Where to Buy


Standard Options

Low Ambient Protection

Protects the system from cold temperatures below 5°C (40°F).

Available Options

Extreme Climate Protection Bundle

For Self-Contained Ducted systems: Contains an integral compressor crankcase heater and controls to protect the system against low temperatures (required when inlet air to the condenser coil is below 40°F/5°C). The bundle also contains an integral high capacity condenser fan and coil for operation at elevated ambient temperatures. This bundle should be considered when inlet air to the condenser coil is above 100°F/38°C (condenser air inlet cannot exceed 120°F/49°C).

For Ducted Split systems: Unit protection in extreme climate conditions (on the condenser section only). It is required for continuous operation in climates that fall below 20°F. Enables the system to operate in temperatures as low as -20°F.


Protects wine cellars from dangerously low temperatures. Adjustable activation from 2 - 6°F (-17 - -14°C) below your setpoint.
