Explanation
Contrast
(Installation engineer
settings/ Advanced)
Adjusts the display’s contrast. The factory setting is 10.
Selectable values range from 10 to 34. The setting should not
be changed.
Curve slope
(Heating curve)
The curve slope regulates how much the flow temperature
increases in relation to the outdoor temperature. Selectable
values range from 21 to 60. Curve slope 50 corresponds
to a flow temperature of 50°C when the outdoor sensor
is registering 0°C.
Curve level
(Heating curve)
Parallel displacement of the heating curve up or down. Factory
setting 20. Selectable settings range from 5 to 30.
Alarm relay
(Installation engineer
settings/ Advanced)
To test the alarm relay, activate manual operation and select 1
to simulate an alarm signal.
Log intervals
(Installation engineer
settings/ Advanced)
This function is under development.
Log list
(Main menu)
The log list shows information about triggered alarms, warnings
and limitations.
Man. Operation active
(Installation engineer
settings/ Advanced)
To test the boiler’s functions, you need to activate the manual
operation. Select 1 to activate the manual operation and select
0 to deactivate the manual operation. Manual operation is
automatically deactivated after four minutes
of inactivity.
Manual operation
(Installation engineer
settings/ Advanced)
Manual operation is used to test the boiler’s functions
manually.
Max. flow
(Installation engineer
settings/ OTC)
The maximum permitted flow temperature. Factory setting
40°C. Adjusted according to the design of the system.
Min. flow
(Installation engineer
settings/ OTC)
The minimum permitted flow temperature. Factory setting 15°C.
Adjusted according to the design of the system.
Boiler temperature
(Current temperatures)
The current flow temperature.
Product information
(Main menu)
Displays information about the boiler’s software and hardware.
Room setpoint
(Current temperatures)
Desired room temperature. The user sets the Room setpoint via
the Room unit.
Room I-factor
(Installation engineer
settings/ OTC)
I-factor, I-part impact, 0.1°C/°C/h.
Adjustment should only be performed by a person with
an understanding of the impact!
Room P-factor
(Installation engineer
settings/ OTC)
P-factor, proportional impact, 0.1°C/°C.
Adjustment should only be performed by a person with
an understanding of the impact!
Room sensor
(Installation engineer
settings)
Activate or deactivate the room unit. (Option)
Room temperature
(Current temperatures)
Value from room unit.
Setup Wizard
(Installation engineer
settings/ Advanced)
Setup Wizard helps you to set: language, date format, time
format, activate or deactivate the OTC outdoor sensor, curve
slope, min. flow and max. flow values.
