E+E Elektronik EE10 User Manual

GENERAL
EE10 combines relative humidity (RH) and temperature (T) measurement in one device with modern design. The RH and T mea-
sured 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 / MOUNTING
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.

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.

Summary

General Product Overview

Product Capabilities

EE10 measures RH and T, calculating dewpoint, absolute humidity, mixing ratio, enthalpy, frost point, and water vapor partial pressure via RS485.

Safety and Handling Precautions

Operational Safety

Avoid extreme stress, not for critical safety applications. Handle electronics ESD sensitively. Allow 5 min warm-up.

Dimensions and Mounting

Enclosure Opening

Press latch A to open the enclosure using a screwdriver or pen. The electronics are in the front cover.

Enclosure Closing

Set front cover into flute B, rotate, and press latch A until it snaps closed.

Mounting Recommendations

Snap cover after construction. Tighten conduit box to prevent false air ingress for accurate measurements.

Connection and Communication

Digital Interface Wiring

Connect on electronics board using screw terminals for daisy-chain wiring, use 120 Ohm termination resistor.

Modbus and Bacnet Settings

Set slave address via EE-PCS Software or Dip-Switch. Factory settings: 236 (Modbus), 5 (BACnet).

Modbus Register Map

Details on reading serial number, firmware, measured values, and writing Slave-ID and protocol settings.

Technical Specifications

Measured Values and Accuracy
