1. What is b@home?
The b@home system – the intelligent remote control for heating and cooling
Use the b@home system from alre to control and monitor your heating and cooling at any time and from any location.
Smartphone/tablet app or web browser – the intuitively simple control allows you to access the rooms individually or all
together. And remote control of the b@home system is incredibly simple too: If you are out and about, you can use the
Internet for mobile access but if you are at home, you can simply use your home network.
The b@home gate is the central component of the b@home system and the interface between the alre wireless system
and WLAN/LAN router. Existing alre wireless systems can also be retrofitted. The optional b@home control unit provides
central access to the settings of all channels and/or heating/cooling zones. It can be used as a central control unit or as a
room control unit and works with all common switch ranges.
Control and monitor your
heating/cooling system in your home
network via your LAN/WLAN (no
Internet connection needed)
Control and monitor your
heating/cooling system at any time
and from any location via the Internet
Even without an Internet connection, the
b@home system can be conveniently
operated and programmed in the home
network using an appropriate end device
(app). The data and configuration
parameters are simply stored locally in
the b@home gate. The system can also
be controlled at any time independently
of your smartphone or tablet with the
b@home control unit.ooling system in your
home network via your LAN/WLAN (no Internet
Once you have registered on the
b@home portal, the b@home system
can be operated and programmed at any
time and from any location via the
Internet. And even if the Internet
connection is lost, the control function is
retained. Operation via the home network
is therefore still possible.

7. How the b@home system works
The b@home gate can be used to control, monitor or reprogram the alre wireless heating/cooling system at any time and
from any location. The b@home gate is the interface between the alre wireless system and your router. This allows both
new alre wireless systems needing to be set up and existing systems to be controlled via the Internet or home network. The
system is operated using the b@home app (iOS/Android) or b@home portal via a web browser on a notebook/PC. A minimal
system with the b@home gate must include at least one sensor (transmitter or wireless room temperature sensor) and one
actuator (receiver or wireless room temperature controller) and a router with a free Ethernet port (LAN). One b@home gate
can be used to monitor and control up to 32 rooms and/or heating/cooling zones. If necessary, more b@home gates can
be operated in the same network (see Section 14.2).

11. Mounting location
The b@home gate has been developed so that all connected actuators and sensors can be reached in your home or
apartment. In exceptional circumstances, faults and excessive distances may result in outages.
The mounting location should be selected so that all devices to be connected with the b@home gate can be reached. A
site located centrally with regard to where these devices are installed is best for the b@home gate.
Generally speaking, the transmission and receipt characteristics of the b@home components are highly dependent on
spatial circumstances. For example, the range is reduced by e.g. reinforced walls, ceilings, metal housings, flooring/coatings
containing metal etc. You will find more information about this under Section 16.
12. Mounting
The gate is either surface-mounted or wall-mounted using the equipment pack enclosed, comprising 2 screws and dowels.

13. Router/power supply connection
Ensure the Ethernet cable and power supply are connected in the right order (see information below).
Only use the wall power supply included in the scope of delivery.
If several b@home gates are to be operated in the same network, it is essential that the devices are connected
with the network and set up one after another. For more information about this, go to Section 14.2.
Step 1: Use Ethernet cable to connect b@home gate to a free LAN port on the router.
Step 2: Use wall power supply to connect b@home gate’s power supply. Once the power supply is connected, the two
lamps light up green for a short time. As soon as the lamps go out, the b@home gate is ready and the system
can be set up.
14. Setting up system
After the b@home gate has been connected as described under Section 13, the b@home gate is ready for operation (both
lamps off) and the system can be set up.
14.1 User interfaces
Some of the settings listed below can be undertaken using the b@home app, the configuration interface of the b@home
gate or the b@home portal. These symbols show which settings can be undertaken via the respective user interfaces:
For reasons of security, Internet access can only be set up and the network name can only be changed via the
b@home gate’s configuration interface. We recommend using the b@home app for all other steps needed to set
up the system.
14.1.1 b@home gate configuration interface
Enter http://bathomegate/ in the browser address line of one of the devices in your home network
and press the Enter key - the b@home gate in your home network is displayed. Now follow the on-
screen instructions.
For security reasons, authentication is required each time you access the system (see on-screen instructions). You
will be automatically logged off 10 minutes after your last input and you will then need to authenticate yourself
again.
If you are operating several b@home gates in the same network, rather than http://bathomegate/ enter the
destination address you have changed (see Section 14.2).
Alternatively, you can also enter the IP address of the b@home gate in the browser address line of one of the
devices in the home network. If you are not using a Windows network, in some cases this may be absolutely
necessary. You can use the b@home app installed on the mobile end device logged onto the home network to find

