Product information

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.

Suitable for

  • Room temperature control in apartments, houses, and small offices
  • Retrofit smart-home upgrades without new wiring
  • Integration with Homematic IP radiator thermostats and heating schedules
  • Applications where compact dimensions and discrete appearance are required

Key specifications

  • Wireless interface: RF, 869.65 MHz
  • Display type: LCD
  • Power supply: single 1.5 V battery
  • Estimated battery life: up to 5 years under typical use
  • Housing colour: anthracite
  • Dimensions: 85 × 85 × 22 mm

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. Insert the 1.5 V battery and follow the Homematic IP pairing procedure to register the device in your Homematic IP access point or gateway. Configure setpoints and weekly schedules via the Homematic IP app or central control unit; the thermostat will measure room temperature and transmit control commands to paired radiator actuators according to the programmed schedule. For battery replacement, remove the cover, fit a fresh 1.5 V battery, and re-pair if required by the system.

Usage recommendations

Install the thermostat at a representative location within the room—avoid placement above radiators, near windows, or directly behind curtains. Use the Homematic IP app to create time-based heating schedules and to group the thermostat with radiator valves for coordinated temperature control and energy-efficient operation.
