## Long description

The eQ-3 AG HmIP-WTH-B RF White wall thermostat enables intelligent temperature control in a room either via smartphone app, voice assistants or directly on the device. It supports control of multiple radiator thermostats or underfloor heating circuits within the same room. The thermostat has an analogue LC display, runs on AA batteries (1.5 V) and communicates wirelessly with compatible Homematic IP systems for seamless smart‑home integration.
Advantages
The device allows creation of individual temperature profiles with up to three configurable heating programs and 13 time changes per day. Temperature is regulated automatically and only when required; setpoints can be adjusted in 0.5 °C steps using push‑buttons. A boost function provides rapid temporary heating. The thermostat measures room temperature and humidity and transmits these values to radiator thermostats and the Homematic IP app so current conditions are always visible on the display or in the app. Battery operation and radio communication enable simple retrofit installation without wiring.
Suitable for
Control of radiator thermostats in living rooms, bedrooms and offices
Management of one or several floor‑heating circuits in a single room
Retrofit smart control of conventional electric radiators when used with a switch actuator
