According to your personal needs, you can create three dierent heating schedules with up to 6 heating phases per day. In the climate control solution, the ra- diator thermostat can simply be paired with the HomematicIP Access Point. In combination with the HomematicIP Window / Door Contact, for example, the temperature is automatically re- duced during ventilation. For precise regulation of the room temperature, the HomematicIP Wall Thermostat with humidity sensor can measure the actual temperature of a room and transmit the data to the radiator ther- mostat. This ensures that the temper- ature is measured at the right place in the room. The radiator thermostat fits all com- mon radiator valves and is easy to in- stall - without having to drain any wa- ter or intervene in the heating system. With the additional boost function, the radiator can be quickly heated by opening the valve.

Please read this section complete- ly before starting the installation process. The HomematicIP Radiator Thermo- stat is easy to install, and requires no draining of heating water or interven- tion in the heating system. No special tools are required, nor does the heat- ing have to be switched o. The metal nut attached to the radiator thermostat can be used universally and without accessories for all valves with a thread size of M30 x 1.5 mm from lead- ing manufacturers such as

• Idmar Using the adapters supplied, the device can also be installed on Danfoss RA, Danfoss RAV and Danfoss RAVL radia- tor valves(see „6.2.2 Adapter for Dan- foss“ on page 22).

6.2.1 Fitting the radiator thermostat

In case of visible damage to the existing thermostat, valve or heat- ing pipes, please consult a spe- cialist. Remove the old thermostatic head from your radiator valve.

• Rotate the thermostatic head to the maximum value (N) (anticlock- wise). The thermostatic head then no longer presses against the valve spindle, making it easier to remove. Figure 4

The thermostatic head may be held in place in various ways:

• Union nut: Unscrew the union nut in an anticlockwise direction (O). The thermostatic head can then be removed (P).

• Snap-on fastenings: Thermostat- ic heads that are fastened in this way can be detached by turning the fastener/union nut slightly in anticlockwise direction (O). The thermostatic head can then be re- moved (P).

• Clamp fittings: The thermostatic head is held in place by a mounting22 Start-up ring, which is held together with a screw. Loosen this screw and re- move the thermostatic head from the valve (P).

• Threaded connection with set screw: Loosen the set screw and remove the thermostatic head (P)

After removing the old thermostatic head you can install the HomematicIP Radiator Thermostat with the metal nut (A) on the radiator valve. Figure 5 If required, you can use one of the adapters for Danfoss valves (see „6.2.2 Adapter for Danfoss“ on page 22) or the support ring supplied (see „6.2.3 Support ring“ on page 24).

6.2.2 Adapter for Danfoss

One of the adapters supplied is re- quired to attach to Danfoss valves. The assignment of the suitable adapter to the relevant valve is shown in the fol- lowing illustrations. Please be careful not to trap your fingers between the two halves of the adapter! The RA and RAV adapters have been manufactured with pre-tension for a better fit. Use a screwdriver during in- stallation if necessary, and bend it open slightly in the vicinity of the screw. Danfoss RA The Danfoss valve bodies have elon- gated notches (1) around their cir- cumference, which also ensure that the adapter is properly seated when it snaps on. During installation, please ensure that the pins inside the adapter (2) are lined up with the notches (1) on the valve. Ensure that a suita- ble adapter for the valve is prop- erly clipped on. After clipping onto the valve body, please attach the adapter using the provided screw and nut. Figure 6

During installation, please ensure that the pins inside the adapter (2) are lined up with the notches (1) on the valve. Ensure that a suita- ble adapter for the valve is prop- erly clipped on. The lifter extension (3) must be fitted to the valve pin of RAV valves prior to installation. Figure 7

RAV Danfoss RAVL The Danfoss valve bodies have elon- gated notches (1) around their cir- cumference, which also ensure that the adapter is properly seated when it snaps on. During installation, please ensure that the pins inside the adapter (2) are lined up with the notches (1) on the valve. Ensure that a suita- ble adapter for the valve is prop- erly clipped on. The adapter RAVL does not have to be screwed. Figure 8

The valves from dierent manufactur- ers may have tolerance fluctuations that make the radiator thermostat more loosely seated on the valve. In this case, the support ring provided (R) should be inserted into the flange be- fore fitting the radiator thermostat. Figure 9

