General
The IAQ-sensor product eSENSE Duct (for mounting in ventilation ducts) is designed
to measure carbon dioxide (CO
measurements by the resistive temperature probe mounted by the user. Option -Disp
displays the measured CO
The units are designed for connecting to Direct Digital Control (DDC) with 0-10V or
2-10V signal inputs. The two parallel signal outputs Out(1) (0-10V) and Out(2) (2-10V
or 4-20 mA) give linear signal voltages or currents corresponding to the measuring
range.
The output Out(2) also indicates the status by setting the output voltage to 1V or the
output current to 2 mA when the sensor self-diagnostics detects any error.

For correct function it is indispensable that the sealing of the box cover, the cable entry bushings, the cable feed through and the duct entrance are absolutely tight.
