Abstract

1293724 Automatic control of temperature LANDIS & GYR A G 20 April 1971 [28 April 1970 1 Feb 1971] 10238/71 Heading G3R A temperature control arrangement of a central heating installation, comprises a bridge circuit (not shown), including temperature responsive resistors and adjustable potentiometers R10, R11, Fig.1, the slidable contacts 12, 13 of which are movable by pegs 8, 9 respectively, whereby to adjust the linear operating characteristic relating the forward flow temperature of a boiler outlet to a sensed temperature (e.g. outside temperature). The pegs are linked by a graph indicator member 19 representing the said characteristic, and which is fixed to one peg and movable in the other. The indicator 19 is viewable against a coordinate scale on a front plate 16 and which has flow temperature as ordinate and outside temperature as abscissa. The slider contact 12 of R10 is carried by an insulating member 6 which also carries the resistor R11. When peg 8 is linearly moved to adjust slider 12, the resistor R11 will be moved relative to its slider 13. Thus linear movement of peg 8 results in parallel displacement of the operating curve of a heating installation control, and movement of peg 9 results in a change in the slope thereof. A slider contact 15 connects one end 14 of R11 to a contact track (not shown) and thence to the bridge circuit. In an embodiment, Fig. 2 (not shown) both resistors are stationary, a first resistor being engaged by two slider contacts of a first adjuster and by one slider contact of a second adjuster. The second resistor is engaged by only one sliding contact.
