Function
This duct transmitter is used for temperature and humidity
measurements in air. The measurements received can be used to control
ventilation with high precision and improve the air quality in for
example residential and office areas. By increasing the air exchange only
when it is necessary, it is possible to minimise energy costs.

Installation
– Find a location in the duct where the transmitter can be expected to
give a representative reading. It should be placed at least 4 duct
diameters from a bend or other obstacle, e.g. a damper, for minimal
turbulence.
– Use a 13 mm drill bit to make a hole in the duct
– Remove the 4 screws in the cover to access the terminals
– Place the transmitter in the duct
– Connect the wires to the terminals according to the wiring diagram
under
– Screw the cover back on and ensure that it is properly fastened and
that the cable gland makes a tight seal around the cable
N
Noottee!! If there is a risk for condensation in the probe, mount the transmit-
ter upright.
