## Long description

The Homematic IP HmIP-WTH-B-A room thermostat is a compact wall-mounted device for wireless temperature measurement and control in residential and small commercial heating systems. Operating on the 869.65 MHz RF band, the thermostat communicates with Homematic IP radiator actuators and other system components to implement setpoints and schedules. The unit features an LCD for clear readout, an anthracite housing that suits modern interiors, and is powered by a single 1.5 V battery with an estimated service life of up to five years. With dimensions of 85 × 85 × 22 mm, the thermostat is suitable for retrofit installation and for positioning at any location in the room to ensure precise local temperature sensing.
Advantages
The thermostat provides wireless control via the 869.65 MHz RF interface, enabling integration into Homematic IP smart-home networks without additional wiring. The LCD offers legible temperature and status information, while the compact, low-profile design simplifies placement and retrofit mounting. Long battery life reduces maintenance intervals, and the anthracite finish delivers a neutral, unobtrusive appearance that fits most interiors. By supplying accurate room temperature data and transmitting control commands to radiator valves, the device helps implement timed heating profiles and supports energy-efficient operation.

How to use
Mount the thermostat on an interior wall at typical room height away from direct sunlight, drafts, or heat sources for representative temperature readings.
