PRODUCT DESCRIPTION
The FCMFX-R series are intelligent sensors featuring adjustable
temperature, relative humidity and CO
2
ranges. Their algorithm controls
a single analogue / modulating output based on the measured T, rH
and CO
2
values, which can be used to directly control an EC fan or an
actuator powered damper. All parameters are accessible via Modbus RTU.