the IP address of the b@home gate.
If you are not able to establish a connection to the b@home gate, check the network connection and the settings
of your router (also see Section 6. System requirements).
14.1.2 b@home app
The b@home app is available for free from the App Store (iOS 7.0 or higher) or Google Play Store
(Android 2.2 or higher).
For security reasons, the mobile end device has to be authenticated. This is a one-off process (see on-screen
instructions).
If you are not able to establish a connection to the b@home gate, check your network connection and/or the settings
of your router (also see Section 6. System requirements).
14.1.3 b@home portal
Once you have set up Internet access via the b@home gate’s configuration interface (see 14.9),
you can go to https://www.klimaregler.de on the b@home portal to undertake settings on your
system.
14.2 Name in network (host name)
If you are using just one b@home gate in your network, no changes are needed.
If further b@home gates are to be operated in the same network, before starting up another b@home gate, you need to
change the destination address http://bathomegate/ (e.g. into http://bathomegate1/) because the same destination
addresses are not permitted in a network.
14.3 System functions
State the functions your temperature control system can perform:
•heating
•cooling
•heating and cooling
These settings depend on the type of temperature control system and the actuators (receivers) used. An incorrect
selection may result in damage to the system and increased energy consumption.
14.4 Designation of the b@home gate
Any name can be entered and is displayed in the b@home app and b@home portal.

14.5 Date and time settings
The date and time should be taken from the system time of the computer/end device. An automatic changeover between
summer and winter time can also be activated here.
Automatic changeover between summer and winter time: standard summer time in the European Union runs from 2 am
CET on the last Sunday of March until 3 am CEST on the last Sunday of October (Directive 2000/84/EC of the European
Parliament and Council). The time of the b@home gate changes automatically on these dates. The automatic changeover
between summer and winter time can be deactivated for time changes on other dates or in regions without daylight saving
time.
14.6 Setting up rooms
If retrofitting in existing alre wireless systems, all receiver channels must be deleted before the actuators are trained.
Information about how to do this can be found in the respective actuator operating instructions
14.6.1 Room name
The room name entered is also displayed in the b@home app, b@home portal and b@home control unit. Identical room
names can be entered but this is not recommended.
Special characters entered here may be displayed differently in the b@home control unit.
14.6.2 Training sensor (wireless room temperature sensor/transmitter)
At least one sensor should be trained for each room. Once you have pressed the “Train sensor” button, the training function
must be triggered on the sensor within 15 seconds. To do this with FTRFB-280.1xx sensors, briefly press the training button
once. With the FTRFB-280.101 sensor, the training button can only be pressed when the housing is open.
More information about the training function for the sensors can be found in the relevant operating instructions.

003
Wireless room temperature sensor with
setpoint adjuster and
comfort mode/energy-saving mode
operating mode switch
12)
020 b@home control unit 12) / 3)
1) When training more than one sensor of this type per room and/or when also training for the 002, 003 or 020 function
types, an average value is calculated from the individual room temperature measurements (e.g. for large rooms).
2) Only one sensor of the 002, 003 or 020 function type can be trained. If a second sensor of this function type is trained,
the previous one is deleted. The last trained sensor applies.
3) No more than 16 b@home control units (020 function type) in total may be operated on one b@home gate.
If using sensors with a setpoint adjuster (002 and 003 function types), the setpoint which can be adjusted on the
sensor cannot be changed as standard with the b@home app, b@home portal or b@home control unit. You can
activate adjustment of the setpoint in the b@home app and the settings in the b@home app, b@home portal or
b@home control unit then apply.
The operating mode switch for sensors of the 003 function type does not work in the b@home system.
14.6.2.1 Central control unit
One central FTRCUd-210.021 b@home control unit can be trained on the b@home gate. If a second, central control unit
is trained, the previous device is deleted. The last trained device of the same type applies.
As the central control unit, the FTRCUd-210.021 provides access for central influence over the b@home gate. Depending
on the setting on FTRCUd-210.021, this can be used as a potential-free “ECO”, “Standby” (frost protection),
“Heating/cooling changeover” contact input and/or as an “Upstream sensor” or “Dew point sensor” sensor input. Any change
to the status on the input affects all rooms.
If no b@home control unit is used, no settings are needed here.
More information about the b@home control unit can be found in the corresponding operating instructions.

