MODBUS-MAP
The measured values are saved as a 32 bit float 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:
1. EE-PCS Product Configuration Software (available at www.epluse.com/Configurator )
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 CO
2
, RH and T.
Important:
If deemed necessary, the CO
2
adjustment shall be made against an appropriate, accurate and certified reference. The readjustment
based on the assumption that the minimum CO
2
concentration 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 CO
2
concentration will stay higher than 400 ppm, while the concrete carbonation in new buildings can reduce the
CO
2
level way below 400 ppm.
