English Siemens QAF64.2-J Frost monitor, continuous and 2-point, capillary 2000 mm
• Continuous and 2-point
• Fully active capillary tube sensor
• Frost indicator with red LED
• Measuring range 0..15°C
• Frost switch point setting range 1...10 °C
• Test switch for frost simulation
• Switch for automatic or manual reset function
• Continuous P controller for start-up circuit
• Limit value contact for system control
• Operating voltage AC 24 V
• Signal voltage DC 0...10 V
Area of application:
In ventilation and air conditioning systems, air side:
• Typical: Air-water heat exchangers for air heating, where cold air inflow can cause a risk of freezing
• Where fans must be switched off, heating valves opened, and air dampers closed to protect against freezing
• Where the risk of frost must be reported
Additional information:
Accessory AQM63.2 (3 deflection brackets and 3 spacers) is required to attach the capillary tube.
Summary: With active signal input and output for valve control
