Thermostat - STO 011/STS 011

STO, STS

The mechanical thermostat is a two state regulator with small hysteresis. The setting wheel has an anti frost assurance. The housing ensures an optimized air circulation around the bimetal.

 

STO 011: Thermostat (NC); contact breaker for regulating heaters. The contact opens when temperature is rising.

 

STS 011: Thermostat (NO); contact maker for regulating of filter fans and heat exchangers or for switching signal devices when temperature limit has been exceeded. The contact closes when temperature is rising.

  • Thumbwheel setting dial
  • Small hysteresis
  • High switching capacity
  • Anti frost assurance
  • Optimized housing for better air flow
