3 Function and device overview

The Homematic IP Wall Thermostat with switching output – for brand switches offers a relay output for controlling 230 V floor heating valve drives.

By controlling the relay output the room temperature is regulated according to your individually defined heating profiles.

Furthermore, the Homematic IP Wall Thermostat can be used in connection with the Homematic IP Floor Heating Actuator or Homematic IP Radiator Thermostat for conventional radiators and thus offers a demand-based room-by-room temperature control.

The wall thermostat measures the temperature and humidity in the room and controls the relay output based on the current values. Controlling commands and configuration can be realised directly on the Homematic IP Wall Thermostat or comfortably via the free Homematic IP app.

You can simply replace the existing wall thermostat of your installation by the Homematic IP Wall Thermostat and install the device in the flush-mounting box.

Using the components of existing or planned switches and cabling reduces the installation costs to a minimum. The design, colour and finish of switches that have already been installed does not change, since existing frames can continue to be used.

There will be a pleasant room temperature right away because of the radiated heat. *The boost function can only be executed in connection with a Homematic IP Radiator Thermostat.

8 Troubleshooting

8.1 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 84). 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.

8.2 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 (D), and may manifest itself in the device temporarily working incorrectly. The device starts working correctly again after a short period (max. 1 hour).

The factory settings of the device can be restored. If you do this, you will lose all your settings.

To restore the factory settings of the wall thermostat, please proceed as follows:

- Pull the electronic unit (B) forward (see fig. 7).

- Place the electronic unit back on the voltage supply unit (F) and press and hold down the system button (D) for 4 seconds (see fig. 5) at the same time, until the LED will quickly start flashing orange.

- Release the system button again.

- Press and hold down the system button again for 4 seconds, 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. You can find the full declaration of conformity at www.eQ-3.de.
