## Long description

Homematic IP 159928A0 is a digital room thermostat in anthracite with an LED display and mains power (230 V AC, 50 Hz). Designed for setpoint regulation of radiators and underfloor heating, it communicates on 869.65 MHz and integrates into Homematic IP smart‑home networks. The device has compact dimensions (86×86×54 mm) and provides a switching output for direct control of heating actuators, enabling conversion of conventional wall thermostats to smart control without extensive rewiring.
Advantages
The thermostat offers straightforward retrofit installation by replacing an existing wall thermostat and supports both stand‑alone operation and integration into a Homematic IP system. Mains power ensures continuous operation without battery changes, while the LED display provides clear indication of setpoint and status. Communication at 869.65 MHz allows stable wireless connection within Homematic IP networks, and the compact anthracite housing fits standard 86 mm installation frames.
Suitable for
 Retrofitting conventional wall thermostats to smart control

How to use
Replace your existing wall thermostat with the Homematic IP 159928A0 following local electrical safety rules and turning off mains supply before installation. Connect the thermostat to the mains and to the heating actuator using the switching output according to the installation instructions. After power‑up, configure the setpoint and schedules either directly on the device via the LED display or by adding the device to the Homematic IP system using the app for remote scheduling and zoning. For systems without a Homematic IP access point, the thermostat can operate in a basic stand‑alone mode to control temperature locally.
Usage recommendations
Use the thermostat with compatible heating actuators and ensure wiring is carried out by a qualified electrician. For full smart functionality, add the device to a Homematic IP access point and configure heating schedules and geofencing in the app. Avoid locating the thermostat near direct heat sources or drafts to ensure accurate room temperature measurement.
