Description
The Bard HVAC CMA-28 is an OEM low ambient fan control designed to maintain reliable condenser fan operation during cold outdoor conditions. By regulating fan cycling in response to ambient temperature drops, this control helps protect the refrigeration circuit from low-pressure faults and ensures consistent system performance year-round — even in challenging winter environments.
Key Features
- OEM Bard HVAC replacement part for compatible equipment models
- Controls condenser fan operation under low ambient temperature conditions
- Helps prevent low-pressure lockouts caused by cold weather operation
- Supports stable head pressure and refrigerant circuit performance
- Designed for use with Bard wall-mount and packaged HVAC systems
- Direct OEM replacement for simplified installation and reliable fit
Why Low Ambient Fan Control Matters
In cold weather, condenser fans can cause refrigerant head pressure to drop too low, leading to nuisance lockouts or compressor damage. The CMA-28 addresses this by modulating or cycling the condenser fan to maintain proper operating pressures, extending equipment life and reducing service calls during the heating season.
Application
- Compatible with select Bard HVAC wall-mount and packaged air conditioning units
- Ideal for installations in northern climates or areas with significant seasonal temperature variation
- Suitable for light commercial and commercial HVAC applications
