Our main goal was to create a practical and easy to use heating element which does not dominate the radiator with its form. ONE has all the basic functions necessary for everyday use – two heating levels as well as an automatic switch-off mode (after 2 hours). All the functions are controlled by just one button and the current working mode is shown by means of a single multi-colour LED. The heating element is capable of wireless IR communication with an external wall controller. The casing of the ONE heating element is finely attuned to the radiator collector shape, making the heating element almost invisible.

Functionality:

The ONE electrical element allows you to set two temperature levels. A sensitive electronic sensor allows the device to maintain the set temperature. The device shows the current mode using a multi-coloured LED. The heating element is characterised with a very low power consumption in standby mode.

TIMER

The timer automatically turns the heating element off after 2 hours.

REMOTE CONTROL

The heating element is capable of wireless IR communication with an external wall controller, which enhances the use of the ONE heating element with additional features.

INTELLIGENT BUILDING SYSTEMS

In the event of a power failure, the heating element remembers the previous setting (last setting used), which is useful when the device is controlled by external timers and intelligent building systems.

SAFETY

The ONE electrical elements are equipped with a number of safety features including; a ‘frost’ protection setting (ANTIFREEZE), a double protection against overheating and an ‘active’ protection to prevent overheating when used in a dry radiator. Device displays a warning in case of malfunction.

DESIGN

The electrical element has a metal housing available in chrome or powder coated finish. It is available in four shapes designed to match radiator collectors. The electrical element has a single hidden button to activate and change the settings. There are radiators available with the ONE integrated into the radiator where the only part of the ONE that is visible is the status indicator.
