Hot Air Thermostats

WTHc series

Special features

•With microswitch

• Device combination consisting of 3 individual devices

• Protection class IP 40 or IP 54

• Tested according to DIN EN 14597

Brief description

Thermostats are used to control and monitor thermal processes.

The thermostats of the WTHc series are suitable for the use in hot air systems acc. to DIN 4794
and consist of 3 separate measuring and switching systems with the following functions: tem-­perature controller TR, temperature monitor TW, and safety temperature limiter STB.

In the event of a malfunction, the STB switches the monitored machine line to an operational
safe status.

Hot air thermostats operate according to the fluid expansion principle. The electrical switching
elements are microswitches.

Switching function

Temperature controller TR and 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.

Temperature monitor TW and safety temperature limiter STB

The microswitch can be manually unlocked once the dangerous temperature drops by approx.
10 K. The microswitch can be manually unlocked once the dangerous temperature drops by ap­prox. 10 K.

Self-monitoring for the safety temperature limiter STB

If the measuring system is destroyed (i.e. if the expansion fluid escapes) the pressure in the
membrane of the STB drops and permanently opens the electrical circuit. Unlocking is then no
longer possible. If the probe has cooled down to a temperature below approx. -20 °C the elec­trical circuit opens − however it automatically closes again when the temperature rises.
