Mounting

Please read this entire section before starting to mount the device

• The Homematic IP Radiator Thermostat is easy to install and can be done without draining heating water or intervening in the heating system. No special tools are required, nor does the heating have to be switched off.
• The metal nut (A) attached to the radiator thermostat can be used universally and without accessories for all valves with a throat size of M30 x 1.5 from the most popular manufacturers. You can find an overview and further information about compatible manufacturers and valve adapters at www.homematic-ip.com.
• Through the adapters in the delivery, the device can also be installed on radiator valves of type Danfoss RA, Danfoss RAV and Danfoss RAVL (see “5.2.4 Adapter for Danfoss” ).

Removing the thermostat
In case of visible damage to the existing radiator, valve or heating pipes, please consult a specialist.

Remove the old thermostat dial from your radiator valve

• Rotate the thermostat dial to the maximum value (1) anti-clockwise (see fig. 6). The thermostat dial then no longer presses against the valve spigot, making it easier to remove.

There are different ways of fixing the position of the thermostat dial

• Union nut: Unscrew the union nut in an anticlockwise direction (2). The thermostat head can then be removed (3).
• Snap-on fastenings: Thermostat heads that are fastened this way can be detached by turning the fastener/union nut a little bit counter-clockwise. The thermostat head can then be removed.
• Compression fitting: The thermostat dial is held in place by a mounting ring which is held together with a screw. Loosen this screw and remove the thermostat head from the valve.
• Threaded connection with set screw: Loosen the set screw and remove the thermostat head.

Mounting the radiator thermostat
After removing the old thermostat head, you can mount the new radiator thermostat on the heating valve:

• Place the radiator thermostat with the metal nut (A) on the heating valve (see fig. 7).
• Tighten the metal nut on the heating valve (see fig. 8).
• To make installation easier, you can remove the batteries from the battery compartment (C) and press the button in the battery compartment permanently while turning the metal nut onto the heating valve (see fig. 9). By pressing the button, the rotating mechanism of the radiator thermostat is blocked and the desired orientation of the display is easier to achieve.
• If required, you can use one of the supplied adapters for Danfoss valves (see “5.2.4 Adapter for Danfoss” on page 50) or the supplied support ring (see “5.2.1 Removing the thermostat”.

Support ring
The valves from different manufacturers may have tolerance fluctuations that make the radiator thermostat more loosely seated on the valve. In this case, the provided support ring should be placed into the flange before mounting the device (see fig. 10). You can then mount the radiator thermostat again as described above.

Adapter for Danfoss
One of the provided adapters is required to attach to Danfoss valves. The assignment of the suitable adapter to the relevant valve can be found in the following illustrations.

• Please ensure that you do not trap your fingers between the two halves of the adapter!
• The RA and RAV adapters have been manufactured with pre-tension to provide a better seat. Use a screwdriver during installation if necessary, and bend it open slightly in the vicinity of the screw (see following figures).

Danfoss RA
The Danfoss valve bodies have elongated notches around their circumference, which also ensure that the adapter is properly seated when it snaps on.

• During installation, please ensure that the pins inside the adapter are lined up with the notches on the valve.
• Snap the adapter completely onto the valve.
• Attach the adapter using the provided screw and nut.

Danfoss RAV

• The Danfoss valve bodies have elongated notches around their circumference, which also ensure that the adapter is properly seated when it snaps on.
• During installation, please ensure that the pins inside the adapter are lined up with the notches on the valve.
• Snap the adapter completely onto the valve.
• Attach the adapter using the provided screw and nut.
• Place the spigot extension on the valve pin.

Danfoss RAVL

• The Danfoss valve bodies have elongated notches around their circumference, which also ensure that the adapter is properly seated when it snaps on.
• During installation, please ensure that the pins inside the adapter are lined up with the notches on the valve.
• Snap the adapter completely onto the valve.
• Place the spigot extension on the valve pin.
• The RAVL adapter does not need to be screwed on.

Adaption run

• Once the batteries have been inserted, the motor reserves. Meanwhile, “  and the activity symbol ( ) is displayed.
• If the adapter run has been initiated before mounting or if an error message (F1, F2, F3) is displayed, press the system button (D) the motor reverses to the “  position. The adaptation run can then be restarted.
• After the radiator thermostat has been mounted successfully, an adaption run ( ) has to be performed to adapt the device to the valve. To do this, proceed as follows:
• As soon as “  is displayed, press the system button (D) to start the adaption run.
• If the display backlight is off, you must press but- ton (D) a second time to start the adaption run.
• Now, the radiator thermostat performs the adapting run. “ and the activity symbol ( ) is displayed. During this time, no other operation is possible. After the adapt- ing run has been successful, the display returns back to normal. You can now start operating the radiator ther- mostat.

