The FZ4A fan coil has the proven technology of fan coil units with Puron® refrigerant as well as vertical and horizontal applications. The design features contoured condensate pans with rugged drain connections, ensuring that little water is left in the unit at the end of the cooling duty cycle. The lack of standing condensate and corrosion free pans improves IAQ and product life, features homeowners appreciate.
Standard features include grooved tubing and louvered fins. Coil circuiting has also been updated to make the most of all heat pumps and air conditioners. Units come with solid state fan controls, 1-inch (25mm) thick insulation with R-value of 4.2, multi-speed motors, and fully-wettable coils. Units can accommodate factory- and/or field-installed heaters from 3 to 30 kW.

The new FZ fan coil will allow for a higher SEER, 2-stage option in a smaller space than previously available. Features of the FZ fan coil include two-stage blower operation, wider airflow range than FB4C and FX4D, lower continuous airflow option than FB4C and FX4D, and single and two-stage outdoor unit compatibility.

The FZ4A fan coil design is loaded with popular features. These fan coils utilize the latest in electronic commutation motor (ECM) technology through the use of high efficiency, multi-tap ECM motors allowing reliable air delivery with increased static pressure. It comes in a pre-painted (taupe metallic) galvanized steel casing and a factory-supplied power plug for ease of installation. The FZ4A unit is shipped with a factory-installed Puron refrigerant TXV FZ4ANP (024-061).
