Brief description
Thermostats control and monitor thermal processes.
The JUMO heatTHERM is available as temperature controller TR, temperature monitor TW (type
602030), safety temperature monitor STW, or safety temperature limiter STB (type 602031).
The panel-mounted thermostat operates according to the fluid expansion principle. The electri-
cal switching element is a snap-action switch.
The panel-mounted thermostat is RoHS-compliant and cadmium-free.

Technical data
Switching function
Data Sheet 602031 Page 2/10
Temperature controller TR /
temperature monitor TW
If the temperature on the temperature probe exceeds the setpoint value, the microswitch is activated by the
transmission mechanics and the electrical circuit is opened or closed. If the temperature falls below the
selected setpoint value (by the amount of the switching differential), the microswitch is reset to its initial position.
Safety temperature monitor
STW
If the temperature on the temperature probe exceeds the setpoint value, the snap-action switch is activated
and the electrical circuit is opened or closed. If the temperature falls below the selected setpoint value (by the
amount of the switching differential), the snap-action switch is reset to its initial position.
If the probe has cooled down to a temperature below approx. -20 °C the electrical circuit opens - however it
closes again when the temperature rises.
If the measuring system is destroyed (i.e. if the expansion fluid emerges) the pressure in the diaphragm drops
and permanently opens the electrical circuit.
Safety temperature limiter
STB with restart lock and
self-monitoring
If the temperature on the temperature probe exceeds the switching point, the snap-action switch is activated,
the electrical circuit is opened, and the snap-action switch is mechanically locked.
The unlocking difference depends on the control range. Precise values can be attained from the respective
device type. They are also available upon request.
If the probe has cooled down to a temperature below approx. -20 °C the electrical circuit opens - however it
closes again when the temperature rises.
If the measuring system is destroyed (i.e. if the expansion fluid emerges) the pressure in the diaphragm drops
and permanently opens the electrical circuit. Unlocking is no longer possible.
Temperature compensation
When the ambient temperature on the switching head and the capillary deviates — from the calibration ambient temperature of +22 °C — a switching point offset occurs. This switching point offset is reduced to a minimum due to the temperature compensation.
