Important note: The contact system of the regulator is subjected to environmental influences, thus the contact resistance may change. This can lead to a voltage drop and/or self-heating of the contacts.Thumbwheel setting dial Small hysteresis High switching capacity Anti frost assurance Optimized housing for better air flowThe 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.STO 011 Thermostat (NC)Heater STS 011 Thermostat (NO)e.g. Fan STS 011 (NO) ThermostatSignal Device min: 24V; 20mAEnclosure heaterFilter fan, cooling equipment, signal devicePart No. Operating voltage3 Setting range01170.0-00 AC 230 V 5 to 60 %u00b0C01170.0-01 AC 230 V 40 to 140 %u00b0F01170.9-00 AC 120 V 40 to 140 %u00b0F01170.9-01 AC 120 V 5 to 60 %u00b0CThe anti frost assurance is a symbol on the setting scale of the NC thermostat (STO 011) at +11%u00b0C.
