KTX 1
KTX1 is the I class heating element. The II class is also available as a SKT1 device.
Functionality
The KTX 1 has two settings: 50% and 100% of the nominal power. It is designed for use with the TS 1 heating element. The unique feature of the KTX range of heating elements is the Terma‑Split System. The Terma‑Split connector makes it possible to disconnect the TS 1 from the controller head.
Intelligent Building Systems
In the event of a power failure the heater remembers its setting (last setting used), which is useful when the device is controlled by external timers and intelligent building systems buildings.
Safety
The KTX 1 is equipped with ‘frost’ protection (ANTIFREEZE). It has a double protection against overheating of the radiator. The heating element displays warning indicators in case of malfunction.
Design
The KTX 1 has large, ergonomic buttons. A version with a cable‑masking cover, additional power on/off switch and screw connection is also available.
Colour
Available colours: white, silver, chrome and black. The heating element can also be offered in any RAL colour and Terma special colours (including brass and gold) subject to a minimum order of 100 pcs per colour.
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.
