1. INTRODUCTION
This document presents the installation and maintenance schemes
for Occupancy sensor with Hub 8 SE: exhaust compensation valve
and third-party Modbus system. First, we will focus on the S-PRE/
DAY-NIGHT/T Modbus sensor's connections with Hub 8 SE and
secondly with third party Modbus systems.

2. DESCRIPTION
2.1. GENERAL INFORMATION
Protocol: Modbus RTU / through RS485
Baud rate: 9600 bit/s
Modbus implementation class: basic
Connectors type: RJ45 with shielded CAT5E cable or better
The detection principle of the S-PRE/Day*-Night**/T Modbus sensor is
based on infrared rays absorption. This method allows a very high fidelity
of response and is independent of any other variable (such as moisture,
dust, etc.).
The connection to the system is made through RJ45 connectors.
The S-PRE/DAY*-NIGHT**/T optical sensor is composed of:
- A Fresnel lens with 31 pairs of facets that concentrate the radiation
emitted by a person on pyroelectric sensors and cut the detection field
into 62 zones
- Specific pyroelectric sensors that collect radiation infrared emitted by a
person and detects mouvements through the factes of the Fresnel lens
the number of movements through the facets of the Fresnel lens
The detector includes a Red LED indicator that displays the detections in
order to inform the users. When luminosity in the room is very low, the
LED is automatically switched off.
