The multi-stage chamber thermostat manufactures by the Swiss company Trafag has an adjusstable interstage distance between two switching points. Moreover, the hysteresis of the ambistat is unregulated and the electrical connections are located on the terminal block. There is also a choice of adjustment: external or internal.
