Stylish and modern underfloor heating thermostat with colour display and individually adjustable energy-saving programmes. Perfect for those who expect the best energy efficiency and want to be able to adapt the heating to their own needs.

EB-Therm 400 is our most complete thermostat in the series. It has several different energy-saving programmes and features that make sure that it's nice and warm when you need it. 

Simplify for the installer

EB-Therm 400 is developed with the installer's well-being in focus. The thermostat is therefore easy to handle and install. The shallow installation depth means the cable fits in the box without any problems. There is also a clear and easy-to-understand start-up guide to make it easy. Everything to make it easier for the installer.

EB-Therm is compatible with most sensors on the market. This facilitates, for example, housing improvements where it may be necessary to retain the existing floor heating and just replace the thermostat.

The thermostat has a built-in countdown timer feature that shows when the underfloor heating can be started after securing with filler.

Clear and easy to navigate

With its easy-to-navigate and intuitive menus with clear icons for the different features, EB-Therm 400 makes it easy for both the installer and the end user. The 1.8 inch colour display is clear and the capacitive touch zones are outside the display area in order to make the thermostat's various functions even more transparent and user friendly.

Save energy with EB-Therm 400

Energy saving programs are adjustable and times and temperatures can both be set individually. In this way, the thermostat will be versatile and adaptable to many different environments and conditions.

RESIDENCE preset at + 22 °C.
Reduction of 5 °C Mon-Fri at 08:00-15:00, Mon-Sun at 23:00-06:00. Time and temperature can be adjusted.

OFFICE preset at + 22 °C. 
Reduction of 5 °C at all times except Mon-Fri 08:00-17:00. Time and temperature can be adjusted.

Using the timer function, you can control the heat in spaces and facilities that are used more infrequently. The heat is turned on only when needed and stays on during the set time. Afterwards, the heating will go into standby mode, for example maintenance heating and frost protection. 

The remote control programme allows you to switch temperature between two preset values. This is done by using, for example, a switch, an SMS modem or a wi-fi device. Suitable when the heating is turned on in a summer house, mountain cabin, shed or where you want to control the heating from a central location. It is also possible to set the after-heating if you want to delay the temperature reduction.  

In addition to these programmes, there are additional features that you can read about in “Smart tips” below.

Easy to keep track

EB-Therm 400 makes it easy to keep an eye on your energy consumption. The thermostat clearly displays the energy consumption per year, month or day. 

Smart tips

Thermostat with smart features
In addition to its regular energy-saving programmes, EB-Therm 400 has a variety of smart features that mean the thermostat is useful in many different applications and contexts.

The hotel programme allows you to control the heating via the remote control input with an external card reader with delay timer, since the thermostat has an integrated time relay function. Temperature settings switch automatically when the hotel guest arrives or leaves the room and the after-heating duration is fully adjustable. This makes it easy to determine how long the heating should stay on for cleaning after the guest has left the room. The guest can only adjust underfloor heating between, for example, 20-27 °C. Other functions are locked.

Homes for the elderly, special/temporary accommodation, schools, public areas
Thanks to the hotel programme, the thermostat can be adapted to other public areas where you don't want the user to be able to change the basic settings too much. With a strapped remote control input in the thermostat, the functions can be locked so that the user can only adjust the underfloor heating between, for example, 19-25 °C.

Small snow melting installations
For small snow melting installations on garden paths, residential entrances, driveways and small roofs, EB-Therm 400 can be used with the timer programme. The timer function is activated manually and the outdoor temperature must be below the set point to start the facility. An encapsulated sensor is connected to the thermostat, which measures the outdoor temperature. The heating installation is turned on/off for any sudden changes in temperature.

Year clock
With an external year clock that connects to the junction box, EB-Therm 400 can control the floor heating via its remote control programme.

Comfort underfloor heating
Comfort underfloor heating is intended to make the floors comfortable to walk on, that is to say not perceived as cold. Comfort underfloor heating even provides a drying affect and is used to complement the other primary heat sources. This feature restricts the set temperature to max 27 °C. Is most often used in low-power solutions (Thermoflex 45).
