Heat Controller 17122000015312 Low Ambient Control Kit for HVAC Systems

The Heat Controller 17122000015312 Low Ambient Kit is designed to enable air conditioning systems to operate efficiently when cooling is required during low outdoor temperatures. This essential HVAC accessory maintains proper system pressures and prevents performance issues in cold weather conditions.

Key Features:

• Regulates condenser fan speed to maintain optimal head pressure in low ambient conditions
• Prevents evaporator freeze-ups and low pressure cut-outs during cold weather operation
• Uses temperature sensor to monitor and automatically adjust fan motor speed
• Enables reliable cooling operation when outdoor temperatures drop below normal operating range
• Helps protect compressor from liquid slugging in low temperature conditions

This low ambient control kit works by slowing the condenser fan to maintain proper head pressure by varying airflow through the outdoor coil. A temperature sensor mounted on the condenser coil continuously monitors liquid line temperature and adjusts motor speed accordingly to prevent system freeze-up and maintain efficient operation.
