Heat Controller 17122000015312 Low Ambient Kit
For contractors servicing Comfort-Aire and Heat Controller split systems, the 17122000015312 Low Ambient Kit is the essential field-installed accessory for maintaining head pressure control during low outdoor temperature operations. This kit is specifically engineered for models like the SMH18SC and A-SMA24SC-1, allowing the system to operate safely in cooling mode even when ambient temperatures drop as low as -40°F. By regulating the condenser fan motor speed or cycling the fan based on liquid line pressure, it prevents evaporator freeze-up and ensures refrigerant flow remains within the thermal expansion valve (TXV) design parameters. This hardware is a critical component for server rooms, telecom hubs, and cold storage applications where year-round cooling is mandatory. The low ambient controller integrates directly with the defrost board and main contactor, providing a seamless interface for HFC-410A systems. Note that for optimal performance and compressor protection, the use of a crankcase heater is required in conjunction with this installation.
Key Benefits
- Prevents evaporator icing by maintaining stable saturated condensing temperatures.
- Extends the operational range of split system heat pumps and AC units down to -40 degrees Celsius.
- Protects the scroll compressor from liquid slugging during low ambient cooling startups.
- Genuine OEM replacement part (also known as CMF17122000015312) ensures exact fit and electrical compatibility.
Common Questions
Will this work with ECM fan motors?
This specific kit is typically designed for permanent split capacitor (PSC) and shaded pole motors; always verify your motor type before attempting variable speed fan control integration.
Is a crankcase heater necessary with this kit?
Yes, a crankcase heater must be installed to prevent refrigerant migration to the oil during the off-cycle in cold environments.
Does this kit require a TXV?
Yes, head pressure control kits require a non-bleed thermal expansion valve to maintain the pressure differential required for the refrigerant circuit.
