The room thermostats are fitted with liquid-filled helix probes made of copper or stainless steel that act as temperaturedependant pressure probes. A change in temperature causes a pressure change in the probe, which is transferred to a switch by a bellows system or a diaphragm. A compression spring acts as a counteracting force. The switching values are set by changing the initial stress of the compression spring with a setpoint spindle.
