• If pairing was successful, the LED lights up green. The device is now ready for use.

• If the LED lights up red, please try again.

• Select the desired solution for your device.

• Allocate the device to a room and give the device a name.

• The configuration is then carried out in the HomematicIP app.

Please read this entire section before starting the installation. You can use the supplied clip-on frame (A) to mount the wall thermostat or ea- sily integrate it into an existing switch (see „6.2.4 Installation in multiple combi- nations“ on page 23). If you want to mount the wall thermo- stat with the supplied clip-on frame, you can use

• the supplied double-sided adhesive strips or

• the supplied screws to fix it to a wall. You can also mount the wall thermos- tat on a flush-mounting box.

6.2.1 Adhesive strip mounting

For mounting the assembled wall ther- mostat with the adhesive strips, please proceed as follows:

• Choose a site for installation. Make sure that the mounting sur- face is smooth, solid, non-distur- bed, free of dust, grease and sol- vents and not too cold to ensure long-time adherence.

• Fix the adhesive strips (G) on the back side of the mounting plate (F) in the provided area. Make sure that you can read the letters on the back side (H) and that the clips on the mounting plate latch into the openings on the wall thermostat.21 Start-up

Remove the protective film from the adhesive strips.

• Press the assembled wall thermos- tat with the back side to the wall in the position where it should subse- quently be attached.

6.2.2 Screw mounting

For mounting the wall thermostat by screws, please proceed as follows:

• Choose a site for installation. Make sure that no electricity or similar lines run in the wall at this location!

• Position the mounting plate (F) on the desired site on the wall. Make sure that the arrow on the moun

ting plate is pointing upwards.

Use a pen to mark the positions of bore holes (J) (diagonally opposite) in the mounting plate on the wall.

Now drill the bore holes. If you are working with a stone wall, use a 5 mm drill bit for the wall plugs supplied. If you are working with wooden walls, you can use a 1.5 mm drill bit to make it easier to screw in the screws.

• Use the supplied screws and plugs (K) to fasten the mounting plate to the wall.

Attach the clip-on frame (A) to the mounting plate.22 Start-up

• Place the electronic unit (B) back into the frame. Make sure that “TOP” and the arrows on the back side point upwards and that the clips on the mounting plate latch into the openings on the electronic unit.

6.2.3 Mounting on flush-mounted

boxes You can mount the wall thermostat on flush-mounting/installation boxes using the holes (I) (see figure). If the device is mounted to a flush-mounting box, there may be no open conductor ends. If changes or works have to be made on the house installation (e.g. extension, bypass of switch- or socket inserts) or the low-vol- tage distribution for mounting or installing the device, the following safety instruction must be consi- dered: Please note! Only to be installed by persons with the relevant elec- tro-technical knowledge and experience!* Incorrect installation can endanger

• and the lives of other users of the electrical system. Incorrect installation also means that you are running the risk of serious damage to property, e.g. from fire. You risk personal liability for personal injury and property damage. Consult an electrician! *Specialist knowledge required for ins- tallation: The following specialist knowledge is particularly important during installati- on:

• The “5 safety rules” to be used:disconnect from mains; sa- feguard from switching on again; check that no voltage is present in system; earth and short circuit; cover or cordon o neighbouring live parts;

• Select suitable tool, measuring equipment and, if necessary, per- sonal safety equipment;

• Evaluation of measuring results;

• Selection of electrical installation material for safeguarding shut-o conditions;

• IP protection types;

• Installation of electrical installation material;

• Type of supply network (TN sys- tem, IT system, TT system) and the resulting connecting conditions (classical zero balancing, protective earthing, required additional mea- sures etc.).23 Operation

