4 Function and device overview

The Homematic IP Wall Thermostat offers time-controlled regulation of floor heating systems in connection with Homematic IP Floor Heating Actuators or conventional radiators using Homematic IPRadiatorThermostats according to individually tailored heating phases. The wall thermostat serves to measure the temperature and humidity in a room. The data is cyclically transmitted to a floor heating actuator or radiator thermostats in order to regulate the room temperature precisely. You can pair the wall thermostats with a Homematic IP CCU3 or connect it to the Homematic IP access point in order to control the device comfortably via the Homematic IP app. Thanks to battery operation, the device is highly flexible where mounting and selecting a mounting location are concerned. The device is mounted and removed very easily with the supplied clip-on frame using screws or adhesive strips. It is compatible with a number of different surfaces including furniture, brick walls, tiles or glass. It is also possible to integrate the wall thermostat into existing switches.

- 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 inserting the batteries (see „9.4 Error codes and flashing sequences“ on page 26).

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

9 Troubleshooting

9.1 Low 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 (a) 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 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 „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.).
• Receiver is faulty.

9.3 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 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).

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 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.

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 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, Maiburger Straße 29, 26789 Leer, Germany hereby declares that the radio equipment type Homematic IP HmIP-WTH-1, HmIP-WTH-A is compliant with Directive 2014/53/EU. The full text of the EU declaration of conformity is available at the following internet address:
