Functionality
The ONE heating 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 characterized 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 heating element is 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 heating element has a metal housing available in chrome or powder coated finish. It is available in five shapes designed to match radiator collectors. The heating 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.

Information for Customers

Please be reminded that Terma electric heating elements must only be used in systems properly filled with a heating medium (such as water or another approved fluid, as specified in the user manual)

Important: Do not switch on the heating element unless the heating rod is fully submerged in the heating medium. Operating the unit while dry can result in damage to the product.

Always check that the heating element is completely immersed before powering it on.
