NEW! ECM Motor Option

This new ECM motor option includes 24V controls, a constant torque, permanent magnet, brushless DC motor, with 4 discrete speed taps that allow for precise air balancing.

The CW(*) is equipped with a control board that allows 24V 3-speed fan operation from a 3-speed wall mounted thermostat. Three compatible 3-speed thermostats are available from First Co.: manual changeover (#T420), auto changeover (#T421), and the all new “Autospeed 24V” (#T200 and #T201). The T200/T201 Autospeed 24V provides maximum comfort and efficiency by automatically varying the fan speed between High, Medium, and Low speeds, depending on room temperature and desired thermostat setting. (See P4. for additional information)

Standard Features: • 240V motor, 24V 3-speed fan control • 240/24V 3-speed control board (see description on Page 4) • Electrical service pullout (not on 277V models) CWX Thru-Door 120/24V YES 208/230/24V YES 277/24V NO CWEX YES 208/230/24V YES CW-HWX YES • Factoryinstalledelectricheat • Non-corrosivethermoplasticdrainpan,sloped for positive drainage • Separatecompartmentfordrainconnections (allows the use of PVC drain piping) • Drainpanhasfemaleprimaryand secondary fittings • Easilyaccessible1”filter • Variousoptionalfactoryinstalledvalve packages • Coilconnectionsstubouttopofunit

Optional Accessories: (see Page 3)Optional accessories include 3-Speed Wall Thermostats, Wall Panels with captive Screws (for recessed wall mounting), Condensate Overflow Switch, Closet Hanger Bracket Kit, Bot-tom Return Air Kit and various Chilled Water Valve Packages.

Accurate, Efficient, and Quiet Fan Coil Operation

(T200 shown with wall plate)

T200/T201 Thermostat Features

The new Autospeed 24V™ thermostat (part's # T200 and T201) provides 24V AC single stage temperature control of 2 pipe and 4 pipe fan coil applications. The T200/T201 thermostat offers maximum comfort and efficiency by automatically selecting the appropri-ate High, Medium, or Low fan speed, depending on room temperature and thermostat temperature setting. This automatic fan speed control not only brings the room temperature to the desired set point quickly, it maintains the room temperature with the most efficient fan speed selection. Once the desired room tempera-ture is achieved the fan coil operates on low speed for extremely quiet operation. The fan coil control board (which is factory installed in all CW units) is a circuit board that provides control of a 3-speed line voltage fan motor. The control board allows the thermostat to control the fan motor even though, by itself, the ther-mostat does not have the amperage capability nor the voltage rating capability to control the fan motor.
