Production Description:

The EE800 is optimized for demand controlled ventilation and building automation in residential and commercial applications.
 
Versatile
The EE800 combines CO₂, temperature (T) and relative humidity (RH) measurement in one device with modern design. Additionally, it calculates the dew point temperature (Td).
 
Outstanding Measurement Performance
The EE800 incorporates the E+E dual wavelength NDIR CO₂ sensor, which compensates for ageing effects, is highly insensitive to pollution and offers outstanding long term stability. A multiple point CO₂ and T factory adjustment procedure leads to excellent CO₂ measurement accuracy over the entire T working range.
 
Analogue and Passive Outputs, Digital interface, Display
EE800 with analogue outputs features an optional passive T sensor, while at EE800 with RS485 additional physical quantities are available on the Modbus RTU and BACnet MS/TP interface:absolute humidity, mixing ratio, enthalpy, frost point temperature and water vapor partial pressure.
 
Easy Installation and Maintenance
The EE800 enclosure is available in several colours and in two sizes according to regional standards. The snap-on design facilitates the replacement of the active front part within seconds
while the wiring remains intact. Furthermore, it makes possible to wire the device without exposing the electronics to construction site pollution.
 
Configurable and Adjustable
An optional USB configuration adapter and the free EE-PCS Product Configuration Software facilitate easy setup and adjustment of EE800.
