Settings and use of the transmitter To configure the transmitter, it must not be energized. Then you can make the required settings thanks to the DIP switches as shown on the drawing below. When the transmitter is configured, you can power it up. To configure the transmitter, unscrew the 4 screws of the housing then open it. DIP switches allowing the different settings are accessible. Active switch On-off switch ■ □ Setting of output Setting of measuring range Off On Measuring range setting To set a measuring range, put the on-off switches 2, 3 and 4 as shown below: Measuring ranges...

Mounting To mount the transmitter, mount the ABS plate on the wall (drilling: 06 mm, screws and pins are supplied). Insert the transmitter on the fixing plate (see A on the drawing beside). Rotate the housing in clockwise direction until you hear a "click" which confirms that the transmitter is correctly installed. Ambient model has not any fixing plate. 4 fixing holes are inside the back housing. Use them to install the transmitter on the required location. Positioning of the probe For duct model For duct models, the positioning of the probe is important to get accurate measurements: the...
