This probe is used to control the mechanical air renewal in buildings. The new thermal standards impose airtight buildings and a mechanically controlled renewal. E4000 probe ensures optimum control of ventilation.
A regulation in function of human expiration of CO2 (meeting rooms, offices) and air quality (VOC, formaldehyde, some toxic compounds or odorants) can result in considerable energy savings.
Thanks to its temperature sensor, the E4000 probe controls the heating and cooling with a self-adaptive PID. This control can be done on perceived temperature.
The NanoSense E4000 probe uses only solid state sensors (NDIR optional) that require no maintenance. This technology provides cost competitive sensors and a lifetime of over 10 years without any maintenance. Furthermore consumption is much lower than NDIR.
CO2 and VOCs sensor modules are interchangeable without recalibration that allows to change the sensors every 10 years keeping the motherboard without re-setting.
Sober and discreet design of the probe can be integrated easily either in refurbished buildings or new ones.
The variety of interfaces and power supply allows the probe to interface with most existing systems.
A modular architecture for high flexibility
Communication cards allow modular interfaces with the most common building automation or industrial bus systems as the RS485 Modbus (ASCII or RTU), the Konnex (KNX) LON, POE (IP) and EnOcean wireless systems.
By combining two modular cards like EnOcean and KNX, we obtain a complementary gateway function (10 sensors and 5 actuators compatible with all available units on the market)
The EnOcean Alliance technology is based on wireless technology and energy harvesting solutions for wireless, batteryless and maintenance free sensors (mini solar cells). More than 300 companies are members of the EnOcean Alliance. Interoperability between different manufacturers of these products allows a quick installation and low maintenance of devices with the probe (no batteries to change). To avoid the use of repeaters and reduce installation constraints related to radio propagation from one room to another, it is recommended to use a EnOcean gateway for each E4000 probe and therefore for each room rather than a single gateway for several rooms, especially as management via KNX address of each E4000 probe is simplified. Therefore EnOcean sensors and actuators become easily identified by their KNX address.
E4000 probe can be equipped with an optional EnOcean radio link (http://www.enocean-alliance.org) for integrating up to 10 sensors and 5 actuators such as:
- Switch (ON / OFF, UP / DOWN, position setting) for lighting, shutters, blinds …
- Occupancy and brightness sensor (ceiling mount) for lighting management.
- Contact opening probe or handle for window or door.
- Room thermostat and settings (day, night, frost)
- Remote adjustment and control (lighting, shutter)
- Actuator for lighting, shutters, blinds …
Telegrams received from any wireless EnOcean device are interpreted by the E4000, and data converted into KNX or LON or IP communication objects.
Power Over Ethernet
PoE (Power Over Ethernet) allows you to power supply Ethernet devices (such as access points, IP cameras, IP phones, switches ...) using the network cable. Ethernet cable category 5/5E or 6 carries both data and power without the risk of short circuit or alteration of data. The power supply is provided only at the PoE detection equipment and is ended when the equipment is disconnected. The IEEE802.3af standard defines the implementation of this technology ensures compatibility and interoperability of equipment complying with this standard.

KNX | LonWorks
KNX and LonWorks protocols are based on the BUS principle. Explanation: the principle of the bus is that all project participants (buttons, actuators ...) interact with each other using the bus. The system programming is done with the KNX software ETS or LonMaker for a LonWorks system, it is possible to modify the program, for example a button lights another lighting circuit rather than the current one. The more complex features an installation or building automation has, the better the KNX technology can be adapted compared to a traditional solution. Indeed, the existence of a communication network through the bus allows the realization of complex commands. Communication protocols KNX and LonWorks can intelligently manage your heating and lighting to ensure energy savings over the mid-term.
- Saving considerable time for installing the electrical cable
- Only power circuits are brought to the electrical panel
- The possibilities of extensions are possible without major work
KNX and LON databases of the E4000 probe manage annex probes. The EnOcean module transmits information from RS485 annex probes.
Annex probes working with E4000 probe:
- PM10, PM2.5 and PM1 particles annex probe
- Radon annex probe (regulated in 31 departments in France, radon responsible for 2000-6000 deaths per year)
- Ozone annex probe (ozone mainly generated by laser printers and photocopiers)
