Digital transmitter for humidity & temperature:
Wall Version
Congratulations on your purchase of the new state-of-the-art HygroFlex3-series transmitter.
Please read these short instructions carefully before installing the device.
General description
The HygroFlex3-series devices are universal transmitters for transmission of humidity and
temperature measurements. These short instructions are limited to a description of the main
functions and installation of the device. The detailed instruction manual can be found on

Caution:
In order to get correct measurement values, the sensor must be instaled in a way
that the air fl ows around the sensor.
1. Remove the montage plate by drilling out the screws.
2. Mount the mounting plate to the wall by using 2 or 4 screws.

Programming
The basic settings of the devices are made in the factory according to your order. The transmit-
ters are adjusted in the factory and therefore do not need to be checked and readjusted during
installation. The devices can be started immediately after installation.
Display
In models with LC display the value can be read directly.
Trend indicators Humidity-, dew point- or frost point value.
Depends on the ordered version.
Temperature value

Scaling / Adjustment / Firmware update
The following settings can be made with the help of the HW4 software and either the service
cable AC3006 or AC3009:
• new scaling of the outputs
• adjustment
• fi rmware update
