Glass wall thermostat Homematic IP 161570A0 — digital, black, 230 V, IP20

Homematic IP Glass wall thermostat 161570A0 is a digital room thermostat with a black glass front designed for wall mounting. The device operates on 230 V AC (50 Hz) and is rated IP20 for indoor use. Compact and lightweight, it provides precise temperature control for heating systems and room climate regulation in homes and offices. The glass surface incorporates touch-sensitive controls and a discrete integrated display that shows current room temperature and relative humidity.

Advantages

The glass front offers a durable, easy-care surface that retains a high‑quality appearance over time and is suitable for frequent use. Precise temperature measurement and an integrated relay output allow direct control of 230 V drive valves or alternative loads such as lighting. The thermostat supports local touch control and can be integrated into a Homematic IP system for scheduling and remote operation, enabling individualized climate control for separate zones.

Suitable for

• Underfloor heating systems with 230 V drive valves
• Conventional radiators with electric drive valves
• Electric heaters and direct 230 V loads such as lighting
• Residential rooms and office spaces where a compact, wall‑mounted thermostat is required

How to use

Mount the thermostat on a suitable interior wall at typical sensor height, avoiding direct sunlight, drafts and heat sources for accurate measurements. Connect the device to the 230 V supply and wire the relay output to the intended 230 V drive valve or load following applicable electrical regulations. Use the touch-sensitive surface to set the desired temperature directly on the unit. When integrated into a Homematic IP system, use the app to configure schedules, link with other Homematic IP devices and adjust settings remotely.

Recommendations

For reliable temperature sensing, install the thermostat on an interior wall away from windows, radiators and doors. Use the Homematic IP app to create heating schedules for different zones and to combine the thermostat with radiator thermostats or switching actuators for energy-efficient climate control. Ensure electrical connections are performed by a qualified electrician and follow local safety standards.
