EB-Therm 205

  • EB-Therm 205

Underfloor heating thermostat with display. EB-Therm 205 is the solution when you want an energy smart alternative.

Therm has two energy saving programmes. They are based on a smart and simple principle: make sure it is only warm when you need it. To make things easier for you, our thermostat can control itself. For example it can automatically lower the heating when you are at work or sleeping and then make sure it is warm again when needed. All you need to remember is to start the programme. Choose between:

Home environment Lower by 5°C Mon-Fri 08:30-15:00, Mon-Sun 23:00-05:00
Office environment Lower by 5°C at all times except Mon-Fri 06:00-18:00

Microprocessor controlled

All our thermostats are digital and microprocessor controlled. This technology means that the thermostat collects data from the time it is started up and uses this to calculate when to turn on and off. This keeps temperature fluctuations to a minimum, which gives an even heat and lower energy consumption. The temperature in the floor fluctuates less than +/- 0.3 °C.

Exact adjustment

The thermostat can regulate the temperature in three different ways: as a floor thermostat, room thermostat or a combination of the two. There is adjustable overheating protection that makes it suitable even for wooden floors, for example, which should not exceed 27°C. You can also use EB-Therm 205 to control underfloor heating for all types of floor, even sensitive materials.

The automatic ventilation function cuts of the heat for 15 minutes if the temperature falls more than three degrees in a minute.

The heat symbol shows whether the heating cable is on or off or if there is a fault in the system. The display always stays lit for 30 seconds after the last time a button was pressed. Then the lighting is lowered. You can also adjust it so that it goes off altogether. The display contrast is adjustable.
