E+E Elektronik EE800 User manual

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 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 CO2sensor, 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 CO2, T and RH or Td
• Two analogue outputs (0 - 5 V, 0 - 10 V or 4 - 20 mA ) for CO2and 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.
CO2Sensing 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 CO2sensing 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.

USER GUIDE
EE800 - HVAC Room Sensor for CO2, Temperature and Relative Humidity

DIMENSIONS / MOUNTING
The electronics is located in the front cover, which can be easily snapped on/off once the back cover is fixed onto the wall (D = moun-
ting 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.

MODBUS AND BACNET
HARDWARE
• The bus termination shall be realized with 120 Ohm resistor by using the switch on the board.
• Very important:
For proper function the power supply must be strong enough to ensure supply voltage within the specified range (see technical
data) at any time and at all devices in the bus. This is particularly relevant when using long and thin cables which can cause high
voltage drop; please note that a single EE800 draws a peak current of 150 mA.

Address setting via EE-PCS Product Conguration Software:
All switches at position 0 → address has to be set via conguration software
(factory setting: 241...Modbus / 3...BACnet).
Example: Address is set via conguration software.

Address setting via DIP switch:
Setting the DIP switch to any other address than 0 overwrites the address
set via conguration software.
Example: Address set to 11 (=00001011 binary).
BACNET INFOS
Please see PICS (Product Implementation Conformance Statement) - available at www.epluse.com/EE800)

MODBUS-MAP
The measured values are saved as a 32 bit oat value from 0x19 to 0x2F.
The factory setting for the Modbus address is 241 as an integer 16 bit value. This address can be customised in the register
60001 (0x00) (value margin 1 - 247 permitted).
The serial number as ASCII-code is located at register address 30001-30008.
The firmware version is located at register address 30009.
The required units (metric or non-metric) must be selected according to the „ordering guide“, see EE800 data sheet.

Depending on the protocol, Modbus or BACnet, the address, baudrate, parity and stop bits can be set via:

2. Modbus protocol, refer to Modbus Application Note (available at www.epluse.com/EE800)
SETUP AND ADJUSTMENT
The EE800 room sensor is ready to use and does not require any configuration
by the user. The factory setup of EE800 corresponds to the type number
ordered. For ordering guide please see data sheet at www.epluse.com/EE800.
If needed, the user can change the factory setup by using the optional
Configuration Adapter Cable HA011066 and the EE-PCS Product
Configuration Software.
The user can assign physical quantities to the analogue outputs, set the
scaling of the outputs, change the display settings and perform one or two
point adjustment for CO2, RH and T.
Important:
If deemed necessary, the CO2adjustment shall be made against an appropriate, accurate and certified reference. The readjustment
based on the assumption that the minimum CO2concentration of the environment air is 400 ppm (the principle of the so-called auto-
matic background calibration ABC) may relevantly depreciate the device performance. In continuously occupied buildings like hospi-
tals, the minimum CO2concentration will stay higher than 400 ppm, while the concrete carbonation in new buildings can reduce the
CO2level way below 400 ppm.
