INITIAL CONTROLLER SETUP
W.. heating controllers are equipped with an innovative solution which enables the
setup of controller in just three or four easy steps.
When the controller is connected to the network for the first time, the display first
shows the program version and company logo and then the first step of the procedure
for controller settings is presented.
STEP 1 - SET LANGUAGE
The controller requires a confirmation of language
selection with the button. In case you chose the
wrong language, return to the language selection
with the button.
Use buttons and to select the desired language.
Confirm the selected language by pressing .
If you do not find the desired language in the first screen, move to the next
screen with .
All schemes with mixing heating circuit are
available for radiators and floor/wall heating.
STEP 2 - SET HYDRAULIC SHEME
Select a hydraulic scheme for controller operation.
Move between schemes with buttons and
.
Confirm the selected scheme by pressing .

EN INITIAL CONTROLLER SETUP
Later you can change the selected hydraulic scheme with service
parameter S1.1.
Later you can change the heating curve steepness with parameter P2.1.
The meaning of heating curve slope is described in chapter “heating curve”.
3. STEP - SET THE HEATING CURVE STEEPNESS FOR THE
FIRST CIRCUIT
The controller requires a confirmation of hydraulic
scheme with the button.
In case you choose the wrong scheme, return to
scheme selection with the button.
Set the heating curve steepness for room heating for
the first heating circuit.
Change the value with buttons and .
Confirm the selected value by pressing .
The controller requires a confirmation of the set
heating curve steepness with the button.
In case you choose the wrong heating curve
steepness, return to heating curve steepness
selection with the button.

9User Manual
ENINITIAL CONTROLLER SETUP
Later you can alter the set heating curve steepness with parameter P3.1.
The first and the second heating circuits are marked with their according
numbers on hydraulic schemes.
4. STEP - SET THE HEATING CURVE STEEPNESS FOR THE
SECOND CIRCUIT1
Set the heating curve steepness for room heating for
the second heating circuit.
Change the value with buttons and .
Confirm the selected value by pressing .
The controller requires a confirmation of the
heating curve steepness setting with the
button. In case you choose the wrong curve
steepness, return to heating curve steepness
selection with the button.
RESET
Disconnect the controller from power supply.
Press and hold the button 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.
1This setting is not available in schemes with only one heating circuit.

REVIEW OF DATA ON THE SCREEN:
Operation mode and user functions appear separately for each circuit on the upper
third of the screen. 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
middle 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 desired data after using the keyboard, look for the
data with buttons and , then confirm 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 first line, and
the desired or the calculated temperature appears in the second line.
