Square-to-round duct transition kit enables 024-048 size units to be fitted to 14 in. (355.6 mm) round ductwork.

Thermidistat Control coupled with the system’s variable speed indoor blower delivers Carrier’s patented IdealHumidity Technology that allows for even greater humidity control. Along with more precisely controlling temperature and humidity, the Thermidistat offers full seven-day programmability allowing you to further customize your comfort and energy savings.

Thermostats provide control for the system heating and cooling functions. Thermostat models are available in both programmable and non-programmable versions.

Crankcase Heater provides anti-floodback protection for low-load cooling applications.

Compressor start kit assists compressor start-up by providing additional starting torque on single phase units and prolongs compressor motor life.

Rigging kit includes lifting brackets which are inserted into the unit base rigging holds to lift unit for rooftop applications.

Low-ambient kit (Motormaster II control) allows the use of mechanical cooling down to outdoor temperatures as low as 0_F (-17_C) when properly installed.
