Displays the HT2 network state. Segment visible: rf-link
established / Segment turned off: rf-link lost
ID: Lights up if the display shows the Z-Wave NodeID
Battery: Lights up if less than 15% battery is remaining
Lock: Lights up if child protection is set

Inserting batteries
Remove the battery cover by simply pulling it off. Now insert the batteries. Pay attention to the
correct polarity! At a later battery change, the configuration of your HT2 is maintained.
4.4 Inclusion
Start inclusion mode of your primary Z-Wave controller.
Press the Boost-Button.
The heating thermostat HT2 will show the assigned NodeID

4.5 Mounting the heating thermostat HT2
After adding the HT2 to a network it is ready to be installed on the radiator. The LCD shows INS. Do
not press the boost button yet. If successfully installed to the radiator proceed with 4.6.

4.6 Mechanical installation
Press the boost button to start the mechanical installation.

4.7 Exclusion
Start Exclusion mode of your primary Z-Wave controller. Now press and hold the boost button of
the HT2 for at least 5 seconds.
4.8 Unmounting the heating thermostat HT2
Remove the HT2 from the Z-Wave network before unmounting it. Follow the process described in
Exclusion and wait until the LCD shows INC. You can now uninstall the HT 2 from the radiator.

4.9 Factory reset
Remove batteries. Press and hold boost button. While still holding boost button insert batteries.
The LCD shows RES. Release boost button. To perform the factory reset press boost button.
5.0 OPERATING DEVICE
The LCD shows the configured set point or the valve opening percentage if the device is in
manufacturer specific mode.
5.1 Set point adjustment
The set point is adjusted via plus and minus button. Altering the set point locally will set the HT 2 in
heating mode. The energy saving set point can only be adjusted via Z-Wave. The configurable set
point is 8 C to 28 C.
If the set point is increased /decreased above/below the set point limits the HT2 will change into
boost/off –mode.
5.2 Child protection
Press and hold plus and minus button simultaneously for 3 seconds to enable/disable the child
protection. If the HT2 is set into the highest protection level it is no longer possible to operate the
device locally.
5.3 Altering the operating states
Off-Mode
Press minus button until OFF is displayed.
Boost-Mode
Press the boost button. Alternatively press the plus button until ON is displayed.
Heating-Mode
If the operating state is not heating mode, pressing the plus or minus button will bring the device in
heating mode.

5.4 Window open detection
If the roomtemperature drops the window open detection will trigger. Heating thermosat HT 2 will
change temporarily in off mode for 15 minutes. Window open detection will end automatically after
15 minutes and the previously active operating mode will be restored. Window open detection can
also be canceled by a button press. The window open detection is disabled during manufacturer
specific mode. The sensitivity of the window open detection can be configured.
5.5 Display NodeID
Press and hold the boost button for 3 seconds to display the NodeID.

6.1 Association
Heating thermostat HT2 can only be associated with the Z-Wave controller
6.2 Basic
Control basic functions of the heating thermostat HT2 via basic command class.

6.3 Configuration
Heating thermostat HT2 can be configured during runtime.
6.4 Multilevel sensor
Heating thermostat measured the room temperature and automatically reports sensor readings to
associated devices. Per default the reporting threshold is +/-0.5 C. This parameter can be altered via
configuration command class.
The measured room temperature can be adjusted with an offset. The heating thermostat HT2 can
receive temperature readings from other Z-Wave devices (wall thermostat for example). The
external temperature can be used for temperature regulation. This feature has to be anabled via
configuration parameter. The HT2 can handle multilevel sensor reports in the following format:

6.5 Multilevel Switch
Allows to request the valve opening in percent. 0% represents a fully shut valve. 100% a fully open
valve. The valve opening can be reported on change. If the configuration parameter is set.
Controlling the valve directly via multilevel switch command class is only possible if the heating
thermostat HT2 is in manufacturer specific mode
6.6 Notification
Heating thermostat HT2 will send notifications on certain events.
6.7 Protection
Heating thermostat HT2 can be locked remotely.
6.8 Thermostat Mode
Heating thermostat HT2 offers following modes.

6.9 Thermostat set point
The following set points of the heating thermostat HT2 can be altered.
7.0 Troubleshooting
Replace batteries
Adjust temperature of the boiler water. Remove the HT2,
move the valve back and forth per hand or with a tool
Unmount HT2. Move the valve stem several times by hand,
it may be that adaption is impossible because your valve is
calcified or the seat no longer performs it function.
Remove batteries. Out in the pressure piece. Insert the
batteries. The endless thread is rotating now and fixes the
pressure piece again.
Z-wave controller out of range
Check if the valve is jammed
Check if the HT2 is correctly mounted
Check if the HT2 is correctly mounted
