Thermostat - compact thumbwheel

Type STO 011 / STS 011 thermostat - an SPST regulator with small hysteresis. The housing design ensures optimized air circulation around the sensor element.

Thermostat NC (normally closed): Thermostat opens on temperature rise (red thumbwheel) - for regulating heaters or for switching signal devices when temperature has fallen below the minimum value.

Thermostat NO (normally open): Thermostat closes on temperature rise (blue thumbwheel) - for regulating filter fans, heat exchangers, cooling devices or for switching signal devices when temperature limit has been exceeded.

Advantages

• Adjustable thumbwheel setting
• Compact size
• Small hysteresis
• High switching capacity
• DIN rail mountable