When the batteries are inserted, the motor retracts to simplify installation. Meanwhile, “

and the activity symbol ( ) are displayed. After the radiator thermostat has been fitted successfully, an adjustment run ( ) must be performed to adapt the device to the valve. To do this, proceed as follows:

• As soon as “ ” is displayed, press the control wheel/boost but- ton (E) to start the adjustment run. If the display backlight is o, you must press button (E) a second time to start the adjustment run. The actuator now performs an adjust- ment run. “ ” and the activity sym- bol ( ) are displayed. During this time, no other operation is possible. After the adjustment run has been success- ful, the display returns to normal. If the adjustment run has been initiated prior to fitting or if an error message (F1, F2, F3) is dis- played, press the control wheel/ boost button (E) and the motor reverses to the “ ” position. 7 Operation After pairing and mounting have been performed, simple operations are avail- able directly on the device. If the radiator thermostat is in standby mode, please press the control wheel (E) once before operation to activate the device.

• Temperature: Turn the control wheel (E) to the right or to the left to manually change the tempera- ture of the radiator. In automatic mode, the manually set tempera- ture will remain the same until the next point at which the schedule changes. Afterwards, the defined heating schedule will be enabled again. During manual mode, the temperature remains activated un- til the next manual change.

• Manual and automatic mode: Press and hold down the control wheel (E) to switch between manual and automatic mode. In automatic mode, the defined heating sched- ule of the HomematicIP App is25 Changing the batteries active. In manual operation, the temperature can be set directly on the device or via the app and will remain active until the next manual change.

• Boost function: Press the con- trol wheel (E) shortly 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. The operating lock of the radiator thermostat can be activated and deactivated via the HomematicIP 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”. 8 Changing the batteries If the symbol for empty batteries ( ) appears in the display or in the app, please replace the used batteries by two new LR6/mignon/AA batteries. You must observe the correct battery polarity. To insert the batteries into the radiator thermostat, please proceed as follows:

• Push the battery compartment cover (D) backwards and then downwards to remove it from the device. Figure 10

• Remove the batteries.26 Troubleshooting

• Insert two new 1.5 V LR6/Mignon/ AA batteries into the battery com- partment, making sure that you insert them the right way round as shown. Figure 11

• Close the battery compartment (D).

• After inserting the batteries, pay attention to the flashing sequences of the LED (see „9.4 Error codes and flashing sequences“ on page 28). Once the batteries have been inserted, the radiator thermostat will perform a self-test (approx. 2 seconds). After- wards, initialisation is carried out. The LED test display will indicate that in- itialisation is complete by lighting up orange and green. Caution! There is a risk of explo- sion if the batteries are not re- placed correctly. Replace only with the same or equivalent type. Never recharge non-rechargeable batteries. Do not throw the bat- teries 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 contact with the skin and eyes when handling leak- ing batteries. Wear suitable pro- tective gloves when removing leaking batteries and residues from a device. Rinse with plenty of water in case of contact with the skin. 9 Troubleshooting

Provided that the voltage value permits it, the radiator thermostat will remain ready for operation even if the battery voltage is low. Depending on the par- ticular 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 empty battery symbol

) and the corresponding error code will be displayed on the device, (see „9.4 Error codes and flashing sequenc- es“ on page 28). In this case, replace the empty batteries with two new ones (see „8 Changing the batteries“ on page 25). If an empty battery has not been rec- ognized, the radiator thermostat moves back into a “valve error posi- tion”. This avoids, that the set tem- perature in the room increases due to a low battery. A valve error position of 15% is set in the factory settings.27 Troubleshooting

9.2 Command not confirmed

If at least one receiver does not con- firm a command, the device LED lights up red at the end of the failed trans- mission process. The reason for the failed transmission may be radio inter- ference (see „12 General information about radio operation“ on page 30). This may be caused by the following:

• Receiver cannot be reached.

• Receiver is unable to execute the command (load failure, mechanical blockage, etc.).

The duty cycle is a legally regulated limit of the transmission time of de- vices 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 sec- onds in an hour). Devices must cease transmission when they reach the 1% limit until this time restriction ends. HomematicIP 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 pairing processes mean that it may be reached in isolated instances during start-up or initial installation of a system. If the duty cycle limit is exceeded, the device may stop working for a brief period. The device starts working correctly again after a short period (max. 1 hour).28 Troubleshooting
