Siemens QAF81 Series Thermostats, 15(1.2)A Contact Rating, -5-15 °C Temperature Range - QAF81.6
This thermostat is specifically designed for air temperature monitoring in HVAC systems. The robust aluminium diecast housing ensures durability, while the temperature monitoring is facilitated via a gas-filled capillary system. Operating within a temperature range of -5 to +15 °C, this frost protection solution is essential for safeguarding LTHW heating coils from frost damage.
Features & Benefits
• Designed for reliable frost protection in HVAC systems
• Automatic reset functionality enhances operational efficiency
• Dual measurement capability over a capillary length of 30-100cm
• Features a single pole changeover switch for versatile control
• Temperature settings adjustable between -5°C and +15°C
• IP54 rated with optional IP65 protection for harsh environments
Applications
• Used for monitoring temperatures of LTHW heating coils
• Ideal for installation in ventilation and air conditioning systems
• Effective to prevent frost damage in industrial settings
• Suitable for integration in automated heating systems
• Frequently used in commercial HVAC solutions
How does the temperature setting impact system functionality?
The temperature setting directly influences the activation of frost protection mechanisms, ensuring the heating system operates effectively and prevents frost formation when temperatures drop.
What is the significance of the capillary length for operation?
The capillary length of 30-100cm aids in accurately sensing temperature changes throughout the designated area, enabling timely adjustments to heating elements and preventing system failures.
Can this thermostat work in outdoor environments?
Yes, when properly installed within a suitable protective housing and if the ambient temperature is managed, it can function effectively even in outdoor applications by mitigating the risk of frost damage.
