FAN COIL UNIT CONTROLS
Analog Fan Coil Unit Controller
MODEL: CEE-5201
The Engineered Comfort CEE-5201 controller is mounted
inside the controls enclosure on the fan coil unit and is factory
wired. Engineered Comfort fan coil units with analog controls
provide extremely accurate variable air volume control. They
are factory calibrated for each unit permitting quick and easy
start-up with no field settings required, but may be simply and
easily field adjusted if necessary to suit changing
requirements.
Control Parameters:
• Maximum fan cooling airflow.
• Minimum fan cooling airflow.
• Modulating Chilled Water Valve Actuator.
• Stage 1 Heating with aux. fan airflow setting (on / off hot
water valve or one stage electric heat).
• Stage 2 Heating with aux. fan airflow setting (on / off hot
water valve or two stage electric heat).
Five potentiometers on the controller permit simple
adjustment of flow settings with a 0 – 10 Vdc voltmeter. Meter
taps are provided. A calibration chart is provided inside the
controls enclosure for each unit.
