Termostato de pared de cristal Homematic IP 161333A0 con sensor de CO2, RF digital, 230 V, 54,5×54,5×29 mm

The Homematic IP glass wall thermostat 161333A0 with integrated CO2 sensor is a digital room controller designed for 230 V AC mains (50 Hz). Housed in a compact white glass casing (54.5 × 54.5 × 29 mm), the device measures ambient temperature, relative humidity and CO2 concentration, and provides a touch-operated display for direct control. With an RF interface for wireless communication, it can be used alone to control 230 V drive valves or loads via the integrated relay output and can be integrated into a Homematic IP system for coordinated climate and ventilation control.

Advantages

The glass surface offers a durable, easy-care finish that is resistant to everyday wear and provides hygienic, non-porous operation. Integrated sensors present current temperature, humidity and CO2 values on the display for continuous monitoring. The built-in relay output enables direct control of 230 V drive valves—suitable for underfloor heating or for switching lighting and other loads—while the RF interface allows seamless integration with other Homematic IP components for automated scenarios. The compact dimensions and white design allow unobtrusive installation in residential and commercial interiors.

Suitable for

• Room temperature control for underfloor heating and conventional radiators
• Automated ventilation strategies based on CO2 and humidity levels
• Integration into Homematic IP systems for coordinated heating, ventilation and lighting control
• Direct switching of 230 V drives and loads via the integrated relay output

Key specifications

• Power supply: 230 V AC, 50 Hz
• Measured parameters: ambient temperature, relative humidity, CO2 concentration
• Control output: integrated relay for 230 V loads and drive valves
• Communication: RF wireless interface for Homematic IP integration
• Housing: white glass surface, dimensions 54.5 × 54.5 × 29 mm
• User interface: touch-operated display showing temperature, humidity and CO2

How to use

Install the thermostat on a standard switch mounting box following local electrical regulations and connect mains and load conductors to the relay output as required. Use the touch surface to set the desired room temperature and view current humidity and CO2 readings directly on the display. For extended functionality, add the device to a Homematic IP access point or bridge using the RF interface to configure schedules, scenes and linked devices in the Homematic IP app. The relay output can be assigned to control 230 V drive valves for heating or to switch lighting and other appliances.

Recommendations

Mount the thermostat at typical room height away from direct sunlight, doors, windows and local heat sources to ensure representative temperature, humidity and CO2 readings. Use the Homematic IP app to create ventilation or heating schedules based on measured CO2 and humidity values to maintain indoor air quality efficiently. When controlling 230 V drives, verify compatibility of valves and loads with the relay ratings and follow wiring instructions by a qualified electrician.
