Using remote control / Modbus configuration, you can activate (or deactivate) a channel, change the measuring
range, set the set points and time-delay...
Principle: the configuration options are accessed via folders and sub-folders (similar to Windows ).Access is
made via a numerical code (full details in this manual).

The on-off switch is located on the left of the terminal block for
transmitters with a 24 Vac/dc power supply model and on the right
of the relay 1 and 2 for transmitters with a 230 Vac power supply
model (Ref.HV). With the on-off switch you can choose analogue
output 0-10V (voltage) or 4-20 mA (current).

It's extremely unwise to remove the protection tip of our hygrometry
probes as the sensitive element is very fragile even to light contacts.
However, if you have to remove the protection tip, take all possible
precautions and avoid any contact with the sensitive element.
To remove the protection tip, unscrew it or unclip it.

3. Activation code and access to functions
!
This step is COMPULSORY for each configuration.
To access the transmitter functions, and for safety, you have to first enter a safety code.
• Please check that the transmitter is powered on.
• If the transmitter displays an error code, please see “Errors Code” section on page 31
Step 1
Press on
to get this screen
Enter the CODE “0101”
with the keypad and
validate with
Step 2 The code must be entered from left to right.
To increment a value or a level, press
To decrement a value or a level, press
To validate a value (level) or to validate the code, press
To return to the previous status or to cancel, press
The first “0” blinks, which means that this column is activated and you can
enter data from the keypad.
This screen appears:
Step 3
This screen confirms that the code was correctly entered, and that you can
configure the transmitter.
If the code was wrongly entered, the transmitter initializes and returns to the
starting display.
Configuration folder number
The transmitter includes 6 folders maximum :
• 100 • 400
• 200 • 500
• 300 • 600
Configuration folder
selection
Step 4 To select your configuration folder, press to increment 100 or press to
decrement 100.
Once the folder is selected, press to validate.
L
On the top left of each page of this manual, you can find a reminder of the
configuration folder where the function is available.
F400
Ex. In the folder 400, you can configure the alarms
and relays. See page 12.

4.a - Transmitter channel for infrared remote control
You can change the channel number for receiving the signal from the infrared remote control.
The advantage is that only one remote control is required to drive several transmitters, and that
there is no interference if 2 transmitters are located side by side.
Step Go into the configuration mode (see page 5). The folder number displayed
corresponds to the last configuration folder used.
Select the folder “100” and validate with .

Step
Select the sub-folder “100” and validate with .
The cursor >goes to the line of available choices.

Step With and keys, select the channel number (from 00 to 09).
Validate with .
4
Step The cursor >returns to sub-folders line.
• press twice to return to reading mode
• press once to select another folder.
• with and keys, you can choose another sub-folder from the folder 100.

Select the folder “100” and validate with .
Select the sub-folder “103” and validate with .
The cursor >goes to available choices.
With and keys, set the slave addressing number (from 1 to255).
Validate with .
The cursor >goes to sub-folders line.
• press twice to return to reading mode.
• press once to return to another folder selection.
• with and keys to choose another sub-folder from the folder 100.
