INTENDED USE
Using the radio radiator thermostat, you can regulate the room temperature in a time- controlled manner and define heating phases according to your individual requirements, The room temperature is controlled by the radiator valve via the brennenstuhi*Connect fadiator thermostat.

INSTALLATION INFORMATION / DISTANCE TO SOURCES OF INTERFERENCE

This device works with the 2.4 GHz Zigbee protocol. The reach within buildings may strongly differ from the one in open areas.
Apart from the transmission power and the reception properties of the receivers, environmental influences such as air humidity and the structural situation on site play an important role.
The reach may be considerably reduced by:

• Walls made of wood, plasterboard, concrete, reinforced concrete
• Proximity to metal and conductive objects
• Broadband interference, e.g. in residential areas (DECT phones, mobile phones, radio headphones, radio speakers, radio weather stations, baby monitoring systems)
• Proximity to electric motors, transformers, power supply units, computers

ASSEMBLY AT THE RADIATOR

The radiator thermostat can be assembled without draining heating water as it is not necessary to make any changes in the heating system itself. For the assembly, you only need a slotted or Philips screwdriver.
The radiator thermostat is equipped with a universal union nut (4) (M30x1.5 mm) and is thus suitable for the following valves without adapter:

• Heimeier
• MNG
• Junkers
• Honywell-Braukmann
• Landis/&Gyr (Duodyr)| • Oventrop
• Schlösser
• Comap
• Valf Sanayii| • Mertik Maxitrol
• Watts
• Wingenroth (Wiroex)
• R.B.M| • Tiemme
• Jaga
• Siemens
• Idmar
---|---|---|---

For Danfoss valves, you need the following adapter

Heimeier, Junkers, MNG, Honywell-
Braukmann, … etc. (see complete list
under “Assembly at the radiator“)| | Not required
Danfoss RA| | See enclosed adapters
Danfoss RAV| | See enclosed adapters
Danfoss RAVL| |

DISASSEMBLY OF THE ORIGINAL HEATING CONTROLLER

There are many different types of heating valves and thus also many different fastening systems. If possible, use the original instructions of the radiator thermostat for disassembly. First of all, set the original heating controller to the maximum value (A) by rotating it counterclockwise.
The valve is completely opened and the controller no longer pushes on the valve pin. Different disassembly options:
Union nut
Screw off the union nut by rotating it counterclockwise (B). Afterwards, you can remove the thermostat head.
Snap fastening
You can easily loosen thermostat heads fastened in this way be rotating the lock/union nut a little bit counterclockwise (C).
Afterwards, you can remove the thermostat head The system is only suitable for controlling radiators. Any other use e.g. at cooling systems or underfloor heatings etc. is not admissible.
INFORMATION ON THE USE OF THE RADIATOR THERMOSTAT WITH THE BRENNENSTUHL°CONNECT APP
To be able to enjoy the full functionality of the radiator thermostat, you need the brennenstuhl® Zigbee gateway GWY CZ 01 art. no. 1294060 to use the brennenstuhlConnect app and for connection into the network.
The gateway is the connection between the WiFi network and the brennenstuhlConnect Zigbee radio products. To be able to use battery-operated products for a longer period of time, it is necessary to use the Zigbee radio technology.

INSTALLATION

1. Keep the setting wheel pressed for 3 seconds before mounting the radiator thermostat on the heating valve.

2. Shortly before F1 and the installation symbol flash, the radiator thermostat vibrates gently.
   Please turn to continue reading →

3. Now screw the radiator thermostat on the valve by means of the union nut (for Danfoss valves, use the enclosed adapter). Slightly push the union nut forwards and rotate it clockwise onto the valve thread. The maximum torque of 5 Nm must not be exceeded.

4. Keep the setting wheel pressed again until F12 appears.

5. After ca. 10 seconds, the installation symbol goes out and the current temperature is displayed. The installation is completed.

INSTALLATION / ADJUSTMENT DRIVE

1. After the installation, the radiator thermostat is automatically adjusted to the radiator valve. For this purpose, the radiator thermostat opens and closes the valve to determine the opened position and the closed position of the heating valve.
2. If the process ends with an error, check whether the union nut is still screwed tight or whether the adapter has loosened. Afterwards, remove the batteries for 10 seconds.
   Then, re-insert the batteries into the radiator thermostat and activate the installation mode to start the automatic adjustment.
   To ensure proper functioning of the radiator thermostat, the influence of the thermal radiation of the radiator should be kept to a minimum. Please install the radiator thermostat as shown in the figure below.

OPERATION

1. Mode: Automatic The radiator thermostat automatically sets the desired temperature which has been defined in the brennenstuhl® Connect app before. For automatic mode, the radiator thermostahas to be connected to the brennenstuhl® Zigbee gateway art. no. 1294060 and the radio network must be active.
2. Mode: Manual In the manual mode, the temperature can be fixedly set manually using the setting wheel. The temperature can be set between 5 and 30 °C.
3. Mode: Frost protection The frost protection mode is intended for keeping rooms free from frost so that, for example, water lines cannot freeze in at low temperatures. In frost protection mode, the temperature can be set between 5 and 15 °C.

ACTIVATING THE CHILD PROTECTION DIRECTLY AT THE RADIATORTHERMOSTAT

To activate/deactivate the child protection, you keep the setting wheel pressed for 3 seconds. If the child protection is active, no operation is possible any more at the radiator thermostat. The child protection is intended to prevent children from changing the radiator thermostat setting or other kinds of accidental tampering with the radiator thermostat.
If the child protection is active, a padlock symbol is shown in the display. OPEN WINDOW DETECTION (can only be set in the brennenstuhl®Connect app)
The Open window function can be activated or deactivated in the brennenstuhl®Connect app. If the function is activated, the radiator thermostat detects an open window and closes the valve for 30 min. In this way, the heat loss can be reduced. The Open window function is activated by default. To deactivate/activate the Open window function, open the brennenstuhl®Connect app and select the window symbol for activation or deactivation. VALVE ADJUSTMENT (can only be set in the brennenstuhl®Connect app) If the valve adjustment has been activated in the app, an automatic valve adjustment will be carried out if necessary.
