<p>1. A set point adjuster for a temperature controller for a heat source of a heating system for a building, comprising a bridge circuit, one branch of which includes a desired-value resistor (7, 8, 9) for selecting a desired room temperature whereas the other branch includes a series connection of a resistor (13) that is dependent on the outdoor temperature and of a fixed resistor (14), and the detector diagonal of the bridge comprises the slider (15) of the desired-value resistor and the junction (21) between the resistor that is dependent on the outdoor temperature and the fixed resistor and is coupled to an amplifier (18), the output of which is connected to the controller for the heat source, characterized in that the junction (21) between the resistor (13) that is dependent on the outdoor temperature and the fixed resistor (14) is connected to the amplifier (18) via a resistor (28 to 32) which is equivalent to a standard outdoor temperature, and a trimmer resistor (35) is connected in parallel to the amplifier (18) and is adjusted to a value which represents the temperature for which the heating system is designed.</p> |
