Мініатюрний термостат сто 011 / STS 011

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.
