Installation Guide Modbus E5000 IAQ probe

When the sealing of the duct is not possible, use a specific sealant without silicone
and VOC.
In case of use of electrical backbox, select an airtight case with sealing membrane
from which the duct passes through. If the case crosses through the sealing plane
(plasterboard), seal between the casing and panel with a special sealant without
silicone and VOC.
Connectors are specified for rigid cable 18 to 24 AWG (1 to 0.5mm dia.) or twisted 20 to 22 AWG (0.8
to 0.65mm dia.)
The connectors accept two 0.8mm cables on the same terminal in order to chain
several sensors. Beware of line losses, a 0.8mm cable has a resistance of 21Ω
per Km.
7. Installation
It is recommended to install the probe at the end of the work (after painting and using
silicone-based products).
Connect the ModBus and the 24V DC Power Supply pair cables on the terminal
block on the back of the product. Pay attention to marking: Modbus A & B and
power supply polarity.
Just push the stripped ends (flexible or rigid) into the connector. In case of a multi-
strand cable, make sure to well twist them before inserting them. In case of
difficulty, push the release tab. Respect the polarity (non-destructive).
Make sure to respect the Up marking otherwise the temperature and humidity
measurement will be jammed.
Screw the plate on the backbox.
Plug the front panel onto the plate. Pay attention to the position of the connector in
the back of the front plate.
If well mounted, the transparent window of the light sensor shall be on top middle.
8. Power supply
The power supply must be continuous (DC) and between 12 and 32V (24V nominal).
9. Power on
Few seconds after power-up, all LEDs will be activated individually for a visual
test. At the end of the cycle, failure message made of blink between orange and red
LED may appear during few seconds, the time to interrogate all sensors
Then, the blue LED shall "breathes" if the air quality is good enough.
