-controlled variable resistor interconnected in a bridge circuit, the variable resistor being cut into the circuit at the beginning of a longest chronologically possible heat-up phase dependent on the outside temperature. The resistance of the variable resistor changes over time until reaching coincidence with the resistance value of an outside temperature sensor. The length of time of the heat-up phase is thus dimensioned backwardly from the time of reaching the desired area temperature as a function of the prevailing outside temperature.
