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 required
to maintain the set temperature of the radiator for current external conditions (see:
Actual working time meter).
Construction of the heating element unit as well as physical characteristics of the heating
agent cause that the bottom pipes (especially the two at the very bottom of the radiator)
may have a lower temperature than the remaining parts of the radiator – this is a normal
phenomenon.
KTX 4 controller installed on the SPLIT heating element is the basic configuration of this
type of heating element unit which allows use of all the basic features of the device (see:
Local mode operation).
KTX 4 controller can also cooperate with an external wall-mounted transmitter (ie. DT-IR
type), which adds additional features to the basic set (see: Remote mode operation).