Operation

After adding and mounting have been performed, simple operations are available directly on the device. Further information on operation via the Homematic IP app can be found in the Homematic IP user guide at www.homematic- ip.com.

• If the radiator thermostat is in stand-by mode, press the system button (D) once to activate the display before using the device.

• Temperature: Turn the temperature control dial (E) slightly to the right or to the left to change the temperature of the radiator. In automatic mode, the manually set temperature will remain the same until the next point at which the profile changes. Afterwards, the defined heating profile will be activated again via the app. During manual operation, the temperature remains activated until the next manual change.

• Boost function: Press the system button (D) briefly to activate the boost function for heating up the radiator quickly and briefly by opening the valve. There will be a pleasant room temperature right away because of the radiated heat.

• Adjusting the display direction: Press the system button (D) and at the same time turn the temperature control dial (E) in the direction you want the display to turn (see fig. 11). The display will rotate by 180°.

• The operating lock of the radiator thermostat can be activated and deactivated via the Homematic IP app. Tap on the menu symbol in the top left of the screen of your app and select the menu item “Device overview”. Select your radiator thermostat to switch the operating lock “ON” or “OFF”.

Replacing batteries

If the symbol for empty batteries ( ) appears in the dis- play or in the app, please replace the used batteries by two new LR6/mignon/AA batteries. You must observe the correct battery polarity.

• Remove the empty batteries.
• Insert two new 1.5 V LR6/mignon/AA batteries into the battery compartment, making sure that you insert them the right way round (see fig. 12).
• Slide the battery compartment cover (C) back on from the bottom upwards (see fig. 5).
• Once the batteries have been inserted, the radia- tor thermostat will perform a self-test (approx. 2 seconds). This is followed by the initialisation ( ) and a test display (orange and green light).
• Start the adaption run ( ) again by pressing the system button (D).

Used batteries should not be disposed of with regular domestic waste! Instead, take them to your local battery disposal point.

Caution! There is a risk of explosion if the battery is not replaced correctly. Replace only with the same or equivalent type. Never recharge non- rechargeable batteries. Do not throw the batteries into a fire. Do not expose batteries to excessive heat. Do not short-circuit batteries. Doing so will present a risk of explosion.
Caution! Avoid skin and eye contact with leaking batteries! Wear suitable protective gloves when removing leaking batteries and residues from a device! In case of skin contact flush with plenty of water!

Troubleshooting

• Provided that the voltage value permits it, the radiator thermostat will remain ready for operation also if the bat- tery voltage is low. Depending on the particular load, it may be possible to send transmissions again repeatedly, once the batteries have been allowed a brief recovery period.
• If the voltage drops too far during transmission, the emp- ty battery symbol ( ) and the corresponding error code will be displaved on the device (see “8.4 Error codes and flashing sequences” ). In this case, replace the empty batteries by two new batteries (see “7 Replac- ing batteries”).

Command not confirmed
If at least one receiver does not confirm a command, the device LED (D) lights up red at the end of the failed transmission process. The failed transmission may be caused by radio interference (see “11 General information about radio operation” on page 64). The failed transmission may also be caused by the following:

• Receiver cannot be reached.
• Receiver is unable to execute the command (load failure, mechanical blockade, etc.).
• Receiver is defective.

Duty cycle
The duty cycle is a legally regulated limit of the transmission time of devices in the 868 MHz range. The aim of this regulation is to safeguard the operation of all devices working in the 868 MHz range. In the 868 MHz frequency range we use, the maximum transmission time of any device is 1% of an hour (i.e. 36 seconds in an hour). Devices must cease transmission when they reach the 1% limit until this time restriction comes to an end. Homematic IP devices are designed and produced with 100% conformity to this regulation. During normal operation, the duty cycle is not usually reached. However, repeated and radio-intensive adding processes mean that it may be reached in isolated instances during start-up or initial installation of a system. If the duty cycle is exceeded, this is indicated by one long red lighting of the device LED (D), and may manifest itself in the device temporarily working incorrectly. The device starts working correctly again after a short period (max. 1 hour).

General information about radio operation

• Radio transmission is performed on a non-exclusive transmission path, which means that there is a possibility of interference occurring.
• Interference can also be caused by switching operations, electrical motors or defective electrical devices.
• The range of transmission within buildings can differ greatly from that available in the open air.
• Besides the transmitting power and the reception characteristics of the receiver, environmental factors such as humidity in the vicinity have an important role to play, as do on-site structural/ screening conditions.
