EE800
Room Sensor for CO2,
Temperature and Relative Humidity
The EE800 is optimized for demand controlled ventilation and
building automation in residential and commercial applications.
Versatile
The EE800 combines CO
(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 CO
which compensates for ageing effects, is highly insensitive to pollution
and offers outstanding long term stability. A multiple point CO
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.
