Vaillant sensoHOME 380f - wireless digital thermostat

Product detailed description

Vaillant sensoHOME 380f - wireless digital thermostat with weekly program for one heating circuit

Vaillant sensoHOME 380f is a modern wireless (radio) room thermostat designed to control one direct heating circuit without the need to run a communication cable between the boiler room and the living room. The device communicates with a radio receiver connected to the boiler via a bidirectional radio signal, making installation quick, clean and without the need to interfere with building structures - an ideal solution for apartment renovations, heritage-protected buildings, or anywhere additional cable routing would be impractical or costly.

Unlike the simple wired VRT 50 thermostat, the sensoHOME 380f offers its own weekly time program directly in the device, a large, clear backlit display with touch or intuitive controls, and the option of expansion with other system components - for example an outdoor temperature sensor for more precise weather-compensated control, or the VR 92f module for controlling another separate heating zone (for example in an apartment building where several housing units need to be controlled separately from a single heat source).

Main technical features

• Wireless (radio) communication between the thermostat and the receiver connected to the boiler - bidirectional data transfer including feedback on the boiler's operating status.
• Its own weekly heating time program with the option of setting different temperature levels for individual days and time periods (weekdays / weekend, or hourly blocks depending on the firmware model).
• Large, clear, backlit display showing current and desired temperature, day of the week and operating mode.
• Modulating control of boiler output based on the actual temperature in the reference room instead of simple on/off switching.
• Support for an adaptive heating curve - the system gradually "learns" the thermal inertia of the building and optimizes the heating start time so that the desired temperature is reached exactly at the scheduled time.
• Option to connect an optional outdoor temperature sensor for more precise weather-compensated control (compensation based on outdoor temperature).
• Option of expansion with the VR 92f module for controlling another separate heating circuit/zone.
• Support for a holiday (setback) mode function and the option of remote control via internet gateway and the myVaillant mobile app, if installed.
• Battery-powered with long battery life thanks to an economical radio protocol.

Compatibility

The sensoHOME 380f is designed for one direct (unmixed) heating circuit and works with Vaillant boilers equipped with a radio receiver for wireless communication (included in delivery or purchased separately depending on the specific installation). The system is part of the sensoHOME family, which follows on from the older VRT 380f family, and is fully compatible with the current generation of Vaillant ecoTEC condensing boilers. For apartment buildings or houses with multiple heating zones, we recommend combining it with the VR 92f module, which allows adding another independent circuit controlled by a separate thermostat.

If the system also includes a heat pump or a hybrid solution (boiler + heat pump), we recommend verifying the compatibility of the specific combination with our technical team, as some hybrid installations require a higher-level system controller (such as multiMATIC or sensoCOMFORT) instead of a standalone room thermostat.

Installation and commissioning

Installation of the sensoHOME 380f consists of three steps: mounting the radio receiver on the boiler (connecting to the communication terminals of the control electronics), placing the thermostat itself in a suitable location in the reference room (on the wall using the supplied mounting plate, or freestanding on a table/shelf using a stand, if the device supports it), and finally pairing the thermostat with the receiver via a simple process described in the manual (usually by pressing a button on both devices within a short time window).

After pairing, the current date and time are set, the type of control is selected (two-point/modulating), and the weekly heating schedule is programmed according to the needs of the household. We recommend placing the thermostat in a room that best represents the average temperature of the living space, away from direct sunlight, drafts from windows and doors, and other heat sources.

We recommend leaving the initial commissioning, especially setting the boiler parameters for cooperation with the wireless thermostat and connecting any outdoor sensor or the VR 92f module, to a qualified service technician.

Typical use cases

The sensoHOME 380f is a suitable choice especially for renovations where there is no route available for laying a communication cable between the boiler and the living room, or where such a route would be impractically expensive (e.g. multi-storey houses, apartments in buildings with strict rules for construction modifications). The thermostat is also a popular choice when modernizing an older installation with an outdated wired thermostat, where the investor wants to gain weekly programming and better comfort without interfering with the electrical wiring.

