Heating element KTX 4

Stay close to nature
What makes this device exceptional is not only its attractive design, nor its extended function options, (desirable as they are), but the fact that it has a function which allows the user to control energy consumption. Our customers have benefitted, most notably, from this device's energy consumption control function, so, if energy consumption is a concern for you, this device is a most desirable solution. The KTX 4 device uses an IR infrared sensor to cooperate with an external IR control panel dryer function, with the option to program your heating time of (1-4) hours via a "working time" meter. The device allows you to be in charge of energy consumption and offers 5- step radiator temperature regulation.

KTX4 is a class I heating element. The class II is also available, see SKT4 device.

The KTX 4 has 5 temperature settings that range from 30°C to 60°C. An electronic sensor guarantees precise temperature control. The device displays the currently set temperature level and indicates the status of the heating cycle or standby state. The KTX 4 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. The KTX 4 is also equipped with actual heating time counter for energy consumption calculations.

An enhanced timer automatically turns the heating element off after 1, 2, 3 or 4 hours.

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

Intelligent Building Systems
In case of power loss the KTX4 remembers its settings making it suitable for connection with external timers and intelligent building systems.

The KTX 4 is equipped with a ‘frost’ protection (ANTIFREEZE). It also has double protection against the element overheating as well as a safety feature that prevents damage in case of operation in a dry radiator. A device error or malfunction is identified by a display of error codes.

Equipped with an easy to read single digit LED display in blue. The device has a screw connection and a version with a power cable masking and additional on/off switch under the cable housing is  available.

Available colours: white, silver, gold, chrome and black. The heating element can also be offered in any RAL colour and Terma special colours (including brass) subject to a minimum order of 100 pcs per colour.