6.2.4 Installation in multiple

combinations You can mount the wall thermostat with the attachment frame (A) provided or use it with frames of other manu- facturers as well as integrate the elec- tronic unit (B) into a multi-gang frame. You can flexibly fix the mounting plate (F) to the wall using adhesive strips or screws. For mounting with multi- ple combinations, make sure that the mounting plate of the wall thermostat is seamlessly aligned to the already fixed mounting plate/retaining ring. The wall thermostat is designed to fit into frames supplied by the following manufacturers: Manufacturer Frame Berker S.1, B.1, B.3, B.7 glass ELSO Joy GIRA System 55, Standard 55, E2, E22, Event, Esprit merten 1-M, Atelier-M, M-Smart, M-Arc, M-Star, M-Plan JUNG A 500, AS 500, A plus, Acreation 7 Operation After configuration, simple operations are available directly on the device. If the wall 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. In automatic mode, the ma- nually set temperature will remain the same until the next point at which the schedule changes. After- wards, the defined heating sche- dule will be activated again. During manual operation, the temperature remains activated until the next manual change.

There will be a pleasant room temperature right away be- cause of the radiated heat.24 Changing the batteries 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 LR03/micro/AAA batteries. You must observe the correct battery polarity. To replace the batteries of the wall thermostat, please proceed as follows:

• Once mounted, the electronic unit (B) can easily be pulled out of the frame (A) and removed from the mounting plate (F). To remove the electronic unit from the frame, take hold of the sides of the electronic unit and pull it out (see figure). You do not need to open the de- vice.

• Turn the electronic unit over to re- move or insert the batteries.

• Insert two new 1.5 V LR03/micro/ batteries into the battery compart- ment, making sure that you insert them the right way round.

Put the electronic unit back into the frame. Make sure that “TOP” and the arrows on the back side of the electronic unit point upwards and that the clips on the mounting plate latch into the openings on the electronic unit.

• Please pay attention to the flashing signals of the device LED while in- serting the batteries (see „9.4 Error codes and flashing sequences“ on page 26). Once the batteries have been inser- ted, the wall thermostat will perform a self-test/restart (approx. 2 seconds). Afterwards, initialisation is carried out. The test display will indicate that initia- lisation is complete: orange and green lighting.25 Troubleshooting 9 Troubleshooting

Provided that the voltage value per- mits it, the wall thermostat will remain ready for operation also 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 sequences“ on page 26). In this case, replace the empty batteries by two new batteries (see „8 Changing the batteries“ on page 24).

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 failed transmis- sion may be caused by radio inter- ference (see „12 General information about radio operation“ on page 28). This may be caused by the following:

• Receiver cannot be reached.

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

The duty cycle is a legally regulated li- mit of the transmission time of devices in the 868 MHz range. The aim of this regulation is to safeguard the opera- tion 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 se- conds in an hour). Devices must cease transmission when they reach the 1% limit until this time restriction comes to an end. HomematicIP devices are de- signed and produced with 100% con- formity 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 is exceeded, this is indicated by three slow flashes of the device LED, and may manifest itself in the device temporarily working incorrectly. The device starts working correctly again after a short period (max. 1 hour).26 Troubleshooting

• Press and hold down the system button again for 4 seconds, until the LED lights up green.

• Release the system button again to conclude the procedure. The device will perform a restart. 11 Maintenance and cleaning The device does not require you to carry out any maintenance other than replacing the battery when necessary. Enlist the help of an expert to carry out any mainte- nance or repairs. Clean the device using a soft, lint-free cloth that is clean and dry. You may dampen the cloth a little with luke- warm water in order to remove more stubborn marks. Do not use any de- tergents containing solvents, as they could corrode the plastic housing and label.28 General information about radio operation 12 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 ope- rations, electrical motors or defective electrical devices. The range of transmission within buildings can dier greatly from that available in the open air. Besi- des the transmitting power and the reception characteristics of the receiver, environmental fac- tors such as humidity in the vicini- ty have an important role to play, as do on-site structural/screening conditions. eQ-3 AG, Maiburger Straße 29, 26789 Leer, Germany hereby declares that the radio equipment type HomematicIP HmIP-WTH-1, HmIP-WTH-A is compli- ant with Directive 2014/53/EU.
