## Long description

Homematic IP HMIP-ETRV-B is a battery-powered room radiator thermostat with an RF interface operating at 868.3 MHz and a clear digital display. Designed for integration into Homematic IP smart home systems, the compact white unit (58 × 71 × 97 mm) runs on two AA 1.5 V batteries and supports practical heating control in apartments and houses. It replaces conventional radiator valves without intervention in the heating system and enables scheduled temperature control, manual operation at the device and remote control via the Homematic IP app or compatible wall thermostats.
Advantages
The thermostat offers energy-saving operation by enabling automated temperature profiles and interaction with other Homematic IP components. Installation is simple: the metal union nut fixes the device to standard M30 valve connections and supplied adapters cover common valve types. Low-noise gearing makes it suitable for living and sleeping areas, while integrated limescale and frost protection safeguard the valve. Long battery life and a readable digital display allow convenient local control and status checks.
Suitable for
Individual radiators with M30 valve connections (adapters included for common valve types)
Homes and apartments seeking programmable room heating control
Integration into Homematic IP systems for app-based and automated control
Rooms where quiet operation is required, such as bedrooms and children's rooms

How to use
Mount the thermostat onto the radiator valve using the metal union nut; use the supplied adapters for alternative valve types if required. Insert two AA batteries and follow the Homematic IP app or device instructions to add the thermostat to your Homematic IP system. Set desired room temperatures directly on the device, via a Homematic IP Wall Thermostat, or in the app. Define up to three weekly profiles with up to six heating phases per day to automate heating. When paired with a Homematic IP Window/Door Contact, the thermostat will reduce heating automatically if a window is detected open and restore the temperature after the window is closed.
Usage recommendations
For reliable battery life and consistent operation, use high-quality AA batteries and check device status periodically in the Homematic IP app. Place the thermostat on radiators that allow free airflow and avoid covering the unit or mounting it behind large objects; if multiple thermostats are used in one room, manage them centrally via the app or a Homematic IP Wall Thermostat to prevent conflicting control.
