Terma Split (kl. I)
Easy to assemble
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 TS 1 screws into the radiator and is tightened with a standard 24 mm spanner, then the controller can be fitted onto the Terma‑Split connector. The connector is then hidden within the controller case.
A unique characteristic of heating elements by Terma. This innovative solution separates the heating element from the controller. the heating element itself should be "traditionally" screwed into the radiator with the spanner. The controller should then be installed on the head of the heating element. The only visible element remaining is the electric controller, as the connector is hidden within the casing.
Advantages:
- Easy and safe installation
- Capability to change the controller for a different model at any time, without any interference in the installation
- Capability to remove the controller e.g.: for the renovation period
- Capability to place the controller at any suitable angle towards the radiator (340° of rotation)
• • Capability to use a heating element of any power within the 120 - 1000 W range (independently from the controller)
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.
