1 Introduction
Before you start assembling the Temperature Sensor Pro and before you take the device into
operation, please read these assembly and operating instructions carefully to the end, especially the
section referring to the safety notes.
2 Product description
With the Temperature Sensor Pro a simple monitoring of room and building temperatures is possible. The sensor
is installed in a shapely surface-mounted housing and fits very well into modern living rooms.
Due to the generous ventilation openings, the temperature sensor detects the ambient temperature very well.
An accurate temperature sensor is an important actual value transmitter for all types of radiator and heating
controls.
In combination with 1-Wire ESERA switching modules / binary outputs, a very effective and energy-saving
heating control (individual room control) is possible.
A calibration of the temperature sensor is not necessary. The Pro Temperature Sensor can be put into operation
immediately without any waiting time.
The Temperature Sensor Pro is equipped with screw terminals for the electrical connection of the 1-Wire Bus
interface and can be operated in standard mode (3-cable, for ground, 5V and data) or in parasitic mode.
Each temperature sensor has an individual serial number. The temperature sensor (DS18B20) has a high
resolution of 12 bits (0.06°C).

3 Auto-E-Connect® Support
The ESERA Auto-E-Connect® 1-Wire Plug and Play system will be used for the
1-Wire Bus supported. This enables fully automatic configurations of 1-Wire sensors
and actuators on the 1-Wire bus. It is optimized for industrial applications and
enables significant added value beyond the sensor and chip data.
The Auto-E-Connect function automatically recognizes ESERA chips, sensors and actuators, starts suitable
libraries and outputs fully formatted data.
The Auto-E-Connect functionality will be available from mid 2020 via 1-Wire Controllers, 1-Wire Gateways and
1-Wire ECO from ESERA available.
Further information on ESERA Auto-E-Connect can be found on the ESERA website, ESERA Config-Tool 3, or in
the download area for this article in the ESERA Webshop.

7 Software / Control
The device is read by 1-Wire command for DS18B20 devices. The device is supported in many
computer programs like ESERA-Station Loxone, IP-Symcon, OWFS, FHEM, (Linux) or microcontroller
applications.
8 Control by 1-Wire Controller / 1-Wire Gateway
The 1-Wire interface of the 1-Wire temperature sensor Pro is controlled by standard commands for the
device DS18B20. The 1-Wire Controller / 1-Wire Gateway has already stored a suitable formula for the
conversion of the raw data of the 1-Wire block. It is not necessary to assign an OWD number.
8.1 Data output 1-Wire Controller / 1-Wire Gateway
For the ESERA-Automation 1-Wire temperature sensor Pro, the following data are output. If you divide
the value by 100, you get the data with two decimal places.
Data output:
1_EVT|10:29:35
1_OWD1|2401=> Controller No._device No._data record|temperature (°C) example: 24,01 °C

9 Pin assignment
The 1-Wire Temperature Sensor Pro is supplied with screw terminals. The pin assignment is printed on
the printed circuit board.
In normal mode the sensor must be supplied with three cables, ground, 1-Wire Data and 5V.
In parasitic mode the sensor is only connected with ground and 1-Wire Data. Additionally, a connection
between 5V and ground must be established at the sensor.
Note: Basics and further information referring to the 1-Wire Bus system can be found in our eBook,
available for purchase in our webshop https://www.esera.de/service-support/dokumentation/.
10 Assembly
The location of the assembly must be protected against humidity. The device may be used only in dry
inside spaces and protected outside areas. Ensure that the installation is free of draughts. The device
is designed to be assembled as a fixed device within a switchboard.
11 1-Wire Network
No special requirements are needed on the cable used for short connection lengths. With unshielded cable, a
wider connection length can be achieved in an undisturbed environment, as the capacitive bus load is lower. A
total length of 60 m and more can be easily achieved with no additional measures.
In a disturbed environment, the cable should be shielded in order to improve the system’s sensitivity to
interference. The higher capacitive load reduces the maximum possible connection length.
The special thing about the wiring of the sensors is the “BUS technology”: All sensors are operated in parallel on
a three-core cable, which is used for both power supply and data communication.
12 Measuring accuracy
The sensors are calibrated during manufacture and have a typical measurement accuracy of ±0.5°
at 23°C operating temperature. The accuracy is reduced in addition to the upper and lower measuring
range limits. Further information can be found in the DS18B20 data sheet on our website.
13 Operating conditions
The sensor is designed to measure the temperature of gases. The Maxim temperature sensors are
semiconductor sensors. The unhoused sensors are designed for temperature measurements in the range of
-55 ... +125 °C. These temperature values stated under technical data are limit data for the entire
1-Wire Temperature Sensor Pro and must not be exceeded, otherwise the sensor may be damaged.
14 Disposal note
Do not dispose of the device in household waste! Electronic devices must be disposed of in
accordance with the directive on waste electrical and electronic equipment via the local
collection points for waste electronic equipment!
15 Safety instructions

observed, especially VDE 0100, VDE 0550/0551, VDE 0700, VDE 0711 and VDE 0860
All final or wiring work must be carried out with the power turned off.
Before opening the device, always unplug or make sure that the unit is disconnected from the mains.
Components, modules or devices may only be put into service if they are mounted in a contact proof housing.
During installation they must not have power applied.
Tools may only be used on devices, components or assemblies when it is certain that the devices are disconnected
from the power supply and electrical charges stored in the components inside the device have been discharged.
Live cables or wires to which the device or an assembly is connected, must always be tested for insulation faults or
breaks.
If an error is detected in the supply line, the device must be immediately taken out of operation until the faulty cable
has been replaced.

When using components or modules it is absolutely necessary to comply with the requirements set out in the
accompanying description specifications for electrical quantities.
If the available description is not clear to the non-commercial end-user what the applicable electrical characteristics
for a part or assembly are, how to connect an external circuit, which external components or additional devices can
be connected or which values these external components may have, a qualified electrician must be consulted.
It must be examined generally before the commissioning of a device, whether this device or module is basically
suitable for the application in which it is to be used.
In case of doubt, consultation with experts or the manufacturer of the components used is absolutely necessary.
For operational and connection errors outside of our control, we assume no liability of any kind for any resulting
damage.
Kits should be returned without their housing when not functional with an exact error description and the
accompanying instructions. Without an error description it is not possible to repair. For time-consuming assembly or
disassembly of cases charges will be invoiced.
During installation and handling of components which later have mains potential on their parts, the relevant VDE
regulations must be observed.
Devices that are to be operated at a voltage greater than 35 VDC / 12mA, may only be connected by a qualified
electrician and put into operation.
Commissioning may only be realized if the circuit is built into a contact proof housing.
If measurements with an open housing are unavoidable, for safety reasons an isolating transformer must be
installed upstream or a suitable power supply can be used.
After installing the required tests according to DGUV / regulation 3 (German statutory accident insurance
https://en.wikipedia.org/wiki/German_Statutory_Accident_Insurance) must be carried out.