14.6.3 Cancelling sensor (wireless room temperature sensor/transmitter)
Press the “Cancel sensor” button. Within 15 seconds, the training button on the sensor (001, 002, 003 or 004 function types)
now has to be pressed and/or the cancel function (020 function type) has to be started. Alternatively, you can select the
desired sensor on the configuration interface of the b@home gate and thereby cancel off.
If sensors are cancelled, note that if there are no longer any transmitters trained with the 001, 002, 003 or 020
function type, a trained actuator will shift to emergency mode. More information about emergency mode can be
found in the respective actuator operating instructions.

14.6.4 Training actuator (wireless room temperature controller/receiver)
At least one actuator should be trained for each room. Once you have pressed the “Train actuator” button, the training
function must be triggered on the actuator within 15 seconds. To do this, briefly press the training button once. If using
multi-channel actuators, the corresponding channel must first be selected with the channel selection button. Any
combinations and quantities of actuators can be trained per room.
More information about training actuators can be found in the respective actuator operating instructions.
Trained sensors are displayed in the b@home app, b@home portal or on the user interface (HTML page) of the
b@home gate - while actuators are not.
Possible manual settings on actuators, such as central control or exclusion of channels from cooling mode, must
be reset to the factory settings before training.
14.6.5 Cancelling actuator (wireless room temperature controller/receiver)
To cancel, press and hold the actuator’s training button until the lamp lights up red permanently after around 10 seconds.
The lamp of the deleted channel lights up red permanently to indicate that the entire receive channel has been successfully
deleted. Control is now deactivated.
If using multi-channel actuators, the corresponding channel must first be selected with the channel selection button.
More information about cancelling actuators (deleting entire receive channel) can be found in the respective
actuator operating instructions.
14.6.6 Connection test
Pressing the “Connection test” button allows the correct wireless connection between b@home gate and actuators to be
tested. If the connection is correct, the lamp on the actuator/channel briefly lights up green and then lights up green for a
further approx. 15 seconds.

The description of the connection test in the operating instructions for the sensors and actuators may differ from
this.
The HTFMA-180.161 actuator does not support the connection test.
14.6.7 Deleting room
You can use this function to remove the room from the list of rooms. This deletes all settings and trained sensors.
Actuators, which were not cancelled before the room was deleted, switch to emergency mode. More information
about emergency mode and cancelling can be found in the respective actuator operating instructions.
14.7 Automatic program
The switching times can be set in 15-minute intervals and setpoint temperatures programmed for this room. The switching
times can be transferred to other days of the week.
14.8 Central functions
These functions affect all rooms. Operating modes can thereby be quickly changed for the entire system, functions such as
party or holiday can be quickly activated or system settings quickly undertaken.
14.9 Setting up Internet access
In order to operate the b@home system outside your home network, you need to create a new user account or assign an
existing account to your b@home gate. To do this, open the configuration interface of the b@home gate (see Section
14.1.1).
Once a user account has been set up/assigned, the b@home system can be controlled and monitored from any location
using the b@home app or b@home portal by going to https://www.klimaregler.de.
When establishing the connection to the b@home portal, the system time set of the b@home gate is used to determine the
time zone for automatic time corrections. Ensure that the correct time has been set in the b@home gate (see Section 14.5)
before taking this step.
14.10 Factory settings
This function either partially or completely resets user settings. Follow the corresponding on-screen instructions.
14.11 Firmware update
Here you can view the installed firmware version of the b@home gate and look for updates. We always recommend
installing the most recent version. While an update is taking place, the two lamps on the b@home gate flash blue. If
necessary, once the update is complete, you can return to the previous firmware version.
While an update is taking place, do not disconnect the power supply or Internet connection to your b@home gate
because under certain circumstances, this may damage the system.

