## Long description

The Homematic IP HMIP-WTH-B wired thermostat is designed for indoor wall mounting and offers temperature and humidity control for heating systems. It features an RF interface and a backlit LCD for clear display of setpoint and actual temperatures. Operating on 24 V with a 1 A current rating and IP20 protection, the compact white housing (55×55×54 mm) fits into standard flush-mounted boxes and multi-gang frames from common manufacturers.
Advantages
The thermostat provides precise manual control via a rotary control wheel with 0.5 °C resolution and supports up to six adjustable heating and cooling profiles with multiple daily switching times for demand-based regulation. Integrated measurement and display of room temperature and humidity on a large illuminated LCD help monitor conditions at a glance. The device supports direct setup and configuration of floor heating actuators without requiring a central unit, while RF connectivity enables integration into Homematic IP systems and third‑party partner solutions.
Suitable for
Replacing existing wall thermostats in residential or small commercial indoor spaces
Controlling conventional floor heating systems
Integration into Homematic IP smart home setups with or without an Access Point
Installation into standard flush-mounted boxes and multi-gang frames

How to use
Install the thermostat in an existing flush-mounted box and connect it to a 24 V supply following local electrical regulations. Use the rotary control wheel to set the desired temperature in 0.5 °C increments and read actual temperature and humidity on the LCD. Configure heating or cooling profiles directly on the device: select one of the available profiles, define phases and switching times, and save settings. For integration into a Homematic IP system, pair the device via RF with an Access Point, CCU2, or supported partner solution; alternatively, configure compatible floor heating actuators directly from the thermostat without a central unit.
Usage recommendations
Place the thermostat on an interior wall away from direct sunlight, drafts and heat sources for accurate temperature measurement. Observe installation guidelines and local wiring standards; if unsure, engage a qualified installer. Use the programmable profiles to match daily occupancy patterns and reduce energy consumption by lowering setpoints during unoccupied periods.
