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.

This manual provides information about the following:
1. Assembling and connecting the b@home gate
2. Setting up b@home system
3. Basic information about wireless installations and optimum placing of the b@home components
Information about assembly and connecting the sensors and actuators to the power supply can be found in the relevant
operating instructions.
Further information can be accessed from the following locations:
3. Safety information
The applicable safety regulations should be observed. After installation, the installation company should instruct the
operator in how the control system works and how to operate it. The operating instructions must be stored somewhere
freely accessible to operating and maintenance staff.
Operating the system in the vicinity of devices, which do not comply with the EMC regulations, may affect the device
functions.
Do not open the b@home gate or wall power supply under any circumstances.
The b@home gate, FTRFB-280.1xx sensors and HTFMA-180.161 and HTFRA-010.101 actuators must not be
disposed of in general household waste.
4. Quick start instructions
1.) Fit b@home gate (see Section 12.).
2.) Use Ethernet cable to connect b@home gate to a free LAN port on the router (see Section 13.).
3.) Use wall power supply to connect b@home gate’s power supply (see Section 13.).
4.) Open b@home-app on an end device logged onto the home network (see Section 14.1.2).
5.) Define system function (see Section 14.3).
6.) Set up rooms (see Section 14.6.).
7.) Enter switching times and temperatures of automatic programs (see Section 14.7).
8.) Set up Internet access (see Section 14.9.).

6. System requirements
•Router with free Ethernet port (LAN), automatic IP address allocation must be activated (DHCP)
•IPv4
•Freely accessible power socket (230 V/50 Hz)
•Internet access for accessing from outside the home network
•Mobile end device (iOS 7.0 or Android 2.2 or higher) or computer with browser (Internet Explorer Version 10 or higher,
Firefox Version 23 or higher, Chrome Version 29 or higher, Opera Version 20 or higher, Safari Version 5.1.7 or higher)
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.
1. 2. 3. 4.
1. Use drill template provided to drill the holes
2. Insert dowels
3. Screw in screws approx. 3 mm
4. Insert b@home gate at an angle and turn into final position
ALRE-IT Regeltechnik GmbH hereby declares that the MGCBB-064.360 wireless system corresponds to the
2014/53/EU Directive. The complete text of the EU declaration of conformity is available at:

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
