GENERAL
EE800 combines CO
2
, temperature (T) and relative humidity (RH) measurement in one device with modern design. Additionally, it
calculates the dewpoint temperature (Td). EE800 features analogue outputs or digital RS485 interface. At the EE800 with RS485
additional physical quantities are available via Modbus RTU or BACnet MS/TP: absolute humidity (dv), mixing ratio (r), enthalpy (h),
frost point temperature (Tf) and water vapor partial pressure (e).
The EE800 incorporates the E+E dual wavelength NDIR CO
2
sensor, which compensates for ageing effects, is highly insensitive to
pollution and offers outstanding long term stability.
EE800 is available with:
• Three voltage outputs (0 - 5 V or 0 - 10 V) for CO
2
, T and RH or Td
• Two analogue outputs (0 - 5 V, 0 - 10 V or 4 - 20 mA ) for CO
2
and T
• 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.

Sensing Cell
•
The wiring shall be positioned so that they do not impact with the sensing cell. Failure to comply with this may lead to relevant
measurement errors.
•
EE800 features a protection cap for the CO
2
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.
