Description
CFA-24V Electronic Freeze Protection Alarm with Digital Display & Dual Relays
The CFA-24V is an advanced electronic freeze protection alarm, specially designed for air heating systems that use water as the heat carrier. This intelligent alarm system with digital Display monitors the water temperature in the heating coil and intervenes immediately in case of imminent freezing.
Key Features
- Operates on 24V AC, ideal for industrial and HVAC applications
- Automatic control of the regulating valve at decreasing temperature
- Dual relay outputs for reliable alarm signaling
- Digital Display for precise temperature indication
- Compatible with multiple temperature sensors (Pt100, Pt1000, Ni1000, Calectro NTC/PTC)
- Temperature adjustment from -3°C to +3°C in increments of 0.1°C
- Automatic alarm activation in case of Sensor faults (short circuit or breakage)
- Easy installation via DIN-rail mounting
How does the CFA-24V work?
The CFA-24V measures the water temperature in the heating coil via a connected temperature Sensor. Under normal conditions, an external controller or DUC regulates the temperature through a control signal (0-10V or 10-0V).
If the temperature drops without response from the controller, the CFA takes over and automatically controls the valve. When the temperature falls below the preset alarm value, the relay outputs switch and the control signal is set to 100% to prevent frost damage.
Easy installation & broad Sensor compatibility
The CFA-24V is designed for DIN-rail mounting and suitable for standard enclosures. It supports a wide range of temperature sensors, including Pt1000 (factory default setting).
