Bosch Smart Home Raumthermostat II 230 V - Zigbee Room Control For Wired Heating

Bosch Smart Home Raumthermostat II 230 V is designed to bring smart, app based control to wired heating systems such as hydronic floor heating and central heating, combining an in wall thermostat unit with Zigbee radio and Bosch Smart Home app integration.

Design, Power And Core Specs

The Bosch Smart Home Raumthermostat II 230 V is built as a compact wall mounted room thermostat with housing dimensions of 86 x 87 x 35 mm and a weight of 131 g, making it suitable for standard flush mounted switch boxes in residential installations.Housing dimensions and weight The thermostat operates on a 230 V AC mains supply, using phase and neutral conductors at the device for power, and is designed for fixed installation in flush mounted boxes with a minimum depth of 35 mm.230 V power and installation depth For radio communication, it uses ZigBee 3.0 in the 2.4-2.4835 GHz band, matching other Bosch Smart Home components for wireless device integration.ZigBee 3.0 radio protocol

The thermostat measures room temperature and relative humidity at the mounting location, and it presents this information on an LCD display with room temperature as the primary readout.Room temperature and humidity display It is rated for indoor use with IP21 protection, with an operating ambient temperature range of 0-50 °C and maximum relative humidity of 80% non condensing, which fits typical home environments.IP21 rating and ambient conditions

Smart Functions, App Control And Compatibility

In a Bosch Smart Home setup, the Raumthermostat II 230 V connects via ZigBee to a Bosch Smart Home Controller and is configured through the Bosch Smart Home app, which is required for adding the thermostat as a device and defining its heating role.Smart Home Controller and app requirement Once integrated, the thermostat supports central heating control by acting as the controller for a heating generator when the device type is set to "Zentralheizung" in the app and the central heating service is activated in the climate manager section.Central heating service configuration

The thermostat integrates with Bosch Smart Home heating devices, including floor heating actuators and heating circuits, and it can be used for wired systems such as hydronic floor heating to make them controllable by schedules, remote app commands, and voice integration via smart assistants connected to the Bosch Smart Home system.Wired heating compatibility The device offers additional smart features such as child lock and window open detection when incorporated into a broader climate management scene, enhancing safety and energy efficiency.Child lock and window open detection

Comparison With Battery Powered Raumthermostat II

Compared with the battery powered Bosch Raumthermostat II, which uses a 6 V DC supply from four AAA batteries and includes a stand for flexible placement in the room, the 230 V version is wired into the wall and relies on mains power rather than replaceable cells.Battery powered Raumthermostat II specifications The battery model weighs 112 g and can be used free standing or wall mounted with an included stand and wall mounting set, whereas the 230 V version is intended for fixed flush mounted installation and serves especially wired floor heating and central heating use cases.Weight and mounting accessories

Functionally, the 230 V thermostat is tailored to cable bound heating applications and can act as a central controller for a boiler or heater when combined with the Bosch Smart Home Controller, while the battery operated Raumthermostat II focuses on wireless control of radiator thermostats and portable placement in the room.Portable Raumthermostat II description For households choosing between the two, the 230 V model aligns with permanent installations in wired systems, while the battery version addresses flexible placement for radiator based heating.

Position In The Smart Heating Segment

Within smart heating solutions, Bosch Smart Home Raumthermostat II 230 V occupies the niche of Zigbee based, app connected control for wired hydronic and central heating systems, offering compact dimensions, 230 V mains operation, and integration into Bosch climate management scenes rather than standalone operation.Segment placement It is not compatible with Bosch EasyControl, so it fits best in homes that already use or plan to use the Bosch Smart Home Controller and related Zigbee devices for coordinated climate control.EasyControl incompatibility and Smart Home focus
