Function
In connection with Homematic Wireless Radiator Thermostats (HM-CC-RT-DN), the Homematic Wireless Room Thermostat can conveniently regulate the room temperature according to individually tailored heating phases. The room thermostat measures the temperature and humidityand cyclically transmits the data to the radiator thermostat to regulate the room temperature. With the boost function, radiators can be heated up quickly and briefly. There will be a pleasant room temperature right away because of the radiated heat.
General information about the Homematic system
This device is part of the Homematic home control system and works with the bidirectional Homematic wireless protocol. All devices are delivered in a standard configuration. The functionality of the device can also be configured with a programming device and software. The additional functions that can be made available in this way and the supplementary functions provided by the Homematic system when it is combined with other components are described in the Homematic WebUI Manual. You can find the latest versions of all technical documents and the latest updates at: www.homematic.com
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 be caused by e.g. 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.
Hereby, eQ-3 AG declares that this device conforms with the essential requirements and other relevant regulations of Directive 1999/5/EC. The full declaration of conformity is provided under www.homematic.com.
