USER’S GUIDE
EE10 – HVAC Room Transmitter for Relative Humidity and Temperature with digital RS485 interface

GENERAL

EE10 combines relative humidity (RH) and temperature (T) measurement in one device with modern design. The RH and T measured data is available either on a BACnet or Modbus RTU interface. Additionally, it calculates the dewpoint temperature (Td), absolute humidity (dv), mixing ratio (r), enthalpy (h), frost point temperature (Tf) and water vapor partial pressure (e).

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.

DIMENSIONS / MLUNTING

The electronic of EE10 is 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.

EU version

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 EE10 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 EE10 enclosure.

MODBUS AND BACNET

HARDWARE

The bus termination shall be realized with 120 Ohm resistor, 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.

**ADDRESS SETTINGS

Slave address setting via EE-PCS Product Configuration Software:**
All switches at position 0 address has to be set via configuration software (factory setting: 236…Modbus / 5…BACnet). Example: Slave address is set via configuration software.

**ADDRESS SWITCH

Slave address setting via Dip-switch:**
Setting the Dip-Switch to any other address than 0 overwrites the slave address set via configuration software. Example: Slave address set to 11 (=00001011 binary).

BACNET INFOS
Please see pics (product implementation conformance statement) Communication factory setting:
Baud rate: 38400 Data bit: 8 Parity: no Stop bit: 1

MODBUS-MAP
Communication factory setting:
Baud rate: 9600 Data bit: 8 Parity: even Stop bit: 1

The factory setting for the Slave-ID is 236 as an integer 16Bit value. This ID can be customized 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 measured values are saved as a 32Bit float value from 0x19 to 0x2F. The required units (metric or non-metric) must be selected in the ,,Ordering guide”, see EE10 data sheet.

The EE10 transmitter is ready to use and does not require any configuration by the user. The factory setup of EE10 corresponds to the type number ordered. For ordering guide please see data sheet at www.epluse.com/ee10.
If need, the user can change the factory setup by using the optional Configuration Adapter Cable HA011066 and the E+E Product Configuration Software (EE-PCS).

Configuration Adapter Cable HA011066

The user can change the display settings and perform one or two point adjustment for RH and T.
The free E+E Product Configuration Software (EE-PCS) and can be downloaded from www.epluse.com/configurator.
