USER‘S GUIDE
EE800 - HVAC Room Transmitter for CO2, Temperature and Relative Humidity
GENERAL
EE800 combines CO2, temperature (T) and relative humidity (RH) measurement in one device with modern design. Additionally, it
calculates the dewpoint temperature (Td). 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 (dv), mixing
ratio (r), enthalpy (h), frost point temperature (Tf) and water vapor partial pressure (e).
It incorporates the E+E dual wavelength NDIR CO
and offers outstanding long term stability.
EE800 is available with:
• Three voltage outputs (0-5 V or 0-10 V) for CO
• Two analogue outputs (0-5 V, 0-10 V or 4-20 mA ) for CO
• Modbus RTU or BACnet MS/TP interface, where all physical quantities, as above, are available according to the model ordered.

CAUTION
• The device shall not be exposed to extreme mechanical or thermal stress.
• This device is not appropriate for safety, emergency stop or other critical applications where device malfunction or failure could
cause injury to human beings.
• The electronics board is an ESD sensitive device, please handle it accordingly and avoid touching it during installation.
• Please allow min. 5 minutes warm up time for the device to reach the specified measurement performance.
• The sensing cell shall not be exposed to any mechanical stress.
CO2 Sensing Cell
• The connecting cable or wires shall be positioned so that they do not impact with the sensing cell. Failure to comply with this
may lead to relevant measurement errors.
• The latest generation of EE800 (after August 2017) features a protection cap for the CO2 sensing cell. Although this facilitates
the handling during installation and diminishes the chances of unintended mechanical impact onto the cell, please observe the
wiring guidelines as above. Do not attempt to remove the protection cap.

The electronics of EE800 are located in the front cover, which can be easily snapped on/off once the back cover is fixed onto the wall
(D = mounting holes) and wired.
OPENING THE ENCLOSURE
Press to release the latch A till the enclosure can be opened. Use a
screwdriver or a pen.
CLOSING THE ENCLOSURE
Set the front cover into flute B, rotate it like C and press it onto the
back cover till the latch A snaps in.
IMPORTANT
In order to protect the front cover and the electronics from typical
construction site pollution (such as painting of the walls) the front cover
should be snapped on only after the construction works are completed.
As EE800 is generally mounted onto a conduit box, for accurate
measurement results it is important to tighten the conduit box for
avoiding false air ingress (along the electrical tubes inside the wall)
into the EE800 enclosure.
