The Comet Zigbee does not belong to any Zigbee network ex works. The Comet Zigbee must be added to an existing
network in order to communicate with other Zigbee devices. This process is called inclusion. The Comet Zigbee can also
leave a network. This operation is called removal (exclusion). Both operations must be initiated by a primary Zigbee con-
troller. To do this, the controller must be put into Add or Remove mode. Please refer to the user manual of your Zigbee
controller how to start the modes. Only when the primary controller is in add/remove mode, Zigbee devices can join
or leave the network. If the device already belongs to a network, the device must first be removed from the network.
Otherwise, the join attempt will fail.
Behavior in the Zigbee network
The Comet Zigbee can be added to any Zigbee network and operate with other Zigbee certified devices and/or applica-
tions from other manufacturers. All non-battery powered network nodes (nodes), regardless of manufacturer, act as
repeaters within the network and improve the reliability of the wireless network.
Network security
Comet Zigbee can communicate encrypted with other Zigbee devices, if they also support encrypted communication. If
this is not the case, Comet Zigbee communicates unencrypted.
NOTE: To use the full functionality of the Comet Zigbee, a security enabled Zigbee controller is required.
5. INSTALLATION
Remove the battery cover by pulling it upwards by the notch (Fig.1).
Now insert the batteries. Pay attention to the correct polarity! Do not use rechargeable batteries!
Reattach the battery cover to the Comet Zigbee (Fig.2) by pressing it on until it clicks.
In case of a later battery change, the configuration of your Comet Zigbee will be preserved.

5.3 MOUNTING AT A RADIATOR
After adding (inclusion), the LED display shows an animation and the thermostat moves to the mounting position. Sub-
sequently, the LED display shows “Ad”.
Follow the mounting steps below:
1. Unscrew old thermostatic head completely, loosen fastening and pull it off the valve (fig.3).
2. If necessary, select a suitable adapter and mount it on the valve (Fig.4).
3. Screw the thermostat onto the valve or adapter by turning the union nut clockwise (Fig.5).
When you have mounted the Comet Zigbee on the valve, continue with 5.4 Adaptation.

5.4. ADAPTERS
NOTE:
Remove the connecting pieces of the plastic adapters completely (Fig.6) before using one of the enclosed adapters! For
Danfoss RA/RAV use the enclosed screw and nut.
No adapter is required for the following valves:
Heimeier; Junkers Landys+Gyr; MNG; Honeywell; Braukmann, as these have a thread dimension of M30 x 1.5 mm.
The adapters for Danfoss RAV (pin must be plugged on valve tappet), Danfoss RA and Danfoss RAVL are enclosed.
You will need an adapter for the following valves:
Herz M28 x 1,5 mm; Comap M28 x 1,5 mm; Vaillant 30,5 mm; Oventrop M30 x 1,0 mm; Meges M38 x 1,5 mm; Ondal
M38 x 1,5 mm; Giacomini 22,6 mm; Rossweiner M33 x 2,0 mm; Markaryd M28 x 1,0 mm; Ista M32 x 1,0 mm; Vama

Remove the Comet Zigbee from the network before disassembling the device. To do this, please put your Zigbee
controller in the removal mode (Exclusion). Then press and hold the button in the battery compartment for 5 seconds
(Fig.7). The LED display shows Node ID 0 if the removal was successful and the valve tappet moves into mounting po-
sition. Wait until the display shows “PA”. Now unscrew the union nut counterclockwise and remove it from the Comet
Zigbee valve (Fig.8).
Press and hold the button in the battery compartment of your Comet Zigbee for at least 10 seconds. From the 5th
second on, a counter will run on the thermostat’s display. Keep the button pressed until the 10 appears on your Comet
Zigbee. Then “Ad” will be shown again on the display and the controller will be in pairing mode.
NOTE: Use the factory reset only if your primary Zigbee controller is no longer available or is inoperable for other rea-
sons.

6 OPERATING THE DEVICE
The LED display shows the set setpoint temperature or the set valve opening degree when the Comet Zigbee is operat-
ed in the actuator mode.
6.1 SETTING THE TARGET TEMPERATURE
The set temperature is changed via the and button.
The local change of the setpoint temperature puts the Comet Zigbee in heating mode.
The setpoint temperature of the setback mode can only be adjusted by radio.
The input range of the set temperature is 8°- 28°C.
If the temperature is increased or decreased beyond this, the Comet Zigbee will switch to boost or off mode.
6.2 CHILD PROTECTION / KEY LOCK
The child protection/key lock can be switched on and also switched off again by simultaneously holding down the
and button for 3 seconds, when the display is off.
If the Comet Zigbee is set to the highest protection level by radio, local operation is no longer possible. The child safety
lock can then also no longer be removed locally.
6.3 CHANGING THE OPTERATING MODE
OFF-Mode
Press the key as long as “--” is displayed on your thermostat.
Heating-Mode
If the device is not in the heating-mode, change the temperature by using keys, between 8 to 28 degrees.
Boost-Mode
If your device is not in the Boost-mode, keep the key pressed, until the device displays “ON”
6.4 WINDOW OPEN DETECTION
If the temperature drops abruptly, the window open mode is activated. The Comet Zigbee will switch to off mode for 10
minutes. The window-open mode is automatically exited after 10 minutes and the previously active mode is restored.
In Manufacturer Specific Mode, the window-open detection is not executed.
The sensitivity of the window open detection can be configured.

The warranty period is 24 months and starts on the day of purchase. Please keep the receipt as proof of purchase.
During the warranty period, defective energy-saving controllers can be sent to the service address below with sufficient
postage. You will then receive a new or repaired device back free of charge. Repair or replacement of the device does
not start a new warranty period. Please note that we only guarantee the functions of the device, not the functionality
between the interaction of the thermostat and the valve base.
The application-related technical data are guaranteed only together with the valves Heimeier, Junkers Landys+Gyr,
MNG, Honeywell Braukmann thread dimension (M30x1,5), Oventrop (M30x1,5) Danfoss RA, RAV and RAVL. The device
combinations can be taken from our website (https://eurotronic.org/service/faq). When operating the thermostat with
third-party valves/adapters that are not listed, the functionality must be ensured by the user. Eurotronic does not pro-
vide any warranty service in these cases. After the warranty period has expired, you also have the option of sending the

13. LEGAL INFORMATION
Dispose of thermostat:
(Applicable in the European Union and other European countries with systems for separate collection of recy-
clable materials). Old devices must not be disposed of with household waste! If the thermostat can no longer
be used, every consumer is required by law to dispose of old devices separately from household waste, e.g. at a
collection point in his community/borough. This ensures that old appliances are recycled properly and that neg-
ative effects on the environment are avoided. This is why electrical appliances are marked with the symbol shown here.
Batteries and rechargeable batteries must not be disposed of with household waste!
As a consumer, you are required by law to take all batteries and rechargeable batteries, whether they contain
harmful substances* or not, to a collection point in your municipality/borough or to a retailer so that they can be
disposed of in an environmentally friendly manner.
Dispose of packaging:
Dispose of the packaging according to type. Put cardboard and carton in the waste paper collection, foils in the
recyclables collection.
Konformitätserklärung:
