Weather compensated heating controller
KMS-D, KMS-D+
Weather compensated controllers KMS-D and KMS-D+ are modern microcontroller based
devices, produced in digital SMT technology.
KMS-D controllers are intended for 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.

The controller requires a conrmation of language
selection with the button.
In case you chose the wrong language, return to the
language selection with the button.
INITIAL CONTROLLER SETUP
KMS-D and KMS-D+ heating controllers are equipped with an innovative solution “Easy
start” which enables 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.
Conrm the selected language by pressing .

STEP 2 - HYDRAULIC SCHEME SETUP
Select a hydraulic scheme for controller operation.
Move between schemes with buttons and .
Conrm the selected scheme by pressing .
The controller requires a conrmation 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 .
Conrm the selected value by pressing .
The controller requires a conrmation 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.

RESET
Disconnect the controller from power supply. Press and hold the but-
ton and connect power supply.
Attention! The controller will be reset and requires additional setting. When
the controller is reset, all of its previous settings are deleted.
STEP 4 - SETUP OF THE HEATING CURVE STEEPNESS FOR THE SECOND CIRCUIT1
Set the heating curve steepness for the second heat-
ing circuit.
Change the value with buttons and .
Conrm the selected value by pressing .
The controller requires a conrmation 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 P3.1. The
meaning of heating curve steepness is detaily described on page 37.

Review of data on the screen:
In the middle of the screen are displayed operation mode and active user functions. To
switch between heating circuits and the screen with the hydraulic scheme review use the
button.
Temperatures, active outputs, protection functions and other data appear in the bottom
section of the screen. To review temperatures and other data, use buttons and .
The number of sensors and other data displayed on the screen depends on the selected
hydraulic scheme and controller settings.
If you wish to retrieve the requested data after using the keyboard, look for
the data with buttons and , then conrm it by pressing the button
for 2 seconds.
If you press the button for 2 seconds, the temperature review will
change from a single line review into a double line review or vice versa. In
the two-line temperature review, the measured temperature appears in the
rst line, and the requested or the calculated temperature appears in the
