Product Specification

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.
