INITIAL CONTROLLER SETUP
WDC 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.
Use buttons and to select the desired language.
Confirm the selected language by pressing .
The controller requires a confirmation of language selec-
tion with the button.
In case you chose the wrong language, return to the lan-
guage selection with the button.
If you do not find the desired language in the first screen, move to the next screen
with .
STEP 1 - SET LANGUAGE

Later you can change the selected hydraulic scheme with service parameter S1.1.
Select a hydraulic scheme for controller operation.
Move between schemes with buttons and .
Confirm the selected scheme by pressing .
STEP 2 - SET HYDRAULIC SHEME
The controller requires a confirmation of language selec-
tion with the button.
In case you choose the wrong scheme, return to scheme
selection with the button.
3. STEP- SET THE HEATING CURVE STEEPNESS FOR THE FIRST CIRCUIT
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.
Later you can change the heating curve steepness with parameter P2.1.
The meaning of heating curve steepness is described in detail on page 36.
All schemes with mixing heating circuit are
available for radiators and floor/wall heating.

Later you can alter the set heating curve steepness with parameter P3.1.
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 .
1 This setting is not available in schemes with only one heating circuit.
The first and the second heating circuits are marked with their according num-
bers on hydraulic schemes.
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.
The controller requires a confirmation of the heating curve
steepness setting with the button.

DESCRIPTION AND PRESENTATION OF THE BASIC SCREEN:
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 hy-
draulic 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
