KTX 4 Blue
The KTX 4 Blue electric heating element is equipped with a ba-
sic sensor for controlling the temperature of a radiator/towel rail
and, depending on the version of the device, an additional sen-
sor for controlling room temperature. Note: the factory settings of
the heating element read the temperature of the radiator/towel
rail. The built-in room temperature sensor* can be activated with
the mobile application.
* Does not apply to MS version
All versions of the Blue heating element (also the MS version) can
be connected to an additional external room temperature sensor..
Buttons and are used to regulate temperature whilst the

mum power for the whole time it is on. On turning the device on, it
operates with the nominal power for a short period of time in order
to heat up the radiator to the set temperature. After that it turns
itself on and off periodically, using only as much energy as it is re-
quired to maintain the set temperature of the radiator for current
external conditions (see: Actual working time meter).
The basic temperature sensor allows you to precisely control the op-
eration of the device and protects the user from getting burnt by
limiting the maximum operating temperature to 60°C. Additionally,
a thermal fuse, built into the heating rod, protects your radiator from
critical overheating (the fuse can get damaged in temperatures high-

er than 82°C — this is especially important for heating elements in-
stalled in dual fuel radiators, connected to central heating system).