16. Basic information about wireless installations
The aim of the following information is to provide a basic overview of the technology and functions involved in wireless
transmission in the b@home system and to assist with planning the assembly of individual components.
16.1 Radio waves
Wireless signals are electromagnetic waves, which spread equally in all directions at the speed of light. Electromagnetic
waves include radio waves, microwaves, infrared radiation, visible light, UV radiation, X-ray radiation and gamma
radiation. The various types of waves differ in terms of their frequency and therefore their wavelength.
In contrast to light waves, radio waves can penetrate walls, ceilings and furniture.
The field strength of radio waves decreases quadratically as the distance between the transmitter and receiver increases,
i.e. if the distance between the transmitter and receiver doubles, the signal is just a quarter of its original strength.
16.2 Frequency band
Frequency ranges are assigned by the German Federal Network Agency. There are specified frequency ranges for every
application, e.g. for radio, TV, amateur radio, aircraft radio, taxi radio, police radio or mobile radio. There are specified
distances between these frequency ranges to prevent overlaps and resulting transmission issues.
Wireless components from alre transmit in what is known as the ISM range (Industrial, Scientific and Medical) with a
frequency of 868.3 MHz. This range has been allocated for high-frequency devices in industry, science and medicine but
also for domestic applications.
Using this range, b@home components operated in an open area can achieve ranges of at least 150 metres and in
buildings up to 30 metres.
The maximum permitted transmission power in this range within the milliwatt range is 10 mW. By way of comparison,
mobile phones work continuously with peak power outputs of up to 2000 mW.

Explanation
The Hertz unit:
•Named after the physicist Heinrich Hertz
•Number of recurring processes in one periodic signal per second.
•In antenna technology, this describes the number of recurring vibrations (positive and negative half-waves).
•Wireless or radio waves are stated using this unit as are sound waves in acoustics, for example

Hertz Hz 1 1 Hz
Kilohertz kHz 10³ 1000 Hz
Megahertz MHz 1061000 000 Hz
Gigahertz GHz 1091000 000 000 Hz
Terahertz THz 1012 1000 000 000 000 Hz
16.3 Signal strength / absorption
The signal strength is reduced by materials on the transmission path between the transmitter and receiver. This is known
as signal attenuation. The degree of attenuation is greatly dependent on the type, thickness and density of the material.
Material Penetration Example
Wood / wood with plasterboard Very good Internal partitions
Plastic Very good Plastic windows
Glass normal, metallised Good Window panes
Bricks Average External wall
Water Average People, aquariums
Concrete with steel reinforcements Poor Solid walls
Metal Very poor Fire doors
Additional attenuation from the following may also have to be taken into consideration:
•Installation of wireless components in a flush-mounted socket
•Metal coatings, e.g. on furniture and wall coverings
•Planted areas
•High air humidity

16.4 Shielding
Metallic building parts, furniture, wall coverings etc. shield electromagnetic waves. This produces what are known as radio
pockets where direct reception is not possible. Receivers can no longer receive the transmitter signals directly.
Radio pockets caused by a metal cabinet, for example
16.5 Reflexion / reflection
Furthermore, radio waves can be reflected by metal objects or surfaces. When this happens, they can either be allowed
to pass with great losses or reflected in full (and with a delay). In most cases, reflections are annoying and not desired.
They trigger polarisation and interference (see below).
However, the radio waves can still reach their destination by diverting to certain objects. Longer transmission paths in
particular can be bridged using reflexion.
Whether this works in your particular situation, depends greatly on the prevailing conditions and should be tested on a
case-by-case basis.
Examples of reflective media:
•Reinforced concrete walls
•Metal cabinets
•Mirrors with metallic surface