Thanks to the option of expansion with the VR 92f module, the sensoHOME 380f is also suitable for smaller apartment buildings or two-generation houses, where two separate apartments or zones with different heating modes need to be controlled independently from a single heat source.

Why choose the sensoHOME 380f

The main advantage of the sensoHOME 380f is the combination of simple, cable-free installation with full weekly programming and modulating boiler output control. Compared to cheaper simple radio thermostats without a link to the boiler's control electronics, the sensoHOME 380f provides bidirectional communication, meaning more precise control, lower fuel consumption thanks to smooth output modulation, and the ability to display boiler operating states and any faults directly on the thermostat's display.

The adaptive heating curve also ensures that the house reaches the desired temperature exactly at the scheduled time, without unnecessary premature or delayed start of heating, which saves energy and costs over the long term.

Maintenance and care

The sensoHOME 380f thermostat does not require complex maintenance - it is recommended to regularly check the battery status (the device usually indicates a low battery with an icon on the display) and replace the batteries with new alkaline batteries of the recommended type when necessary. Clean the display and casing with a slightly damp cloth without using solvents. If the radio connection with the receiver is lost, check the distance and obstacles between the thermostat and the receiver (thick concrete walls, metal structures or other radio devices can cause interference) - if necessary, a VR 52 signal booster can be added to extend the range.

Frequently asked questions (FAQ)

Why wireless communication instead of a cable

The wireless solution brings several practical advantages, especially for renovations and modernizations of older buildings. There is no need to break through plaster, cut grooves, or run cable trunking across rooms, which saves time and construction costs while preserving the interior's aesthetics. The thermostat can also be easily relocated to another spot in the room if it turns out over time that the original position is not optimal (for example, it is exposed to direct sunlight during summer months, which can distort the measurement during transitional periods). The radio protocol used in the sensoHOME 380f is also bidirectional - the thermostat not only sends the desired temperature but also receives feedback on the current status of the boiler, any faults and service messages, which are then displayed directly on the thermostat's display without having to go to the boiler.

Energy savings in practice

The combination of the weekly program, modulating control and adaptive heating curve brings real energy savings compared to older simple thermostats or manual control directly on the boiler. The heating system does not switch on and off abruptly but smoothly adapts its output to the current heat loss of the building, preventing unnecessary overheating as well as excessive cooling between cycles. Setting a lower temperature during absence (for example during a workday or at night) and a scheduled rise to comfort temperature just before arriving home or waking up brings savings that can be noticeably reflected in gas or other fuel bills over the course of a heating season, depending on the specific type of heat source and the building's thermal insulation properties.

Difference from the older VRT 380f generation

The sensoHOME family follows on from the older generation of wireless thermostats VRT 380f and brings a more modern display, improved control ergonomics and better integration with the current generation of system controllers and the Vaillant internet gateway. If you own an older installation with a VRT 380f and are considering replacing or expanding the system, the sensoHOME 380f is a direct, more modern successor that retains the same philosophy of simple wireless installation for one heating circuit.

Additional frequently asked questions

Compatibility with hybrid and renewable sources

Modern heating systems increasingly combine a gas condensing boiler with a renewable source, such as solar hot water heating or a heat pump for part of the heating output. In simpler hybrid solutions, where one direct circuit is controlled separately, the sensoHOME 380f can continue to serve as a room controller, while switching between heat sources and their coordination is handled by the boiler's control electronics or a higher-level system controller. For more complex hybrid systems with multiple mixed circuits, we recommend consulting the specific wiring diagram with our technical team before purchase, to ensure that the sensoHOME 380f covers exactly the function your installation needs.

Summary

The Vaillant sensoHOME 380f is a balanced solution for households that want wireless comfort, weekly programming and modulating control without the need to run cables and without an unnecessary investment in a full system controller. Thanks to the option of expansion with an outdoor sensor or the VR 92f module, it is ready to grow along with the household's needs, whether that means more precise weather-compensated control or adding a second independent heating zone. Simple wireless installation, bidirectional communication with the boiler, and real energy savings make it a balanced choice between the basic wired VRT 50 thermostat and a full system controller such as multiMATIC or sensoCOMFORT.
