Product information

Description

Homematic IP HmIP-WTH-2 is a wall-mounted room thermostat designed for integration into EQ3-AG smart heating systems. The compact white casing (86×86×25 mm) houses a battery-powered controller that operates on the 868.3 MHz frequency and runs from standard AAA batteries, offering a simple wired-free installation for homes and small offices. Typical power consumption is 50 mA, and the device provides temperature regulation and setpoint control for connected heating actuators within a Homematic IP environment.

Advantages

The thermostat combines compact dimensions with wireless operation, allowing flexible placement without additional wiring. Operating at 868.3 MHz ensures compatibility with Homematic IP networks and reliable radio communication. Battery power simplifies installation and replacement, while a built-in memory function preserves user settings after power changes. The neutral white color and slim profile suit a variety of interior styles and mounting locations.

Suitable for

  • Room temperature control in apartments and houses
  • Small office climate regulation
  • Integration into Homematic IP smart heating systems
  • Retrofit projects where wiring is limited or not desired

Key specifications

  • Radio frequency: 868.3 MHz
  • Power supply: AAA batteries (1.5 V)
  • Typical power consumption: 50 mA
  • Dimensions: 86 × 86 × 25 mm
  • Color: white
  • Memory function: preserves settings after power interruption

How to use

Mount the thermostat on an interior wall at a representative room height, avoiding direct sunlight and drafts. Insert fresh AAA batteries and follow the Homematic IP pairing procedure to add the device to the controller or access point. Use the device controls or the Homematic IP app to set target temperatures and schedules; the thermostat communicates setpoints wirelessly to compatible heating actuators. Replace batteries when indicated to maintain reliable operation.

Usage recommendations

Place the thermostat on an inner wall away from heat sources, windows and doors to ensure accurate temperature measurement. For battery life optimization, use moderate temperature schedules and check the device state periodically in the Homematic IP interface. When retrofitting older installations, verify actuator compatibility before installation.

Backlight display: A backlight is a form of illumination used in liquid crystal displays (LCDs). As LCDs do not produce light themselves - unlike for example Cathode ray tube (CRT) displays - they need illumination (ambient light or a special light source) to produce a visible image. Backlights are used in small displays to increase readability in low light conditions such as in watches, and in computer displays and LCD televisions to produce light in a manner similar to a CRT display.

International Protection (IP) code: The IP code classifies and rates the degree of protection provided against the intrusion (including body parts such as hands and fingers), dust, accidental contact, and water by mechanical casings and electrical enclosures. It is published by the International Electrotechnical Commission (IEC). The digits (characteristic numerals) indicate conformity with the conditions summarized in the tables below. Where there is no protection rating with regard to one of the criteria, the digit is replaced with the letter X. an electrical socket rated IP22 is protected against insertion of fingers and will not be damaged or become unsafe during a specified test in which it is exposed to vertically or nearly vertically dripping water. Another example is the Sony Xperia Z Ultra, one of the first cellular phones to be IP-rated; it is rated at IP58 and marketed as "dust resistant" and can be "immersed in 1.5 meter of freshwater for up to 30 minutes".
