Boiler controller KXD are modern microcontroller based devices, produced in digital SMT
technology.
KXD controllers are intended for boiler control of direct and/or mixing heating circuit or two
mixing heating circuits and d. h. w. warming with boiler, solar collectors and other energy
sources. KXD controllers also incorporate safety temperature limiter STB for emergency
boiler shutdown.

The controller requires a conrmation of language
selection with the button.
In case you chose the wrong language, return to the
language selection with the button.
INITIAL CONTROLLER SETUP
KXD heating controllers are equipped with an innovative solution “Easy start” which ena-
bles the setup of controller in just three or four easy steps.
When the controller is connected to the power supply for the rst time, the display rst
shows the program version and company logo and then the rst step of the procedure for
controller settings is started.
STEP 1 - LANGUAGE SETUP
Use buttons and to select the requested language.
Conrm the selected language by pressing .

STEP 2 - HYDRAULIC SCHEME SETUP
Select a hydraulic scheme for controller operation.
Move between schemes with buttons and .
Conrm the selected scheme by pressing .
The controller requires a conrmation of language
selection with the button.
In case you choose the wrong scheme, return to
scheme selection with the button.
Later you can change the selected hydraulic scheme with service parameter
S1.1.
STEP 3 - SETUP OF HEATING CURVE STEEPNESS FOR THE FIRST CIRCUIT
Set the heating curve steepness for the rst heating
circuit.
Change the value with buttons and .
Conrm the selected value by pressing .
The controller requires a conrmation of the set heat-
ing curve steepness with the button.
In case you choose the wrong heating curve steep-
ness, return to heating curve steepness selection
with the button.
Later you can change the heating curve steepness with parameter P2.1. The
meaning of heating curve steepness is detaily described on page 37.
All schemes with mixing heating circuit
are available for radiators and oor/
wall heating.
