Glass wall thermostat Homematic IP model 161458A0 — digital, white, 230 V, IP20

Homematic IP Glass wall thermostat model 161458A0 is a digital, wall-mounted room thermostat with a white glass front, designed for 230 V AC systems. The device provides precise temperature and humidity indication on an integrated display and offers direct control of 230 V drive valves or other loads via an integrated relay output. With IP20 protection and a compact design, the thermostat is intended for indoor installation and can be integrated into compatible Homematic IP smart-home systems for central or zoned climate control.

Advantages

The glass surface combines a modern look with a durable, easy-care finish that resists everyday wear. Sensitive touch controls and a discreet display allow intuitive on-device operation, while wireless connectivity enables remote configuration and automation through compatible Homematic IP components. Direct relay control of 230 V actuators or loads adds installation flexibility for underfloor heating, radiators with motorised valves, electric heaters or lighting circuits.

Suitable for

• Wall-mounted temperature control of underfloor heating circuits
• Direct control of 230 V drive valves and electric heaters
• Integration into Homematic IP smart-home setups for zoned climate control
• Rooms where a compact, stylish thermostat with humidity display is required

Key specifications

• Supply voltage: 230 V AC, 50 Hz
• Protection class: IP20 for indoor installation
• Front material: white glass with touch-sensitive control surface
• Integrated display: room temperature and relative humidity indication
• Output: relay for switching 230 V actuators or loads

How to use

Mount the thermostat on a standard indoor wall connection suitable for 230 V devices and connect the supply and relay output according to the installation wiring diagrams provided by the manufacturer. Use the touch surfaces to set the desired temperature directly on the device or configure schedules, setpoints and groupings via the Homematic IP app and compatible central units. The display shows current room temperature and humidity for verification of settings, and relay output can be assigned to drive valves, electric heaters or lighting circuits as required.

Recommendations

Install the thermostat at a representative height on an interior wall away from direct sunlight, drafts, windows and heat sources to ensure accurate temperature measurement. Use the Homematic IP app or a compatible central control device to create heating schedules and zone configurations for energy-efficient operation. For installations controlling high inrush loads or non-resistive loads, verify that the connected actuator or load is suitable for direct switching by the thermostat relay or use an appropriate intermediate relay or contactor.
