CONTROLLER SETUP AT THE FIRST START-UP
The controller features an innovative solution “Easy start" allowing the initial setup of the
controller in only four steps.
Upon the rst connection of the controller to the power supply network, the rst step of the
controller setup is displayed after the program version and logo.
STEP 1 – LANGUAGE SELECTION
Select the preferred display language. Move among
languages with the keys and .
Conrm the selected language with the key .
Conrm the correct language selection by pressing .
If the wrong language has been selected in error,
return to language re-selection by pressing .
STEP 2 – SELECTION OF HYDRAULIC SCHEMATIC
Select the hydraulic schematic for the operation of the
controller. Move among schematics with the keys
and .
Conrm the selected schematic by pressing .
Conrm the correct schematic selection by pressing
.
If the wrong schematic has been selected in error,
return to schematic re-selection by pressing .
Hydraulic schematic can later be changed with the S1.1 service parameter.

STEP 4 – SELECTION OF OPENING DIRECTION OF THE MIXING VALVE
Select the right direction of opening the mixing valve.
Move between the directions with the keys and .
Conrm the selected direction with the key .
Conrm the correct direction by pressing .
If the wrong direction has been selected in error, return
to direction re-selection by pressing .
Opening direction of the mixing valve can be changed with the S1.4 service
parameter later on.
STEP 3 – SETUP OF HEATING CURVE SLOPE
Setup the heating curve slope. Change the value with
the keys and .
Conrm the selected value by pressing .
Conrm the heating curve slope with the key .
If the wrong value has been selected in error, return to
slope re-selection by pressing .
The heating curve slope can be changed with the P2.1 user parameter later
on.

GRAPHIC LCD
All relevant data on the operation of the controller can be seen on the graphic LCD.
DESCRIPTION AND APPEARANCE OF THE DISPLAY
Notications and
errors
Operating mode and
user functions
Data display:
operating mode, user functions, notications and errors are shown in the upper half of the
display. To switch between the data display and display of the hydraulic schematic use the
key .
To review temperatures and other data use the keys and . The number of sensors
and other data that is displayed depends on the selected hydraulic schematic and control-
ler setup.
To recall certain data after the use of keyboard, search for it with the keys
and and conrm it by pressing and holding for 2 seconds.
By pressing and holding the key for 2 seconds, the temperature display
changes from one-line to two-line display or vice versa (only if the condition
P1.9=0 is met). In the two-line temperature display (P1.9=1), the rst line
shows the measured temperature value and the second one the preferred or
calculated temperature.
