Thermo&Multiroom – white

Wi-RT2-WM-W, 5902431679136

Temperature controller and scene controller.

Thermo&Multiroom is a modern temperature controller designed to manage heating and cooling in residential and commercial buildings. It combines the function of a traditional room thermostat with the capabilities of the FOX smart home system, enabling the automation of multiple devices from a single location.

The device can directly control electric heating with a power output of up to 3.6 kW or work in conjunction with other FOX system devices to create advanced building automation scenarios.


Key features of Thermo&Multiroom:

Temperature control

  • Heating/cooling function;

  • Direct control of electric heating up to 3.6 kW;

Support for two temperature sensors

  • Built-in room temperature sensor;

  • Option to connect an additional temperature sensor;

  • Additional monitoring and protection against dangerous overheating (e.g. underfloor heating);

Compatibility with many types of sensors

  • Supports analogue and digital sensors;

  • Easy retrofitting of existing installations:

    • the thermostat can, for example, be fitted in place of a previous light switch, providing thermostat functionality and allowing lighting to be controlled via scenes;

    • Support for multiple types of temperature sensors – the option to use sensors already present in the room.

Smart control and automation

  • Advanced automation – the thermostat can remotely control multiple Fox devices, meaning a direct thermostat–radiator connection is not required to control individual radiators in the room;

  • Integrated scene controller enabling integration with other FOX system devices (e.g. control of blinds and lighting throughout the house);

  • Local timers or timers using online calendars with support for astronomical functions, which also work without a Wi-Fi connection;

Convenient operation

  • Configuration via the mobile app;

  • Intuitive operation via a rotary knob with an LCD display;

  • Integration with home automation systems via REST API and MQTT;

Installation

  • Wall-mounted (in a 60 mm flush-mounted box);

  • Attractive housing available in three colour options.

What makes Thermo&Multiroom stand out?

  1. A modern room thermostat with a convenient dial and LCD display, allowing for quick temperature adjustments and convenient control without the need for an app.

  2. Support for two temperature sensors allows you to simultaneously control the room temperature (measured by one or both sensors) and protect the system from overheating. This is particularly useful in underfloor heating systems.

  3. Advanced schedules and scene control allow you to create complex operating scenarios using local schedules, online calendars and astronomical functions.

  4. Integration with the FOX system and other building automation systems, thanks to support for REST API and MQTT, allows the controller to be used as part of a larger smart home system.

  5. The controller operates locally, so it executes programmed schedules and maintains the set temperature even in the event of a temporary loss of internet access.

  6. Wide compatibility with temperature sensors facilitates the design of new installations and the modernisation of existing heating systems without the need to replace previously installed sensors.

The device has been designed with modern installations in mind:

  • underfloor heating,

  • heating mats,

  • heating cables,

  • electric radiators,

  • infrared heaters,

  • cooling systems,

  • HVAC systems,

  • home and building automation,

  • smart home systems.

Timers

Thermo&Energy-D allows you to create comprehensive timers tailored to the user’s daily routine. The controller can automatically adjust the temperature depending on:

  • the time of day,

  • the day of the week,

  • the heating season,

  • astronomical events.

Examples of applications:

  • automatic reduction of the temperature at night,

  • reducing heating whilst the household is away,

  • pre-heating rooms before returning home,

  • scheduling underfloor heating,

  • temperature control in offices and commercial premises according to working hours.

This solution enhances user comfort and effectively reduces energy consumption and heating costs.

Triggers and smart system responses

The FOX system allows you to create automations based on triggers – events that initiate a specific action by the controller.

A trigger may include, amongst other things:

  • a change in temperature,

  • reaching a specific temperature threshold,

  • the activation of another device,

  • exceeding a defined power value,

  • a change in the relay’s state,

  • a time schedule,

  • data from other devices in the FOX system.

In practice, Thermo&Multiroom can:

  • work in conjunction with additional Fox devices that control, for example, electric radiators,

  • close or open the blinds when the set temperature is exceeded,

  • switch off the heating when a window is opened,

  • control circulation pumps or ventilation,

  • be part of home automation scenes.

Thanks to integration with MQTT and REST API, the controller can also work with external smart home systems, such as Home Assistant and IoT platforms.


Smart home automations and scenes

Thermo&Multiroom can form part of the larger FOX building automation system. This allows you to create complex scenes and interdependencies between devices.

Examples of automations:

  • the ‘Leaving Home’ mode, which automatically lowers the temperature in all rooms,

  • ‘Return’ mode, which restores comfortable heating settings,

  • integration with roller blinds and the sun protection system,

  • automatic limitation of heating operation during periods of high energy consumption,

  • smart zone heating management,

  • integration with energy consumption monitoring.

The FOX system also allows you to create scenes that can be activated with a single click in the mobile app.

Push notifications and operational monitoring

Thermo&Multiroom allows push notifications to be sent directly to the user’s smartphone. This gives the user constant oversight of the heating system’s operation.

Notifications can alert the user to:

  • the set temperature being exceeded,

  • the risk of the floor overheating,

  • a change in the device’s status,

  • unusual energy consumption,

  • a fault with the temperature sensor.

Combined with telemetry and historical data, the user gains a comprehensive overview of the system’s operation — both in real time and historically.

How to protect underfloor heating?

For underfloor heating, it is recommended to use a second temperature sensor mounted directly in the floor. This allows you to effectively limit the maximum floor temperature and protect the finishing materials.

How to reduce heating costs?

Using time schedules and energy measurement functions allows you to reduce electricity consumption and optimize the operation of the heating system.

How to choose a temperature sensor?

  • NTC 10 kΩ — the most commonly used sensor in underfloor heating systems. A popular standard used in heating mats and cables from many manufacturers.

  • KTY81-210 — a good choice for installations requiring stable and repeatable temperature measurement, especially in automation systems and technical applications.

  • NTC 1 kΩ / 4.7 kΩ / 25 kΩ — used primarily for use with existing installations or sensors from specific manufacturers. Choosing the right version allows you to easily upgrade your system without having to replace the sensors.

Can the controller control high power?

Yes. Thermo&Energy-D enables direct control of loads up to 3.6 kW (16 A), so in many installations there is no need for an additional contactor.
