Modul AD02

Product detailed description

The Atmos AD02 module is commonly used in installations involving solid fuel boilers, particularly in systems requiring automated ventilation control. It supports both residential and commercial applications where precise fan regulation is essential. Installers typically integrate the module into boiler automation setups, ensuring synchronisation between combustion processes and exhaust airflow. Correct positioning and wiring are critical for system performance.

This relay operates as an intermediary component between boiler sensors and the exhaust fan motor. It is designed for environments subject to heat fluctuations and mechanical vibrations, typical of boiler rooms. Proper installation ensures reliable fan activation during combustion cycles and deactivation when idle, improving overall efficiency and reducing wear.

Technical parameters

Installation and connection

The installation process begins with selecting a secure mounting location near the boiler controller and exhaust fan. Connectors are typically screw terminals or push-in type, depending on the boiler model. The module should be wired according to the manufacturer’s schematic—ensuring correct polarity and insulation. Verify continuity using a multimeter before energising the circuit.

• Confirm that all connections are tightened securely to prevent intermittent faults.
• Check for proper grounding to avoid electrical noise interference.
• Avoid proximity to high-voltage components to reduce electromagnetic interference.
• Label all wires clearly for future reference and maintenance.
• Ensure the module is mounted in a dry, dust-free environment to prolong service life.

Compatibility and accessories

The AD02 is specifically designed for use with Atmos solid fuel boiler models. It is typically used alongside boiler control units, exhaust fans, and temperature sensors. For complete functionality, ensure that the control unit and fan motor are compatible with the relay’s signal output. Additional components such as junction boxes and protective enclosures may be required depending on the installation site conditions.

Technical background for designers

The Atmos AD02 functions as a low-power relay that activates the exhaust fan based on input signals from the boiler controller. Internally, it likely contains a solid-state or electromechanical switch, depending on the design. The housing is constructed from thermally stable materials to withstand ambient heat in boiler rooms. Integration into the control loop requires careful consideration of timing and signal synchronisation to prevent over-fan operation or delayed response times. Long-term reliability depends on consistent power supply and minimal exposure to moisture or corrosive gases.

Service and operation

During routine maintenance, inspect all electrical connections for signs of overheating or corrosion. Use a multimeter to test continuity and resistance values periodically. Check for abnormal noise or vibration during fan operation, which may indicate relay failure. Replace the module if it fails to respond to control signals or exhibits erratic switching behaviour. No scheduled service intervals are specified; servicing should occur only when operational issues arise.

Frequently asked questions

Can the Atmos AD02 be used with non-Atmos boiler systems?
It is specifically designed for use with Atmos solid fuel boilers. Using it with other brands may require additional verification of compatibility with control systems and fan specifications.

Does the module support manual override of the fan function?
No manual override is mentioned in the technical description. Fan control is automatic and dependent on signals from the boiler control unit.

What are the environmental requirements for the installation site?
Install the module in a dry, dust-free area away from direct heat sources. Ensure adequate ventilation around the device to prevent overheating.

How does the module handle voltage fluctuations in boiler systems?
According to the manufacturer’s technical data sheet, the module is designed to operate within standard electrical tolerances found in boiler environments. Specific values are available in the technical documentation.
