Description
The Bard HVAC CMH-20 Low Ambient Control is a precision-engineered accessory designed to allow air conditioning and heat pump systems to operate reliably in cold outdoor temperatures. Without low ambient controls, refrigerant pressure can drop below safe operating thresholds during cool or cold weather, causing compressor damage or system lockout. The CMH-20 addresses this challenge by modulating condenser fan operation to maintain proper head pressure, protecting the system and ensuring consistent performance across a wide range of outdoor conditions.
