Thermostat Homematic IP HMIP-ETRV-B RF White 153412A0

The Homematic IP Radiator Thermostat (HMIP-ETRV-B, MPN 153412A0) is a wireless radiator thermostat for smart home heating control. It replaces manual radiator valves and integrates with the Homematic IP system using RF communication to provide precise room temperature regulation and support for energy-saving schedules. The device fits standard M30 valve threads and includes adapters for Danfoss valves. It is battery powered (two AA) and designed for simple installation without intervention in the heating system.

Advantages

The thermostat supports up to three configurable week profiles with up to six heating phases per day, enabling automated temperature changes for different times and days. When combined with the Homematic IP Window/Door Contact the device automatically reduces radiator output if a window is opened, and restores heating when the window is closed. Secure mounting is achieved via a metal union nut, and the low-noise gearbox makes it suitable for living rooms, bedrooms and children's rooms. Manual controls on the device allow direct temperature adjustment and activation of a boost function for rapid heating. Additional functions include limescale and frost protection to safeguard the valve.

Suitable for

• Replacing manual radiator thermostats with M30 valve threads
• Integration into Homematic IP smart home heating systems
• Rooms requiring scheduled temperature control (bedrooms, living rooms, bathrooms)

How to use

Install the thermostat on a radiator valve with M30 thread by securing it with the supplied metal union nut or the included Danfoss adapter if required. Insert two AA batteries and add the device to the Homematic IP system via the app or wall thermostat following the manufacturer’s pairing instructions. Configure up to three week profiles and define heating phases as needed. Temperature can be adjusted directly on the device, via the Homematic IP Wall Thermostat or within the Homematic IP app. When paired with a Homematic IP Window/Door Contact, the thermostat will reduce heating automatically when a window is open.

Usage recommendations

For best energy savings, combine the radiator thermostat with Homematic IP window/door contacts and create dedicated week profiles for typical daily routines; ensure batteries are replaced before depletion and verify valve compatibility during installation.
