7 Replacing 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 6). You do not need to open the device.
• Turn the electronic unit over to remove or insert the batteries.
• Insert two new 1.5 V LR03/micro/batteries into the battery compartment, making sure that you insert them the right way round (see figure 7).
• Put the electronic unit 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.
• Please pay attention to the flashing signals of the device LED while inserting the batteries (see "8.4 Error codes and flashing sequences" on page 45).

Once the batteries have been inserted, the wall thermostat will perform a self-test/restart (approx. 2 seconds). Afterwards, initialisation is carried out. The LED test display will indicate that initialisation is complete by lighting up orange and green.

Never recharge standard 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.

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

8 Troubleshooting

8.1 Weak battery

Provided that the voltage value permits it, the wall thermostat will remain ready for operation also if the battery 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 empty battery symbol (☐) and the corresponding error code will be displayed on the device (see „8.4 Error codes and flashing sequences" on page 45). In this case, replace the empty batteries by two new batteries (see „7 Replacing batteries" on page 42).

8.2 Command not confirmed

If at least one receiver does not confirm a command, the device LED 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 48). This may be caused by the following:

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

8.3 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 teach-in 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).

  • Release the system button again.
• Press and hold down the system button again for 4s, until the status LED lights up green.
• Release the system button to finish the procedure.

The device will perform a restart.

10 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 maintenance or repairs.

Clean the device using a soft, lint-free cloth that is clean and dry. You may dampen the cloth a little with lukewarm water in order to remove more stubborn marks. Do not use any detergents containing solvents, as they could corrode the plastic housing and label.

11 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.

eQ-3 AG hereby declares that this device complies with the essential requirements and other relevant regulations of Directive 1999/5/EC.
